garbled screen

I would suspect that the digital screen issue you are having with the radio in your 2001 BMW 330ci is due to an internal radio fault. The radio will most likely need to be replaced or sent out for repair to a shop specializing in those type of radio repairs.

Its probabably junked, got wet or something, go to BMRparts.com they will have a radio to fit your car, for under 200.00 used , and a host of other parts . on line salvage yard Dave
