So long story short, I removed my aftermarket Panasonic deck and Polk speakers (they're for sale if anyone cares, and they're nice
) and reinstalled the stock stuff. Crutchfield made installation a breeze since everything was plug and play, so the aftermarket stuff just unplugged and the stock stuff just plugged back in. Now here's the issue, the stock head unit is wigging out. The display flashes with no apparent pattern/consistency, the sound travels from speaker to speaker, the controls/buttons don't work other than the power/volume. I can't figure it out. Is the stereo dead? Any suggestions?
Thanks in advance.
