i was wondering the same thing.. and pretty much came to the conclusion that after talking to some guys at the dealer, that if i want a aux jack added, best thing would just be getting a new head unit altogether and just lose all the temp, mileage, etc options on it unless you feel like paying a minimum of 400-600 dollars on one of the newer 08 g6 head units.
I'm real stuck, i find the temp gauge and trip mileage especially helpful but not having an aux jack kills me.. my FM transmitter is terrible as they all are unless you use it when your not moving around..
