Kirt,
Bought my 07 in July and so far I have had it in to the dealer 2 times just for the radio and it's still dosen't work all the time. Mine cuts out, sometimes goes dead, sometimes it fades in and out all by itself, sometimes just by turning the vol knob it will come back. Dealer has been good about it but I'm gonna make them put in a new one when I can get it to them. They have already tried the grease in the connectors without results.
