Hi everyone,
Retrofitted a tv tuner today and when I turn the ignition on the nav screen is just blank. It then goes a lilttle crazy with lines jumping all over the screen. Can't get any menu's up. The screen just keeps jumping with lines all over it. The tuner I picked up is a phillips tuner and I am not sure if this is not compatible with my 2004 screen. I think the tuner is 4:3. Can someone please shed some light on this for me. Bought my tuner harness from Bimmernav and the tuner from ebay. Any help would be greatly appreciated.
