Aftermarket head unit install questions (W210 E320)
I would like to change the head unit in a W210 1998 E320 to a JVC KD-R900. Is there an adapter that will not require me to splice the wires so I can return to the factory head unit anytime?
What else will I need besides the head unit to make this install look professional? I don't have Bose in the vehicle.
