Hi, As I understand it, there are a set of easy steps you cand do to enable it. You should try using the google search engine to search this board. Someone posted the proceedure last week I believe. You may also want to post again during the week when more people read the board. Basicly, you need to get into service mode, select the contrast setting mode, hold down the knob while on contrast, and then turn off the igniition while holding the knob in. Then you need to turn the ignition back on within 8-10 seconds. The timing is important. Once you get the timing right the TV will work from then on. In other words you don't have to keep doing this. Onece you get it enabled it will stay that way. Good luck, Laura I just recently purchased a 98 740i w/ the built-in navigation system which appears to have a television option. I can get sound for TV stations but no video? Any ideas?
