2008 Vito W639 Radio wiring diagram
I can not get ANY speakers working. The new radio has 2 wires out the back of the unit for + Pos and - Neg
for each speaker ( left front and rear and Right front and rear) That's 8 wires for speakers.
I have wired in a separate speaker and it works but the genuine MB speaker do not work
Where do I find a wiring diagram for the radio??
