Hi,
thank you very much.Sorry,I don't speak english very well because i am french,so i try.

Can you explain what is the MID ???

On the aftermarket Jvc system,there are input video(Perhaps may display numbers and such???) and input audio (Perhaps get the audio???).
In the set menu there's "phone muting".

1000 thanks

Ps: I connect the Jvc system into the car with an ISO cable,so all the items(BT and cable)are still in the car.
I don't cut any original cable or connecter!
