After market remote mirror controls using bluetooth. I love my 1999 Ford F-250 Crew Cab, but the mirrors are a bit difficult. Over time i find myself wishing there was a way to replace my manual mirrors with electronic controlled mirrors. Wheneveve I mention this to my dealer two words arise cost and degree of difficulty. I f the mirror housing could hold the bluetooth receiver and power supply (battery) and the transmitter could be mounted anywhere on the drivers side.
