I have seenan olderpost on this but it went no where to help me. My 04 Endeavour has the 6CD integrated. All I want to do is integrate my GPS Stereo output through the vehicle speakers.

I don't particularlty care ifI have to splice into the harness or use an antenna in line FM modulator. The goalis to be able to provide a 2.5mm input plug for my stereo output from my GPS unit therby providing MP3 playback and cellphone handsfree with the Bluetooth between my Cell & GPS.

Someone must have done this. PLEASE Help!
