ok so still having problems.
before my cd player was hooked up with all the speaker wires goin to the speakers and the red wire connected to the red. red is ignition i think? i forget what it says. and then i have the yellow wire(12v constant) tapped into the cig lighter. with this setup everything works, it turns on wit the car, but it will not save my settings. so i tapped the red wire into the cig lighter and connected the yellow to the yellow, by the way i have the wiring harness that connects to stock, but after i switched these two wires i figured it would work but this time the cd player would not even come on. i checked the fuse and it was ok. i put it back to the way i had it and its working again just not saving settings. any ideas?
