Re: Homelink (Itgb)

The HomeLink unit requires just +12v and ground. Both of these are already in the visor to power the mirror vanity lamps. They are on the same fuse/circuit in cars that are equipped with HomeLink from the factory. There is no software download required other than what you must do as a user when learning rolling codes.

In regard to extending the range, it might be easier to consider extending the range on the receiver, which is on the garage door unit. Make sure there is an antenna wire attached, it is not blocked by metal objects etc.
