You have to hook up the "ANT." wire or the "REMOTE" wire it should be BLUE. If you used a harness to do this you should have got it right. Unless you got a cheap radio and it don't have either of those I've never seen that but I'm sure the exist. If you have both wires, hook it up to the ANT. wire because that one will only raise the ant. only when you turn on the radio and not the cd player. If you only have one blue wire then that is the wire that you need to use BUT your ant will stay up as long as the head unit is on radio/cd/whatever. That sucks because the ant. is f%&*ing ugly.
