I bought my 2008 g6 in march, and the auxillary outlet for my ipod has been acting up. it never really worked right since i got it. it either doesnt switch over to the auxillary when i hit the source button or it works for about 30 seconds then switches back to radio or cd...i brought it to the dealership but they said they had no way of testing it. any idea of what i should do? thanks!
