Hi
Does anyone know how to set this radio back to a default code? or know how to remove the code.?
when i power up the radio all i get is " - - - - " on the display. it did at on time show CODE
And one last thing what do each of the wires do ? I've sussed Red and Black and i think the yellow one is the memory, but not sure on the orange & blue one. Also which speaker wires are which i.e left front right front etc.

thanks
