Hi guys! Well, yesterday all the lights in my radio/navigation went out. My navigation light does not dim if I turn on my headlights and I have to adjust it manually. Also when I unlock/lock on my keyfob my headlights do not flash either. I'm sure it's something to do with the electrical wires but does someone have the same issue? My navigation was installed so I think that might be the problem but lately I can't even zoom out unless i do some weird things to it. anyways just wanted to share with you guys my problem.
