The other day my Defi setup and my kenwood nav unit both went out... I took everything apart and found out that one of the wires for the defi system was loose... I fixed the loose wire and the defi and kenwood both work now... The only problem is that the defi system and the head unit don't shut off when the key is out of the ignition... Its like they are connected straight to the battery... I looked at all the other wires and everything looks fine... Maybe the wiring is messed up on the defi? I dont know... Does someone have a picture of the wiring of theirs? Any other possibilities?
