Carkit / Navigation / Radio Mute

Hello friends.
Long time after planning to build my own Car Kit, at least i orderd yesterday an original Car Kit from O2.... :roll:
Not having received it, i´ve got some questions about it. ....
I´d like to connect a GPS mouse to it and will use my TomTom-Software with it.
Wiring the GPS should not be a problem since FVH did such great reverse Engineering... (Thanks a lot for it)
My Question is now about Radio Mute / Speaker output....
I´ve got 2 input Systems at my Radio. one for Telephone and one for NavigationSystem....
Where do i connect the car kit now? I think, i can do only once of it, or?
What will happen, when i use the mute-connector for phone on radio-side? Will it stop the Radio on every output of the Tomtom? Will it only mute the radio when a call comes in?
What are you´re experiences?
Glad about every answer....
Regards
Stefan

Come on guys....
Where are your answers?
I know there are some people using the Car KIt, and i think they use the Navigation function too....
So plz geave me some tips....
Regards
Stefan

Yes,
Also using the XDA carkit. I found the radio mute function very disappointing: it is triggered by a variety of events (screen tapping, navigation output, GSM basestation handover etc). Finally decided not to connect the radio mute to the car stereo.
If you have a line in port on your radio/cd, you can profit from good quality mp3 from the xda without using the mute cable. Also connect the carkit speaker, parallel to the line-in.

Radio mute
I have taken a closer look at how the radio mute works. It quiet easy, if what ever signal (beep, voice, music or what ever) is sent to the XDA speaker, it will trigger the mute signal.
The mute wire is pulled to either ground or VCC (i can´t remember which one, it´s been to long...) as long as there is audio output. When connecting it to my radio (Renault Laguna) I found it works the opposit to what you would expect: no signal--> no radio ; voice or telephone --> radio on.
SOlving this is easy, just get a small relay (make sure it power usage is low, specs can be found in the Carkit manual) and connect it to the mute signal. Use the switched contact to create an inverted signal.
Good luck,
Francois

The mute wire is also pulled as long the GPS Software of TOMTOM is active.
Any idea how to fix it?

In my case this isn´t so.
Mute turns on, when audio ouptut is from Tomtom or anything else. After this, it turns on Radio again.

GPS Software of TomTom switches Mute
I also have the same problem:
As soon as the GPS Add-On of TomTom starts, Mute of the O2 Car Kit is switched and the radio keeps silent until the GPS Add-On is terminated.
Any idea how to solve this???
Thanx,
Charlie

Looks like a faulty carkit.
I do see the problems as described, mute works correctly, even when navigating.
MAYBE this is your problem:
----------------------------------
When I put the XDA in the cradle and the GPS is switched on it looks like that the amplifier is switched on. You can hear this by listening to the noise that produced. It sounds a lot like RS-232 interferance.
I solved this by pressing the RED phone switch once or twice until you hear a beep comming from the XDA. This first legitemate sound correctly mutes the amplifier and from that moment on the carkit works like it should.
Try it and let me know,

TomTom7 and Car Holder -No Sound!!?

Hi all!
I have TomTom7 installed which is working fine (almost).
When I place my Diamond in the car holder (three way output w. USB-Charge/USB-Headphones/3,5mm Headphone) all sounds from my phone are muted (believed to be connected to a headphone I guess).
I could connect the phone to the car audio system via a 3,5 mm audio plug, but then I cannot listen to the radio at the same time as navigating with TomTom.
Is there any known way to solve this so the TomTom7 directions and warnings are always routed through the Diamond internal speaker?

i have this carholder too, it's from brodit right? It's true, the moment you plug in the diamond it thinks it's connected to a headset, so no sound from internal speaker. Ideal for listening to music when connected to your car stereo ofcourse, but when receiving a call you have to take out the diamond, because the sound goes through the car speakers (if the output is connected to your car stereo ofcourse) but you can't talk back because diamonds mic is also muted! I hope there is a way to solve this. Maybe a little program that allows you to direct sound and mic settings?

It's also a similar problem with the little USB to 3.5mm audio adapters, they make the diamond think there is a mic plugged in when there isn't and when someone calls you while you're listening to music, they cant hear you unless you unplug the headphones.
I've also noticed that when the diamond is in my car and connected to my bluetooth kit, the calls come via bluetooth but TomTom does not, this particularly annoys me, as when I'm listening to loud music I miss the speed camera alerts and also obviously cant hear the voice directions.
There seem to be some fairly serious shortcomings in this area. A simple set of options that let the user choose what he/she likes would be best.

Yepp Glenner, it is a Brodit car holder!
A program to solve this as you mention would be great!
Anyone got the skills to solve this?

Yesterday driving home from my work I noticed that the ring tone on an incoming call was heard even when the phone was placed in the holder...
So there must be a way to have the sound re-directed to the internal speaker???

Solved!
Try this little program http://www.freewarepocketpc.net/ppc-download-btmusic.html It sends audio from you diamond to either BT headphone or speaker. Just tried it and seems to work fine, but does need .netCF 2.
Best of luck!

Hi, this BT music doesn't seem to work with my car kit... My car kit supports HFP profile (Handsfree profile)...
What did you do exactly to make it work?

if you rename btmusic.exe.config (not btmusic.exe!!) you can run it too with .NET CF 3.5
Trick i learned from the developer of BTMusic.

Rename to what?
I figured it out. Renaming btmusic.exe.config to btmusic.exe.configx does it.

Diamond - using in-car, few issues...

Hi All,
I'm wanting to use my Diamond in the car to replace both my old iPod and sat-nav, while still having phone functions available. There are a few things I'm not happy with, so I thought I see what other people are doing.
I have a car head unit with a direct 3.5mm line-in, which used to have the iPod on the end. The Diamond works fine plugged into this through an ebay 3.5mm\USB adaptor.
If I plug the 12v>USB charger in, I get a whine over the audio - not a big problem, it's just a ground-loop, so I'll stick an isolating transformer in-line.
The main problem I have is switching between the internal speaker and the external output. If I want to have the radio on, rather than MP3, I have to unplug the adaptor, and plug the charging cable in direct, so that I can keep the battery charged - not ideal. This way I can hear the TomTom voices through the internal speaker, but it seems wrong to have to swap leads this way.
The other main problem is if I have MP3 and TomTom all through the stereo, and I get a call, I can hear the call over the stereo, but can't speak, as the Diamond is expecting an external microphone.
I guess what I need is a utility to force only the internal microphone to be used, and to allow me to force the internal speaker when I want to use the radio. It there such a thing?

I think one of these car holders has an option to plug in charger and usb-3.5mm jack adapter at the same time....
http://www.dsldevelopments.com/brodit/Holder/HTC+Touch Diamond-Brodit-Holder.asp
If i had the skills i'd try to figure out a hack to pause/mute the mp3 and mute satnav when in a call... but I don't.

That's not the problem - I can plug in the charger and 3.5mm audio at the some time, but that redirects all the audio to the car stereo, and disconnects the mic. Removing the adaptor and plugging in just the charger enables the microphone, but all my MP3s then are played through the internal speaker.
What I need is a utility to force the internal microphone to be used _all_ the time, and let me choose when to use the internal speaker when a headset is detected.

I don't suppose anyone knows how the Diamond recognises a headset? Is there a resistor link across a couple of the pins in the 11pin connnector? I'm just thinking I could make up a cable with a switch to break that contact, and 'virtually' disconnect the headset when I want the radio, or need the microphone active during a call.

You could try this program. It seems to be a virtual switch between the earpiece and external speaker. I use it a a solution for skype and other voip programs that only work through the external speaker, but the works the other way as well.

headset instaled but need phone mic allways enable

I have the same issue of kaisee.
I use the diamond as mp3 player in my car stereo (aux-in) and i need the mic allways available to use the phone without disconect the usb or audio plug.
In my old magician this worked just fine becouse the mic was allways available.
Is the .exe posted by dctech the answer(thanks man) ? has anybody tested ? is it reliable or there is another solution?
Thanks

You need a proper bluetooth car kit to allow this. Parrot ones are very good. If you want to listen to music as well as phone calls and sat nav i would suggest that you get one with both handset and A2DP bluetooth profiles. There is a workaround app you can use to get music through a car kit with just a handset or headset profile but the quality is mono and very poor

Headphones with 750

What headphones do you guys use with your Treo 750?
At first, I just bought a 2.5mm to 3.5mm adapter and used any set of headphones but then became to cumbersome having to always unplug it to answer phone calls (especially in the cold).
So then I bought the Body Glove headphones with the 2.5mm jack but found out that only the right headphone works because the other signal is used for the mic! BUMMER!!!
So now, I'm to looking for another set of headphones that will work on the Treo 750. I want both right and left headphones to work and also have a working mic on it!
I might just get a bluetooth stereo headset and never have to worry about anything! But I just wanted to know what everyone else was using...
Thanks!

i bought a headset that had a 2.5 - 3.5 mm adapter and on the adapter itself was a button for switching b/w phone calls.
the other end was basically a jack for using any standard headphnes. so im some some sick in-ear ones taht have amazing bass (most of the regular phone headsets have sh!tty bass)
i would go w/ bluetooth but i dont know how much of a drain on battery they'd be. plus $$$.

I use an adapter from 2.5 to 3.5 and use a Creative headphones in order to listen music, sound is very good, but have no microphone, I'm thinking to buy a 2.5 headphone w/ mic, in my opinion a good brand should be the correct option, maybe somebody could tell us their experience.

Speech Quality with Headset/Car Stereo

I don't really know how to explain...
I use my Nexus one in my car for calls.
I use a jack cable which is plugged into the radio. So I can hear my partner over the speaker in the car. Very good.
But, the others can't understand me. It's crappling all over.
When I put the cable out of the jack and use the normal hands free on the phone, everything is fine and the others understand me very well.
By plugging into the car radios jack, it starts with crappling my voice again.
Does anybody have the same problem? Or is it fine on your Nexus all the time?

sounds like the phone might be trying to find a microphone in the radio

Yes, could be. But why? What can I do?
It was very cool when somebody can try it, if it works on other NexusOne.

well the default headphones had a speaker in them so the jack is made to work as a speaker jack and a mic jack. however im not sure why it is expecting a mic when there is no information being sent back to the phone.

Simple expanation, I think - noise canceling functions.
When you're in speaker mode, it's settings are probably changed to account for a voice coming from a distance and being roughly equal for both mics, while when in regular mode it's working and expecting significant signal difference. When it doesn't get it - since you're speaking from a distance - it doesn't "think" you're talking, and cancels your voice partially as it would cancel outside noise.
There is a hack somewhere in General or Dev section, how to disable noise canceling. You might try.

OK, when I find it.... Sounds good
