997 XM Retrofit Weird Behavior


Recommended Posts

Ok, got the XM installed fine and it works... mostly. About 35% of the time, I start the car and the radio is on the last station but my channel list is empty, it doesn't display the current channel info, and I cannot change stations! If I take the key out for 15-20 seconds and restart the car, all work as normal.

Also, if I hit Main + Trip to pull up PCM versions, it has a triangle with "!" next to satellite. Dealer hooked it up to PIWIS today. It said said bad module for sat, but tech said that was fine since the Cayenne kit wasn't made for 997. Ultimate advice was "Sorry, probably software bug. Live with it."

Any ideas?

I know this thread has been around for a while, but i have a question on which Cayenne kit you installed, there is a kit for a Cayenne with a cd changer - 95504490268, and another for the Cayenne without a cd changer - 95504490267. the reason i ask it that i want to put xm into my 2006 - 987 Cayman. and i'm not sure if there is a better option than the Cayenne kit.

many thanks

scott
