Installed a dash cam in the 570. Tapped the auto dimming mirror for power. I have the same setup in the 100 which I have been using for the past 4 months which works fine. Bought the parts from Amazon: camera, 12v to 5v converter, and memory card. From the mirror the left wire, white with black stripe is negative while the green wire all the way to the right, is positive. Can also use these wires to tap for a radar detector.
