This is a new bluetooth car kit from Motorola. It has thye ability to integrate with audio systems. Does anyone know if it will work in a Cayenne?

 

It's got an interface to mute the stereo upon incoming call and wiring for speakerphone. I doubt it'll work with MOST.

Saw a Bluetooth kit at Brookstone with spkr, mic, module all built in for $150. It can be battery operated or wired to cig adaptor.
It can clip to visor or mounted to dash or windshield. I may try to mount it to the seat back so wires don't hang out.

 

I just had the Sony Ericsson HCB-30 installed in my car. Got the phone mute kit from Becker. Works perfectly. call comes in and mutes the radio then plays through the speakers.. everyone says the sound quality is perfect.

 

Parrot 3000/3100 kit will install, any phone.
