Nexus 7 Head-unit Install
Hi all, long time reader, first time poster. I'm working on a Nexus 7 Car Head-unit install, and figured I would post my working through the install, hardware, software, and kinda just help all the tons of people I see out there who have the same idea, but just have no idea how to go about it.
This is ment to be half a tutorial (once everything is done) and half a brainstorming to give me idea's for things I haven't thought of or considered. I'll be coming back and updating this OP with pictures, and the build as it gets worked on.
Goals of the Install
I want to be able to run my entire car off the Nexus. I have already set up wifi tethering from my S3 to get internet into the Nexus, and thus open up a realm of possibilities. Necessary features are Nav, and Music. I rarely call from my car, but in car calling would be a nice feature to have as well. I also go out to the track ever now and again, and adding car stats (boost, RPM logging, acceleration, mapping) would be great. The biggest reason to do the install is that one the hardware is configured, you literally have a ultimately customizable setup that will take years to outdate.
The Hardware
1 x 2003 Subaru WRX
1 x Nexus 7
1 x Samsung Galaxy S3 (T-Mobile)
1 x MRX-V60 - Alpine 5-Channel Subwoofer Amplifier
1 x 7 Channel Equalizer
lots of hacked wiring
The Software
This is where I would love some feedback on on what I may be missing, better solutions to what I have suggested, and just some general awesome idea's!
Music:
Pandora, Play Music, DI.fm, Soundcloud, Radio.com
In Car Phone/Text:
Talkatak, Google Voice
OBDII Support: (Future Project)
Right now this is not a nessiacty as the hardware to do this could get very tricky. However I know I can read from the OBDII port with a bluetooth OBDII dongel and an app like Torque Lite. However I do own a tatrix cable, and am considering if it would be possible to go from the USB to the tablet, and find an app/write one what allows for the tablet to control the car in real time.
Nav:
Google Navigation, Local
Track Apps:
aLapHD
The Two Builds
There are two ways to go about this. The first would be the simple and easy way which is to hack together a charger wired to the power source of the car, and use that to keep the tablet charged. Then run a 3.5mm audio into the amp, and have sound run from there. There are a few issues with that. 1. There will be no volume control, as the Tablet's buttons will be part of the center console. I suppose I can run a controller to the amp, that will let me adjust volume. 2. This will not allow for the possibility of adding OBDII support.
The second option is to purchase a micro USB dock that does audio out. Hack it apart, and run the audio to the amp, and the power to the power. This would be necessary if I want to do a full USB ODBII connection (I believe, please tell me if I'm wrong), and would be much "cleaner" when it comes time to take the tablet out of the car for any reason (hardwire sync, parking in the "ghetto").
What I need Help with
Have any idea's. Tried something similar and have some tips. Have suggestions for apps, hardware configurations I haven't listed, or just generally want to say "sick man". Please let me know. I would love to have some people who are also interested in doing this join in on my build, and we can work together to eliminate any issues to make tablet installs easier. I will be coming back and updating this OP throughout the entire process so please look for updates!
Thanks All!

Check out a half-DIN equalizer or crossover to solve your volume, fading, equalizing concerns... can't post a link because this is first post!
I'd like do do this in the future... I hope someone comes out with a custom set of apps that make this really cool and easy... maybe even a custom ROM.
Basically what I'd want out of this is:
Auto-on with power. Auto off after 10 minutes of no power. FM radio tuner. Maybe the ability to connect a rear-view camera (wifi?). Bluetooth OBDII would be good enough for me.
I'd also appreciate the ability to connect to at least one camera and use it as a DVR, but I think that it would probably be beyond feasibility with the Nexus 7...
What I really want to see is the ability for the Nexus to be a full Bluetooth head unit. I want it to pair with my phone for both internet (already do this, works great) and have it act as a headset essentially. This is the part that appears to not exist anywhere. The ability for the Android Tablet to act as a hands free device. I mean if a car stereo can fully integrate with your phone read your address book, start and answer calls hands free, stream music, everything from your phone then why the heck not the tablet! Someone needs to write the BT stack that can handle that. Apparently it doesn't exist for android. It exists for Windows, but not Android. That is just wrong. Are there any car stereo head units running Android as their OS? If so can someone dump their rom so we can see what all it can do for a project like this?
I really want this!
I have had mine in the dash for a couple weeks now, streaming Bluetooth to the radio which I relocated, also using NFC sticker to turn on WiFi, bluetooth , set audio volume, screen brightness and start playing music. Tasker to put unit into car mode, its sick! I'll be following, really interested to see what you come up with. My car is N 06 altima and the Nexus 7 fits almost like a glove where factory stereo use to be.

Hi!
Can you upload a picture of your install? I own a altima and I am looking to install the Nexus 7 on my dash as well. And also, did your factory stereo have bluetooth? If not, what are you streaming bluetooth to?
Thanks
Just gonna subscribe as I thought of doing something similar

If anyone can post on his site, tell him to connect two middle pins in usb plug, then it will start charging from the lighter socket.

Does anyone know of a micro USB dock/cable that then splits to power, usb, and audio? I know of one's that will do 2 of the three, but nothing that does all three. Maybe just a USB and power one, and run the audio straight out of the 3.5mm on the N7.
Amp was ordered, and will be here next week. Prelimanary fitment pics coming soon...
Hello, I'm considering permanently mounting a nexus 7 in my car. It seems like the perfect in car device.
With this in mind I have updated my CarHome Ultra app to better accommodate the Nexus 7 screen. I will be posting a new video soon showing it running on the 7.
I've looked at doing this as well, I've always been prevented by the issue of the FM radio. I use the car a lot in places where I get no or poor connection via the phone, but the radio works fine, so loosing it would not be an option as I use the FM radio quite alot.
I've been trying to figure out away to control an FM radio via the Nexus so if anyone out there has any info it would be greatly appreciated.

I am actually currently doing a very similar project with a Nexus 7 and my Nissan 350z
I am planning on installing the Nexus 7 inside my dash (to replace sat nav dash)
HOWEVER
what about routing the power button on the tablet? Because If you cant access the power button the tablet will only get power when the car is on and if you dont use the car for a day or two the tablets battery would go flat and next time you turn on the car the tablet would go into charging mode (screen with charging battery only) and not boot up into android jelly bean.
Theres 2 potential solutions:
1. Open the tablet and wire the power button to a custom one, however on opening it I have found the button is actually a physical push press button and cannot be wired.
2. There is potential to change a file on the android system to tell the tablet to boot up when a charger is plugged in, check these threads:

Never had any problems with it.
Despite working in the car industry and loving gadgets and mod-ing...I haven't really seen what people are up to these days in terms of car mods. The Nexus 7 makes so much sense and looks great!
Hey all
Just to add to the discusion;
Radio/DAB
Frontier silicon are the only company that I can find that do an app that can control an external radio and stream it's signal to the tablet as opposed to picking up the signal over the cellular network.
App:
Their page
http://www.frontier-silicon.com/products/software/DOK_App.html
Play store
http://tinyurl.com/d24gwm4
Module:
http://www.frontier-silicon.com/products/modules/briefs/Venice6_PB.pdf
now the problem with this is, aside from building the module in somewhere' the audio out as it feeds out of the module, but I was thinking I could use some form of y split cables near to my amps 'in'.
Media storage and playback
As far as storage for everything video/audio atc and a player to match I was thinking of useing xmbc
http://xbmc.org/
andriod port;
http://forum.xda-developers.com/showthread.php?t=1813089
and pairing this with a WiFi DLNA HDD that I would wire in remoted off (say in the boot)
GPS
For improved gps I was going to use an external bluetooth gps reciver then allow mock locations on the tablet, there are also a few apps that help with this.
This app seems to have good support and a nice help page.
App:http://tinyurl.com/a9s7gvo
An example of a external GPS receiver
http://tinyurl.com/a339vu7
Hands Free
The only work round I seem to have found atm though far from perfect is this
http://www.scosche.com/consumer-tech/product/1919
it allows you to to 'cut in' the audio stream, but (can't fins the tread now will keep looking) the guy who was playing round with this was having audio issues.
not an idea solution but workable.
before my mind starts melting again;
How I plan to implement the tablet is to use tasker to wake the tablet when power is supplied then shut of down after, if I disable all kinds of connectivity when tablet shuts down then reactivates when it wakes up everything should run smoothly. Power will be cut because I'll wire in the ignition live, like you do in a stereo anyway, an this shouldn't put a drain on my battery to much, an if the dash build is good it shouldn't be too much of an issue extracting the tablet to hard boot anyway.
Volume and Audio
Volume and audio quality is another issue that needs to be addressed.
http://tinyurl.com/d2zbbnf
Seems like an ok work round.
Another way would be to install a direct in-line volume control as suggested in other threads, and put in an external DAC or hardwired EQ.
On a side note I came across this........ http://www.crutchfield.com/p_773AIRDAC/NuForce-Air-DAC-Receiver.html?tp=59282 ........ although you need to use their plug in senders but I'm sure this can be worked round with the knowledge on this forum, an would provide a very nice solution. then again there are quite a few bluetooth devices around. this probably wouldn't allow for in-line controls though.
well thats it for now, hope this helps push this forward to a working system
ben

I thought it may be interesting to have a thread where Nexus 6 users with the supporting hardware systems could post: Tips, How to's, experience, etc. about the Android Auto APK and Nexus 6 devices. Please feel free to enlighten all who enter. :good:
Android auto is just a remote display and sound, isn't it? I don't find it particularly interesting since it *depends* on the phone for the "android" aspect. It is a much better option to install an Android HU in the car, then it isn't functionally dependent on the phone.
Not sure if you're asking or telling.

It is a mobile application for using your phone in a car. It displays on the cars touch screen and is controlled by voice commands. It only uses the bluetooth stack for phone calls, all other sound and video comes from the phones usb port. This equates to better audio and clear, crisp video. By the way, it only works on the latest Android HU.
i've been using it with my Pioneer 4100-NEX, it works quite well. i wish you could swipe away cards and have more notifications push though (ie, sms and hangouts come through, but not facebook messenger)
all in all i'm pretty happy with it, it's fast, simple, pretty and i've been pleasantly surprised with how responsive the resistive screen on the HU is.

HU does *not* require android to work with android auto.
If you want to try out Android Auto you can sign up for the beta of the app called AutoMate. First you'll need to join the beta group in Google+. Next you'll have to agree to be a beta tester with google play. Then you'll finally be able to download the app. I have been using the app for a couple of days now and I personally think that it is great. Its just like Android Auto, at least from what i've seen in all of the android auto demos. I have a pretty good car mount that can fit the nexus 6 so when I took a 4 hour trip this weekend everything worked flawlessly. The best part is that you've already got a giant 6 inch capacitive screen, why not use it instead of paying at least $800 for the cheap resistive screen version of the pioneer head units.
I have a pretty interesting issue where my Android Wear watch (Moto 360) is being CONSTANTLY pinged by my Nexus 6 while plugged into Android Auto. For the life of me, I can't figure out why. Maps is the only app I use regularly in Android Auto and I have it muted on Android Wear...yet, it's draining my Moto 360 battery QUICKLY every time I plug in. It's the strangest thing. I've had to start putting my 360 into Airplane mode to avoid problems while driving. As soon as I unplug the Nexus from my Android Auto HU, I then have to reconnect my 360 in the Android Wear app...or else it won't reconnect and continues to drain battery.
Seriously the weirdest thing.
yeah I have the pioneer 4100nex and originally was using a Moto G and it works great and then I preorderd the ATT galaxy S6 Edge and received it on tuesday, well the S6 edge doesn't work with the Android Auto, so I returned it and just bought google play edition Nexus 6 64gb, and works perfect, I really like the google navigation, reads texts and you can voice reply to the texts,you can play your google music, I`m very happy with it.:good:
That is not the purpose of this thread.

I like to believe we all know how to use our phones hands free in a car and need no special app to do that. That's the way most of us have been doing it for the past six years or so since the smartphones came out. A simple bluetooth radio used to give you all you needed paired with your phones screen. But now it's much easier to get into your car, plug your device into your hidden USB port and let it charge with screen off and have a heads up display on your radios big screen while the audio is streamed through USB and the only thing using the bluetooth stack is the phone part of the phone. Sound quality is vastly improved and everything runs so much smoother. Plus the steering wheel controls for answering calls, activating OK google and other voice related options allows you to keep your eyes on the road and your hands upon the wheel.

First if your car already has Bluetooth like mine then you still have all of the same controls as the actual android auto head units. Also just like on my phone it's not like you can just say OK Google with the music playing but if the music isn't at least I can just say OK Google even with the screen off as well and will get a response. More that likely a person will still end up looking at the device or take their hands off of the wheel when giving a command. I mean come on, Google now works but everyone knows that it's still not perfect yet. Even on my phone I still have to type out what I'm saying even if I'm annunciating perfectly just FYI... Bluetooth audio has also vastly improved over the years. I would argue that the average person would not even notice the difference between Bluetooth audio and being playing directly over USB. Also don't say that it runs 'so much smoother' because most of us have seen the videos and they are still laggy and still not as responsive as our phone themselves. I was simply giving an option to people who wanted to try out android auto without having to buy a crappy resistive screen head unit unless you wanted to shell out over $1000 for one. Also is not a heads up display... A heads up display would be something out in the area of where the driver will be looking out of the windshield as to not having to take their eyes off of the road ahead.
Please.

Please try and understand what I started this thread for. It is for those of us who are using Android Auto with a supporting head unit. Just like back a few months ago, I was using the sync system in my car. I have never had any issues with my voice to text, every once in a while a word would be incorrect, but the more you use it in a quite environment the better your results get. My text messaging reads back my response before it sends and I can either allow it to send or say the message again. I have not had to touch my phone in a car for five years and don't plan on doing anything like that today even with the radios display. The idea of hands free is exactly that, Hands Free. If you don't have the tech to support and help contribute to developing apps that help alleviate the use of hands in the car, this is not the forum thread for you. I don't know what music application you prefer, but the ones I use I pay a premium for because they offer me higher bandwidth and truer sound. And you can immediately here the difference between bluetooth and wired. It's been rumored already that Bluetooth is soon to become extinct and it seems that is the way mobile tech is rolling. BTW, HU the way I was using it my Head Unit not heads up.
The good part is.....

That would be the ideal, but very few cars come with a built in cellular connection, I know they are available but this is the inexpensive way to go. What I like the most about it is the ability to put the phone in my center compartment where the USB outlet is hidden, shut the compartment while the phone is charging and still have access to all of my phones functionality straight from the steering wheel. It's wonderful not to have to look at a screen, and if I do glance at the screen to see a turn that might be coming up or what song is playing on a stream, it is big and clear and takes not even a second to see. Luckily, the Navigation in google maps is pretty trustworthy and gives voice commands with plenty of time to spare so it's rare to even have to look at the Map when moving. My next car will have built in cellular service, it was just still to expensive four years ago when I bought my car and my service provider did not have a system in place for plugging in their tech. They do now but I won't be in the market for another car for at least another year. The thing that got me into having a Android Auto supporting HU is my text messaging application and the sync system, would not play nice together anymore because of changes in Lollipop from kit kat. Sync kept crashing the bluetooth sharing feature anytime I received a text. And since I was using that tech for the past four years, there was no way I was going back to having to touch a screen or try and type a text in the car. The developers I work with tried many fixes to see if we could alleviate the problem, but every thing we tried failed. The problem was immediately remedied with the new HU. Now I'm trying to find others that use the same tech, so we can share our experiences and any other useful features we find or help each other with certain problems one might experience. That is what this thread is about. If you have a Android Auto compatible HU and a Nexus device, this is a place to share.
feedback non-existent in H/U forum so thought i'd try my luck here.
seeking recommendation to be installed into RSX
back in January I looked into Android Auto/CarPlay from the brand names but they require USB connection to phone = dealbreaker
not looking to DIY a tablet into the dash
LF a 2DIN head unit that works very similiarly to AA without the wires.
I'm looking to have run this app pretty much on default
http://www.androidcentral.com/hands-automate-android-auto-your-phone
will be installing myself
to be used with Galaxy Nexus GSM on 4.3...quite long in the tooth my next phone is likely Note 5 or the new LG Nexus
convenience is key. I just want to enter the car and have BT auto connected to the phone and ready to stream music without having to pull out my phone.
voice-enabled messaging, google apps, backup cam, capacitative touch screen are all requirements. volume knob, 2gb ram, quad-core processor and large community dev support would be nice.I didn't look at Hufei and AN-21 because their specs are dated as they've been around for a while now. I've been waiting for android 5.0 head units to hit the market but it's taking forever.
i'm not an audiophile so as long as the sound quality isn't worse than a stock Honda radio I'm good which is only mediocre at best.
I think you're confused about a few things.
1. Android Auto requires USB, period. It doesn't work any other way.
2. AutoMate is not the same as Android Auto. It's a launcher that looks sort of like Android Auto. It has nothing to do with your other phone, bluetooth, etc. It's standalone. If you want to stream music from your phone you're gonna have a bad time.
The NU3001 is the best (i.e., most modern) head unit available today. Because the source code is available the community has developed a ROM that is car friendly and does work with bluetooth streaming, Google Now, etc. You can run AutoMate on it if you want but I finally uninstalled it as it's just a (pretty) layer that gets in the way between your maps/music/phone apps and you. There are variants available with a physical volume knob but to my knowledge they don't have one for a Honda.

Android Auto has Wifi support built in, but AFAIK my Headunit app is the only way to make it work at present, unless you have access to some unreleased devices/apps.
To Original poster: I don't think a solution with all the features you want exists yet. We've been waiting for decades for useful, robust implementations of the sort of environment that Android Auto and CarPlay provide.
I hope that within the next 2 years we will have solutions that are useful and "just work". The ones we have now clearly need work and seem as immature as Android 1.x and 2.x compared with the Android 5.x/6.x level solutions we want.
I know I'm missing something about AA, but let me ask this newbie question anyway. Oh silly me ..... what is/are the advantages of AA ..... what if users like me are happy with our car sound and video system but just want a Google centric pc and display in the car. You can buy Android mini pc like Minix, Tronsmart and others for around $200 USD or less. 16:9 HD displays with usb touchscreens have dropped in price, so mount one instead of the Garmin type Navi screens.
Yes, for connectivity you do need a wireless technology bridge from LTE to cat5 wired. But really (!), for $500 or less you get great Android system built into your car and you get to operate your sound system seperately. You can mirror or even 'sidesync' between car pc and phablet/phone if you want. Heck, with those smart TV type boxes you can watch all kinds of stuff. With a little thinking, you can connect audio into your existing sound system. You can use any number of ODBII devices to connect to your car's port and run the Torque app on your car Android pc to have all kinds of car diagnostics and live meters. You have almost the entire Google ecosystem available like any other device (almost).
What does Android Auto get you?
I apologize for asking such a seemingly silly question. Why does everything have to become so complicated and expensive?
The promise of Android Auto and its current reality don't quite match up yet but it is very early and I think it is a matter of time.
AA (and CarPlay) is meant to surface the most important functions of your smartphone and provide a more integrated and less distracting way of interacting with those functions. More integrated in terms of working with steering wheel functions (e.g. volume, next/prev, voice command, etc) and current media playback (e.g. pausing or muting existing audio to deliver turn-by-turn instructions). Less distracting in terms of simplified UI with less touching/typing required and more dependence on voice commands. It also eliminates non-essential notifications while driving (I don't need to see the latest Instagram post until I am parked thanks).
I think it also showcases to auto OEMs what is possible with some good design thinking. I own a 2014 VW with the most unintuitive, cumbersome, slow, frustrating navigation you could imagine. An Android Auto head unit that provides an excellent Google Maps nav experience is light years ahead of a system like that.
Dropping in a smartphone Android interface into a dashboard misses much of what AA is meant to deliver. It may be somewhat more integrated but it is no less distracting.

You can buy Android mini pc like Minix, Tronsmart and others for around $200 USD or less. 16:9 HD displays with usb touchscreens have dropped in price, so mount one instead of the Garmin type Navi screens.
Yes, for connectivity you do need a wireless technology bridge from LTE to cat5 wired. But really (!), for $500 or less you get great Android system built into your car and you get to operate your sound system seperately. You can mirror or even 'sidesync' between car pc and phablet/phone if you want. Heck, with those smart TV type boxes you can watch all kinds of stuff. With a little thinking, you can connect audio into your existing sound system. You can use any number of ODBII devices to connect to your car's port and run the Torque app on your car Android pc to have all kinds of car diagnostics and live meters. You have almost the entire Google ecosystem available like any other device (almost).
What does Android Auto get you?
I apologize for asking such a seemingly silly question. Why does everything have to become so complicated and expensive?

Your "build your own Android mini-PC" idea will seem VERY complicated to "regular people".
Regular people can buy a new car with AA HU installed, and simply plug their stock Android phone in. Or buy an aftermarket HU and have any of thousands of shops install it for you. How may shops will build, configure and install a custom mini-PC ? Mp3car.com MAY do it for $10,000.00 or more I guess... (See their website for custom work.)
Android Auto, after a few years of fixes and new apps supporting it, will hopefully provide a "just works" solution.
Android/computing enthusiasts may prefer to build their own systems and spend many hours tinkering etc. Or they may just want a "just works" solution here too.
Different audiences, different requirements.
Good points .... marketing savvy ... I like.
Just bought a used 2007 Toyota Solara SLE convertible (with JBL 7 speaker system), and looking to replace stereo. I've read up on here and elsewhere about some of this, but still have some Q's before moving forward.
Main needs:
Spotify (strongly prefer NOT to use bluetooth due to audio compression)
GPS (The larger the screen, the better for this)
Theft-resistant (Either looks not worth stealing, has removable face without wearing out connectors, is built-in and looks hard to steal, etc)
I'll drill down on the details in a bit, but I'd like a little perspective first on reasons why it would matter if I go with a dedicated head unit, or possibly get the fiddly bits and hook them up myself to do something like a slide-mounted Samsung tablet that I can easily pop in and out.
1) Is there some reason in general why one path is better than the other?
2) If I go DIY route, I've been reading up that Android Auto is not available for tablets without data (wifi only versions). Can't tell if that info is outdated, or still true. I see a few mentions of 3rd party workarounds, but not much info on how they are working.
3) I'd really prefer a larger readout as I use GPS heavily on a regular basis. The detachable ones I see for 10.1 screens from Joying, etc look to have connectors NOT designed for daily plug/unplug. Do these hold up?
4) Is it better for theftproofing to have a removable face, or something smaller that fits in the double din and looks harder to steal?
5) If I do the DIY route, does the audio come out of the tablet via usb and need a d/a, or out of the phones jack?
5) There seems to be info out there for DIY to get the steering controls working, car info like tire pressure, temp, etc. If I then already have the amp, and can work out the audio, and get info to and from via bluetooth with my phone or using my phone as hotspot, that's all bases covered, right? Is there anything I'm missing that CAN'T be done this way and would be better off just getting head unit?
6) Are the dedicated head units less updatable or anything like that than something like a samsung tablet?
7) Is there an issue with my 7 speaker system? Haven't checked, but I'm under the impression from some conversations I've had that there's a 7 speaker dedicated amp currently in place (not part of existing head unit). I read something about certain versions of AA not supporting subs. Not sure what that means. If I'm replacing head unit with full DIY rig, can't I just sent audio to the amp, and it splits from there, or does processing and separate out for sub need to somehow happen prior to the amp?
FYI: Asking in part because I'm thinking about getting a tablet anyway, and might as well have dual use if possible. Also, I'm considering idea also of leaving the stock stereo as is (has BT for voice, but not audio streaming), and rigging a detachable dock for tablet that then feeds audio via the aux input. I guess if I go this third route, I'd store music on it locally, and use it's wifi with my android phone as mobile hotspot to get new tracks, access map data, etc.
Thoughts on why one path is better?
Too many q's?
Available info in another thread? (I've searched and read all I could find)
Better in another subforum? (Connected car maybe?)
Thank you for the questions it is helping me do more research.
If any one can answer part of a question please chime in.
1. Android tablets (Samsung, LG) over Chinese (KLYDE, Joying, etc) units:
- better screen - even an old Galaxy Tab3 has a screen 10x better than any chinese in-car unit.
- cleaner Android implementations - chinese units suffer from poor system implementation that generates lots o0f issues with Bluetooth audio quality, OBDII pairing, WiFi and 3G/4G compatibility
- software upgradable - again, my Samsung Galaxy Tab3 from 2013 runs Nougat. My Klyde in-car unit runs Lollipop
- better RAM, usually
- more flexible in implementation
Chinese (KLYDE, Joying, etc) units over Android tablets (Samsung, LG):
-easier to install
-FM radio
-some level of integration with the car's systems
2. Since version 2.1 Android Auto is a standalone app so it will run on WiFi only units
3. No idea. But if I were to take the DIY road, instead of removing the tablet I'd have a fake panel to cover the screen, with the front part of a cheap stereo.
4. It depends on your preferences. Audio will be much better if run through an external d/a converter but you can start with getting the signal from the headphone jack and add a converter later.
Probably 2 main differences:
Android tablet wont have good amplifier. Not so good sound, you must install many apps from yourself (this is good and bad), no radio probably or bad radio. You must also connect an antenna for the radio if the tablet has one.
You must also do some modding by yourself, connection for power etc. Probably use tasker for some things, search in youtube and other places for suitable script. Xposed, app settings will help for making many apps more car like.
Search for car launcher etc.
I am writing this as i have installed in past, not tablet but mobile phone (an old galaxy s2) in a Fiat punto. So i have done those im Writting for.
If you give time and efford at the end it could be better the result compaired with a dedicated one.
The dedicated one has the benefit of don't search at all. Just install, plug and play. Probably better sound.
If it has android, you can make many things with this. Probably most as the tablet i wrote before.
If it only has android auto you can do only basic things..

Ok, I had both approaches with 2 different chinese units and one Zenpad.
- 1st Chinese unit, piece of .... so I almost smashed it with a hammer in a fury rage, so got it sold after 3 month, conclusion stay away from XTRONS!
-2nd I had a Zenpad built into my dash, lucky enough for me my dash was big enough to easily fit in an 8" tablet. I bought a mechless Sony car radio, which is much smaller than a normal unit and I hid it behind the tablet, steering wheel remote control still worked, so I could control the radio from the steering wheel, but never needed anything else than adjusting the volume. I did not use FM radio at all. See attached picture. This has a few potential problems, most probably you won't be able to charge the device & use the usb port at the same time, you will need a custom kernel for that or a USB-C tablet. Also its much more difficult to fit it in properly, when the system freeze or crash and you need to hard reset it, it can be painful, however overall I was very pleased with my setup. Since you cannot use the tablet for the bluetooth hands free I still needed to use a Himbox HB001. TIP: The install was done with the help of a 6mm acrylic sheet, which I cut to size using a jigsaw.
-3rd changed the car and couldn't do the same thing in the new car so I bit the bullet and bought another chinese unit, this time I went to an Intel based one. So far so good, I have only done about 1000 miles with it but it looks to work OK, boot up is really quick, bluetooth A2DP quality is good (not like the crap XTRONS), handsfree quality seems decent, but I need more feedback from others on this, I hear them clearly the question is how good they can hear me, so I can recommend the unit: http://www.ebay.co.uk/itm/301955449854
And now to the Android Auto question, they run on all of them, just use my app: https://forum.xda-developers.com/ge...ndroid-4-1-headunit-reloaded-android-t3432348
