What would I need to install this inside my car? It has an auto dimming feature with map lights on the bottom and it tells you the outside temperature. I know power would have to be wired up to it some how but what about the outside temperature reading? If anyone has ever put one of these in their car can you post a DIY or list steps taken to make it work?
