hopefully some one can help as i am going blind with all the pages i have looked at on the web🙈.
i have just retro fitted a phone and bluetooth models to my s type. it originally came with sat nav and voice and pre wired for everything else.
i initialy installed the phone and bluetooth modules and had a message on the screen saying phone in use hang up, after a bit of surfing i found that i had to do some re-wiring, sorted no message phone book downloaded and can make calls.
This is where i am stuck, i can hear the other person but they cant hear me. by what i can find on the web this has been discussed on loads of sites but it is always with people retro fitting with no voice and then cutting/joining wires.
i have the built in microphone in the roof not the external mic. voice works no problem.
can any one help as i am really struggling.
