I have recently bought a 270ML (used). The TV doesn't work and displays the message "NO TV". As I have never had a car with a TV (and the person I bought the car from has yet to find the user manual!) I am at a loss as to how it works. I assume I need to purchase something to get the TV to work but have no idea what.. can anyone advise please? Also, the car has a bracket for a nokia phone but I have no idea what phone that is. If anyone knows I'd be grateful!
