We bought a 2008 Acadia last Wednesday evening. They told us there was a disc stuck in the CD/DVD player. When we got it home, and he couldn't get it to eject, my husband immediately used long tweezers to pull the disc out. Then the screen kept flashing disc error and would not accept a disc at all. The next day the car wouldn't start, battery was completely dead. Once we jumped it it charged right up, thought maybe we had left a light on or something. Next day, same thing, dead. Battery was tested, it was fine, the alternator was fine. Hubby was pretty sure it was the instrument panel, because the little display for the odometer and such comes and goes (they also told us this). We also thought we probably got sold a major lemon. I kept coming back to the radio/cd player. So last night he pulled the radio fuse to check that first, and lo and behold the car starts right up today. So he's looking at replacement radios, but is there anything we can try before resorting to that? Some sort of reset? He's a mechanic, so he can do the replacement himself if needed, but I thought I'd do some research into options myself.
