Just got my Cayenne GTS back from the shop slight cosmetic repair from a wife's "ops" two new rear tires (20,000 including towing a trailer) oil change AND the instalation of the Mobridge bluetooth and ipod interface with the Porsche nav system. I have not tried the ipod adapter but the bluetooth quickly paired with bot my Iphone and my wife's. Tried it on the 50 mile trip home and it was seemless and the bluetooth audio both on transmit and receive was excellent. Had the install done at my local Porsche Center and they did a very professional job. I'm a happy camper and look forward to our next trip in the Cayenne.
