Use phone mic with bluetooth headphone

[fabolousv]

Hello all i paired my carkit to my n900.works all fine but the microphone of the my car radio is very bad so i want to use the phone mic instead. so i modified etc/bluetooth/audio.conf and i added this line:
Disable=Headset

now my n900 sees my carkit as a bluetooth headphone. which is what i wanted . but now when i receive a call it uses the phone speaker and phone mic and not my car speakers.

does any1 know how i can fix this?

[amorek13]

i am no coder but it seems like to disable all the features of the headset

It should work cause mp3 does work.
so the voice should go throught the phone mic and the audio to my radio with a2dp

Does anyone know if you connect a bluetooth headphone to your n900 and you receive a call you can hear the audio through the bt headphone??

This is a little off topic but does the same go for a wired headphone? Im assuming the headphone jack is multi-function, as in will carry both the mic and stereo audio, so if you plug in just a stereo audio cable that the mic will continue to be used off the phone? The reason I ask is that I have a similar setup in my car but no bluetooth. I have an ipod adapter that syncs up to my stereo and has a line in for aux input. If I could plug into that and get audio out the car speakers and continue to use the mic on the phone thatd be awesome. Im assuming there will be echo / feedback depending on how well the phone mic noise cancells.

egrims what you want does work thats the set-up i use now.
