I installed a mobile rig in my Camry many years ago, but it never really worked right so I took it out. Now I’d really like to put it back in, but I would prefer to find a professional who can help me properly wire and set up the radio inside the car. Would anyone know of a directory of companies or businesses that specialize in this sort of work? For reference I live just outside of Washington DC and heard there was a business here that could do that kind of wiring, but unfortunately I’ve reached a debt in with my search. thank you !
