I have a 2003 330ci with MKIV navigation unit with DVD. The screen has recently started flickering, basically a dark screen with some random flashes. After a while, the screen just works fine. Sometimes, it works perfectly fine when I start off and it will start flickering again and stop. Its just really random. Everytime it comes back on again, it seems like it just reset and the initial T 20.1 screen comes up. Has anyone had a similar problem? I currently don't have warranty on the car and wanted to ask around before I took it to the dealer.

Thanks in advance!
