OK, I went to the dealership to have them remove the OEM radio and I purchased a wiring harness for my aftermarket CD player. Now everything has been wired up properly according to the harness schematic, and my CD player schematic. The CD player turns on according to the ignition position which is good, and everything seems to be working fine with one minor problem. No sound comes out of the speakers. ANY IDEAS??? Is there some sort of OEM amp that I need to wire into??
