I put in a D3 in my Saab a couple of months ago, but was too lazy to hook up my Seimens Bluetooth kit when i was doing the initital install, so I plan on opening it back up and doing it this weekend.
With the stock head unit the radio had a mute connection, as well as two wires for the audio input, and during the call the radio would mute and display "telephone", while piping through the audio from the kit. Is there any way for me to do that on the D3? I know that there's the mute wire that will kill the audio, but how I go about dealing with the sound?
