Installation was easy enough. You need to know how to follow your car's wiring diagram to find the right wires to power every aspect of the device. The Next button works, so make sure it's set correctly. Update: not sure what happened but the watch completely caught fire. It won't even glow. It was an expensive, short-lived toy. If you buy one, install fuses on all lines, even if you have a main fuse box.
