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....

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?

Click to expand...
Click to collapse
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,

Hello, my question is whether you can listen to FM radio without plugging headphones and plugged a cable-miniUSB usb without more.
The HTC P3300 doing this works simply a change in registration
You should go to the next branch of the registry:
HKLM / System / State / Hardware
And the key change "Headset" putting the value 1.
In the diamond I have now tested and active radio stations even caught but was not heard by the speaker is something that needs to be altered more in the diamond. Some who controls to see if it knows what to play.
Thanks
Maybe you can force the radio application to work without headphones but since the headphones are the FM antenna reception could be very poor.
i have a tiny adaptor i got from ebay which changes the mini usb to standard 3.5mm headphone jack.
since just having the adaptor in the phone without headphones plugged into the adaptor makes the diamond think theres a headset attached, i tried to open the FM radio and it would open (does not ask you to insert headset) but cannot pick up any stations as the headphones are the antenna!
so really your request is pointess as if you could get the FM radio to open without headphones plugged in, you wouldnt be able to listen to anything!
Can anyone help .
How to bypass FM radio to check for earphone jack as anthena
Kind of annoying always need to plug ear piece to listen to radio
No way to bypass, since you need an antenna for receiving FM transmission, and the ear piece cable acts as that antenna....
Silicon Labs has made a chip with an integrated antenna - but it will be released or better be integrated in the future, that means in upcoming and the hd following devices.
Hi all,
I am considering using my HD2 instead of my radio in the car, just having the output via an amp to the speakers. The one bit that is missing in my mind is a decent aerial connection for the phone, has anyone worked out a way to improve reception for the FM radio or how the aerial works.
I must admit I am not to sure whether the mic input will work as there may not be any noise cancelling on the input from the the jack...
Any ideas?
I will be ripping apart my headset to try and work out the buttons, unless somebody knows where to find any info on how they work..
Hi,
I understand that in order to have the FM Radio working we need to have the headphone plug in because they act as the antenna and as such bluetooth does not work.
My question however is different in nature, If I plug in the jack a cable (headphone cable without the ear part), is it possible to have Tasker replicate/duplicate the output of the earphone jack to a Bluetooth headphone? This way, there would still be a cable to act as an antenna and we could listen to radio without the hassle of cable.
I tried to find if this question was posted elsewhere without any luck.
Thanks for your help.
