I went to some trouble to fit a reverse camera for my AVC9000-1. It worked fine (am waiting for a better camera installation). But I was surprised how useless it was in practice. You listen to the reversing beeps, look in the mirrors and all around you, but never down on the dash somewhere. It impresses the passengers, and looks the part, but actually you don't look at it. Bear this in mind before you spend $500 upgrading your system.
