Help! Shortly after I purchased my 2000 Civic Si, I installed the head unit from my previous car, a Pioneer DEH-P8000R. I did an excellent install job w/ a harness and have had no probs since then but now after about 4 years that stereo has started to crap out on me. The unit still works but the buttons are worn and the automated displays is gone. That's understandable, it's four years old. My problem is now I'm attempting to put my factory head unit back in until I can afford another pricey system and I'm coming up scratching my head. This should just be a plug and play but I'm not getting any power to the unit at all. Fuse is ok, wiring is definitely ok, everything was reinstalled the same it was when I bought the car brand new. After fumbling around w/ ideas for a day or two I removed the system again and tried to put the Pioneer back in and it won't work at all now. This leads me to believe it's an electrical problem but where??? Any help would be great.
I should add that when I first plugged the factory unit back in, the "Theft LED" began to blink red indicating that it was getting some power. I knew I was gonna have to enter the security code if I powered the unit on so I didn't bother but rather finished the installation and put the dash panels back on. Sometime during that process the light stopped blinking and it never has since then.
Hey Jason, why don't you get a meter and measure the power wires? If there's no power, then maybe the fuse blew? Check your fuse panel, and look for car radio. I can't believe they actually put theft code on cheap HU. I mean the stock radios are worth no more than $50. I think it's a waste of time.
Hey Jason, if the engine is on, there should be power there. I think there's another fuse for that wire, not 100% sure. Check your owners manual for the location. If you have an external power supply, connect it to the HU's power and remote wire. If it turns on then you know HU is okay. Since you're getting powero on your main wires, that's some good news.
