I just got a budget $200 install for my AVIC-D3 and I got what I paid for, as the system has a hell of a lot of engine noise.
Anyway, I'm planning on taking it to a good installer to get it rewired, but I won't have time for a week, so I want to know how do you turn the AVIC-D3 off. If I mute it I still hear the alternator whine, so I want to power the whole thing off till I can get it fixed.
