Is there a way to get sync or bt capabilities on an 07 or 08 model yr truck. Can the dealer install them onto the truck? Could you buy a sync capable head unit and the bt module and assmble them together. I ask because i found an 08 im interested in and since those models dont have usb ports, id like to add the bt to it without getting an aftermarket. I dont wanna have to retune the sound system which is pretty damn good.
