See 2003/2006 FORD post I’m trying to get feed back on the edge product line from someone that has it; the new A2 with back-up wireless camera is what I’m looking at. It also has GPS. For the safety issues when backing, and checking what’s behind on the road and the GPS not as much as for the power, but that would be a nice extra feature. For the price you get the Camera, GPS by TOM TOM with preloaded U.S. maps and the power. It’s about the same price when you add it all together. As well as getting the back-up camera and GPS.
