Hi All. well I just picked up a 2009 G8 GT with Factory Blaupunkt and I have a strange problem.
I have no front door speak sound (Left or Right), do have center, and I have rear Pass speaker with sound. Rear subs seem to work fine.
I have played around with balance, fader,etc and no no sound. I am wondering if anyone repairs these factory head units. I was always happy with my 2006 GTO radio and expect this one will be better, once I fix it.
Thanks everyone. Today I started pulling speakers and you guys were right.....corroded wires at the door speakers. Got a nice surprise that previous owner upgraded to Polk so I can send back the $250 worth of speakers I just bought.
