Tyre Pressure Monitoring System (TPMS) For MTCB Head Units

TPMS has beenn mentioned a few times in the original thread, but AFAIK no one has managed to find out how/if any TPMS modules will work. I bought a TPMS module from Klyde, it comes with 4 valve caps and a strange mini USB thing that I assume allows you to plug another mini USB device into the unit at the same time.
Unfortunately I cant get it to work with the built in TPMS app that started appearing in ROMs from June either on my old unit or my new one, I ve tried searching for the device in the BT app and the BT in settings but I get nothing, I m awaiting a response from Klyde.
If anyone has any ideas on how to get it to work then let me know, but its good to see TPMS hardware available for these devices - even if its not working . . yet !

Can you share link from TPMS module?

My brain is stuck what is TPMS? I am sure I should know but i don't get it
Guess youre talking about Tire Pressure Metering Sensor?
would you probably add a hint to your OP and title so others know what you mean? Remeber the non-english-speakers here

Yes this is it (Tire Pressure Metering Sensor).

I simply bought it from Klyde, there was no link, I guess you have to ask them.
It turns out it cant be used with DAB, which is why I cant get it to work - the cable to attach it is the same as the DAB module they sent me.
I m not sure if its BT or maybe NFC or something. I ll report back with results when I get it to to work

Does anybody try this TPMS solution with his HU?

Does the app work in landscape mode?
Can the app start with background mode?
Does the external (valve cap) sensor show accurate value?

I have been using this TPMS system in Volkswagen Polo and my MTCB head unit since 3 months now and couldn't be happier with it.
It activates when you press the button because it invokes the reverse camera display source every time you call it into action.

I have tried these two models purchased at Amazon and they work perfectly. I have them installed on my cars.
The only drawback is that you need Bluetooth 4.0 and HuiFei radio does not have it. I have commissioned an RX USB Bluetooth for Android on Deal Extreme, to see if it works.
So far I'm seeing it in my S5 Galaxy.

Turns out you need a special lead that I wasnt sent orignally, it plugs into one of the sockets on the back of the unit, theyre sending me one, I ll post again when I get it.

Anyone have a idea if this would work with a joying head unit.

Dont know, ask the seller.
But in any case if it works with a Joyous unit it will work with ANY MTCB head unit. There is no such thing as a "Joying" head unit - Joying/CarJoying are simply re-sellers of Shenzhen Joyous head units.

Yes I think.
It looks made specifically for these HUs. So I supposed they tested them.
And screens look like built-in TPMS app that I got preinstaled on my HU (KGL). So I supposed it should work.
But I would preffer ecternal sensors, not ibternal ones. I have 4x4 which reqiires regular tire rotation and ibternal sensors are not suitable as I would need to remove and refit them on every tire rotation.
Is there external versio? I couldnt find it on AlliExpress.

The one I mentioned in my first post has valve mounted sensors and obviously works with MTCB head units

Why? Sure, if they are somehow hard coded to location its sort of funny when they might not match the picture, but you only have 4 tires. Its pretty easy to check them when they are low.
You want internal sensors for TPMS. Less chance for losing them.
http://www.ebay.com/itm/Cable-Bueto...Tire-Pressure-Monitoring-System-/271315933336

I understand the point about tire rotation and internal sensors. Would it be possible to make the same rotation in the app, since all sensors are doing the same thing anyway? Eg. If you rotate your right front to right rear, make the same in the app to correspond with the sensor location?

Yes, mapping is possible. Depends on product.

Hi All,
I have also interest for this. Somebody could give some information ? It works, or any other bluetooth type, using with external attached bluetooth 4.0 dongle ?

Well, I found out most of the connections for the TPMS as Klyde didnt send me a lead - power and ground were easy same as the DAB box, then, as its just a mini usb connection its just data + and data -, I know where the one of those wires goes, and narrowed it down to 2 pins for the other, I ve tried both pins and several versions of the TPMS app, but cant get anything. I ve tried looking for BT devices on my phone I thought I found 1 but my phone wouldnt connect and the headunit's BT wouldnt see it, my phone wouldnt connect and after removing all the batteries on the TPMS it still showed up so it couldnt be that. Totally stumped, just cant get it to work.

TPMS-Type
Let me inform you that for some time I'm trying to find a TPMS system that works well with Android auto MTCB-C I have made several purchases and placements from various vendors I will mention my experience to help future stakeholders.
For GS, KD, and JY machines, the following set works very well:
https://www.aliexpress.com/item/TPMS-for-SilverStrong-Android-CAR-DVD-Car-Tire-Pressure-Monitoring-System-4-Sensors-Alarm-Tire-Temperature/32803916037.html?spm=2114.13010608.0.0.IU13AC
It has its own very friendly app and it works with automatic start-up in the background and immediately informs if something goes wrong with the tires of the car, I recommend it for the above!
But last time I discovered another type with external valves that works very well with a Klyde machine and that's it:

Thanks for your post - I have the Last type, Klyde themselves supplied me with it, but they did not send me the lead and they did not reply to me when I asked for it, so I had to make one, but I still cannot get it to work, could you post a picture of the lead (the end that plugs into the head unit) so I can see which wires go where (I have seen the picture in your 3rd link before, but I cannot see where all the wires go) ?

Xtrons PF75ATTAR - a few minor issues... anyone experience anything like this?

A few weeks ago I ordered this unit direct from xtrons, and just tested in with a bench top power supply. It's running lollipop out of the box. This weekend I finally got around to installing it into my car. Everything works great, minus these issues:
There doesn't seem to be anyway to remove paired bluetooth devices. There's no gear cogs for each listing, and holding down on the device doesn't give you any options to remove or forget the device.
The Xtrons OBD2 dongle pairs with the head unit, and a blue OBD icon appears in the top status bar, but both Torque and Dashcommand see no OBD2 dongles.
When in the radio app, it will display the station and volume on my cars dash board (via canbus). But these messages don't always update, and get stuck with stale data - like after exiting radio app, whatever was last displayed will be stuck there. Also the volume adjusts don't update when I adjust them... it seems random... but when the radio app changes stations, it seems to work correctly.
Radio reception isn't as strong as my stock radio. Which is fine... it is what it is, but would be cool if it worked the same.
Steering Wheel app doesn't show any buttons to map/remap. Only shows save and reset. So I can't change any of the button functions....
Other than those things I'm pretty happy with it.
links to head unit for reference:
http://xtrons.com/pf75attar-7-inch-...-mirroring-function-obd2-for-audi-tt-mk2.html
http://www.ugsage.com/default/7-and...-mirroring-function-obd2-for-audi-tt-mk2.html

I figured out issue #2 after I did a factory reset. Before the reset, there was a list of about 6-7 mac addresses. after reset, there were just 2 (phone and OBD2 dongle), which made trial and error easier.. would be nice if it listed device name rather than mac address. Also, sometimes the list will be blank.. then only option is to close torque, or other app you use, then retry.
Also, grab one of these http://www.amazon.com/Electrical-Co...&redirect=true&ref_=oh_aui_detailpage_o00_s00 so you can use your car's build in GPS antenna (the shark fin on car's roof). Works good

Hi, thanks for the quick review, I bought the same and wanted to add some information as yours was helpful to me.
Bluetooth - same, I can't remove them from the list however, tapping them allows to "disconnect" them.
The only app I got to work with the OBD dongle from Xtrons was Torque Light. The pre-installed dashcommand did not work (I tried many times), also I'd like to use dash.by -- which also does not work unfortunatly.
With the radio, I have the same "problem" for the info area in the main dashboard. Some other apps (eg. CD player also seem to display stuff, but as I never use the radio, I don't really care. Would have been nice however to have the master volume displayed.
Radio reception seems okay to me. However, I loose the saved stations after restart. No problem, since I almost never use the radio and would invest in the DAB+ if I was.
Steering Wheel app -- same, I got the left part running with MTCD tools (here in the forums) to skip tracks. However, I can't remap the voice button and the mode button.
After updating the google app, the "voice search" feature is really slow.
Original shark fin GPS does seem to work fine with the adapter you linked, thanks!
Sound quality is way better than I thought it would be (eg. with Apple Music) as people wrote about low volume of rear speakers, hiss and noise. I only have minor static noise when nothing is playing and that is acceptable for me. Rear speakers are fine and the equalizer works great (put on loudness for warmer sound). (I have the nine speaker non-bose setup.)
Overall after a fresh boot or reset, the device is -- compared to eg. an iPhone 6 -- quite slow. Loading stuff (especially Maps) takes really long. Not sure why that is, but the device is way slower as you would expect from current Android or iOS hardware.
I am going to add if I found out more. Please do so, too -- especially if you find out someting about the steering wheel buttons.

did you guys figure out how to change the panel keys?
can get to them via extra settings and 123456, and can see them but seem to be unable to change or do anything to them ?

Android head unit choice for BMW e90 U.K

Hi Peeps
Really sorry if im in the wrong forum and im here to learn but hope someone can point me in teh correct direction
Im in the U.K and we dont seem to be able to buy Joying head units which seem to be popular in the states.
Im looking at Eonon or Xtrons mainly with the quad core processors and 5.1 Lollipop.
Is there anything i should be looking for or best avoided?
Thanks for any help, i really appreciate it.

Should be able to buy joying in UK they have a warehouse there try Amazon or eBay
Sent from my Nexus 7 using Tapatalk

Thanks, Ive done a search on Amazon and ebay for Joying e90 and get no results, ive also been on the carjoying u.k website and they dont even list the e90 as an available option

Buy from joying direct they will ship via dhl quick
Sent from my A0001 using Tapatalk

I have the xtrons e90 unit in my car. Seems similar to joying ect. One thing that took me ages to figure out as no instructions or guidance was given at all, was that there is two 12v yellow power leads and both need to be plugged in. One needs to go direct into the fusebox or to the battery.
Apparently BMW loses constant 12v power after a certain timer, roughly when the alarm system kicks in. So this means all power is lost to the head unit, including the small amount it needs to keep the MCU memory, which is your radio station presets and stuff. Also causing a much longer boot up. So I had to wire one of the cables into the central locking system fuse. Dead easy but you do need to buy a few bits from amazon for a few quid, otherwise the unit is a ballache.
Hope that helps

Cheers peeps, great advice. I've found auto pumpkin UK now so may order from them. The Xtrons , eonon and pumpkin all look identical so not sure if there is a difference as all seem to come from the same factory?
Should I be looking for the quad core 5.1 versions ?
Cheers all and thanks for the advise.
P.S I'll try and find the central locking fuse and use an add a circuit fuse to it.

I have just installed Erisin 3067B purchased directly from their website. It's a MTCD-based head unit. So far it is worth the price, although I had to struggle a bit to get everything working. In particular:
- The manual is almost useless. Moreover there are no installation details
- The head unit is very big and it is needed to move the AC controls in the lower part of the dashboard. I do not see how it is possible to add also the seats heating controls (I don't have them in my E91)
- Cable routing is easy. There are some videos on youtube regarding installation of Zenec car units. It took me 1h to get everything set
These are the problems I encountered:
- Quality of microphone, especially the external one, is very bad.
- The radio presets are lost every time I turn off the radio. No other settings are, therefore I guess it is software bug.
- exFAT is not recognized. So far I tried with a 64GB SDXC card and I only managed to read it when formatted as FAT32.

There are several empty positions in the fusebox. Do you suggest to wire the BATT+ wire directly or to install it with a 10A fuse?

you could do either apparently.
Personally i just purchased these, https://www.amazon.co.uk/gp/product/B01E3PQWUE/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1
and used one of them in the fuse for the central locking system, as it will always have 12v. Was really simple, tad fidly running the wire that's all.

I am having similar problems myself.
-BMW i-BUS it doesn't detect it at all. I need the CAN file for the unit, but no luck as of yet.
-Home button on the unit doesn't work anymore? Factory restore fix's but it stops again after 2 days!
-Most of the settings are locked from view. I access developer mode and it auto kicks me back to bluetooth phone menu.
- Front camera displays track and theres no option to remove it. So annoying!!
- LED colour APP has gone. This went after I did a MCU upgrade which I was given by seller.
- When I power up Clicker is always set to on. Front camera always resets to normal instead of saving mirroring. Other various settings are forgotten as are radio presets.
- Doesn't detect iPhone via USB only Bluetooth. But does charge... Slowly.
You had any luck with yours? I have a E90.

Hi. Try from AliExpress. Dhl or tnt etc 5 days is here. Yellow cable must ti be connected for the settings memory.

Help identifying unit

In my other cars, I have simple 2 DIN Android units which are easily identifiable and I have flashed different ROMS and MCU firmware to those to get the desired interface and features that I needed..
But with the new unit I purchased for my 2003 Mazda 6, I am having trouble working out what type of unit it is.. I have no idea if there are other ROMs available, or different MCU versions. I would like to figure this out, so I can potentially work on fixing some of the little annoyances that this unit has.
The unit was purchased from AliExpress here.
I have attached screenshots of the details in the settings app, and the 'car settings' app also.
Overall, the unit is very responsive, and the software isn't too bad.. but it has a few issues i'd like to attempt to fix.
Any help identifying it, or links to any MCU firmware or Android ROMs for it would be appreciated.
Thanks

The main issue I want to resolve, is the 'cold boot' each time I start the car..
Now, I have noticed that when turning off the car, the stereo backlight is turned off (yet the LCD is still on, and can be seen if there is light from the correct angle, and the touchscreen still works) and the stereo doesnt actually 'shutdown' until around 8-10 seconds later. This leads me to believe that its possible to configure the unit to not shutdown, but instead 'sleep'.
Would I be correct in assuming that the MCU is in control of the unit being sent the shutdown signal? Therefore, I would need a different MCU firmware to be able to achieve my goal?
I've seen lots of different MCU and ROM versions for other units, so surely there is some for this unit also.

I cant help you I m afraid, apart from telling you that they are deffo not MTCB/C or MTCD/E units.

As Typos1 has said, it's not an MTCx unit.
I did find some info here: http://4pda.ru/forum/lofiversion/index.php?t877165.html

Sorry for the late reply.. Im going through that post now (using Google Translate) but its hard to figure out what I need to do..

Start problems Android radio

Hi everyone, I don't know if I can share it here but I have a problem with my new Android radio.
First, radio works perfectly. I connected it so that it only works on contact. So key out is also radio off.
The problem is as follows: I open the doors and sit in the car. Put the car on contact and radio does NOT respond. Key out, doors locked. I wait until all the lights on the dashboard are off. I open the doors again with the remote control and put it on contact. Radio works perfect!!
I have never seen or heard something like this. Does anyone have experience with this? What is the reason for this? I still have another 12v cable that probably comes directly from the battery but I want to keep it original. If it is not possible otherwise, I have to use it.
My car is VW Passat 1.9 TDI from 2007.
Thank you all!!
Kindly regards,
Yusuf

What is headunit, OEM or Chinese aftermarket? What does seller suggest when contacted for support and has that been tried.
If chinese after market, wrong forum but post details from Android system information including MCU for post to be moved to appropriate forum.

Take the radio out and measure if you have 12V on the wire as soon as you put the car key to ignition.
By this you can check if it is a car problem or a headunit problem.
