But, before i go spending my readies on a nice unit can someone explain these things for me please?
There are ISO connectors behind the ciggy lighter assembly as i've got my Rover bluetooth plugged into it, so...
Buying a chinese double din, will the steering wheel controls work? I also have spotted a blue/green/yellow connector block floating around behind the dash with a single wire going to it. Would this be anything to do with the stereo?
And with the ISO connectors, is it literally the BMW loom that plugs into this, thus disconnecting it isolates all the sub/amp system, and will speakers work ok without it all?
