There are NO parts in the US for this radio,,,,,Pontiac is waiting for radios from Germany,,,,at least my dealer didn't tell me 4-6 weeks like some,,,it will be much longer!! It turns out the A/c control/Panel/Rear Window defogger dead was all a very bad connection;;Service Mgr said these are very poorly assembled. My Dash only shows 3/4 of the number on display,,,this too will be months in coming.....They once again refused to bleed brakes, so will have it done at a shop and pay,,,in a few months when I get a radio(or years) I will insist they adjust the em brake,,,tiime to get tough I guess..I emailed pontiac;;they promised a response in 24 hours on time frame for radio,,,,stilll waiting??
