Daughters car has the standard stereo fitted with single c/d and radio with steering wheel controls. it is busted,has the wait word in the screen all the time,not resetting. She wants to fit a new one with bluetooth etc and has the surround on order to do this. We removed it this morning to see what wiring it has and there are two sets of green and yellow connectors that i assume connect the steering wheel to the stereo? Are there any cables or gadgets to allow a standard din stereo to connect to this wiring and still retain the standard steering wheel connectors? If not is it possible to buy a used working standard unit that can be used with an aux in so she can connect her i phone to stream music? Thanks Emilys dad.
