I have bought a gizmo that piggybacks into the back of the professional radio and gives me usb and phono. That's all fine, but how do I thread it through the trim to sit in the passenger footwell? What's involved, don't want to take the dash out or any old nonsense like that. So...?
Any sparky type people near me in Burton?
