Hello everyone. I have just purchased a 2005 CTT. I haven't seen the car yet and it is still in NoCal waiting to be shipped to my location. In the meantime, I've been doing research on the things I want it to have. iPod integration and Bluetooth is something I want done as soon as I get the vehicle. I've been reading stuff here and I am now very confused. Please excuse a Cayenne newbie but what is PCM 2.0, 3.0? Is this the software version? For a 2005 CTT with navigation but without phone buttons, which PCM does my car have? I've already corresponded with Eric of bumperplugs and he had mentioned that BT integration won't work if the PCM does not have the phone buttons and my car doesn't seem to have them. I've read about Parrot somewhere here but when I checked Crutchfield, they do not have any kits that could integrate Parrot bluetooth with the PCM (unless I use an external Parrot speaker which would suck in such a nice interior), therefore, I don't know if anyone had done any splicing work just to have Parrot BT in the car. Had tried stand-alone BT kits......hated them. Don't like BT earsets......constantly gives me headaches. I just want BT with microphone attached with voice coming out of the car's speakers. Any other options you can suggest? Attached is a pic of my CTT's PCM. Thanks for any help.
