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?

 

No one?!

 

Post this in the 997 section you might get more help there.
