Does anybody know why my USB/AUX port would not work?
I first tried plugging in a small USB hard drive (always worked with my old head units) and now I've tried a 16gb SanDisk Cruzer Force (just with 4 MP3 albums on it) and it always says something like 'no aux devices detected'
It's a CD400 head unit and the car is only 1 year old......and its super annoying
