I have some trouble with my Jensen VM 9512. When listening to FM radio, on some channels I hear (kinda buzzing) noises, that shouldn't be there. The car is a Ford Focus MK1. The original head unit works fine. It isn't audible on all stations, just a few. Music from CD/DVD and SD works fine. Any ideas? There is one more question: There is an Audiovox VME 9512 TS sold in Europe. It seems to be identical equal to Jensen 9512. But there a some reports that that unit also plays video files from usb and SD. Any chance of getting it done on the Jensen aswell?
