I have a Jensen VM9412, hooked it up, it'll beep but not come on...any suggestions?
a few more details please. What harness (if any), how did you power it, hows it grounded, twist and tape the wires, or did you solder/heatshrink them like you should have and so on and so forth.
Did you see if the fuse was in the holder? sometimes radio companies they slack off with that..
I'm gonna say that you wired it into the factory harness. You have a 2002, so the wire that would be the accessory is not an accessory wire at all, it is a data wire. If you take that connection and wire it to say..... your windshield wipers instead you should be golden???
did you read this?
