Hi Folks: I have a real nice mirror with compass. Bought it for my Gen III but I found a homelink mirror instead. Easy installation. 3 Wires. Ground, Acc. 12 Volts and constant 12 Volts. The other wires were used for the outside temp module. $50 shipped. Thanks, Don Naples Florida
Yes....I think all the Compass and Homelink mirrors are auto dim, but I haven't tested the auto dim feature. Don
