The TV & DVD is working only if car is stop ?

The Columbus support any video file ? (avi or something else)

If yes ..this is can play when the car is moving ?

I get my car in 90 days..So I have some Q ..? :)

The only video the columbus plays is DVD, no other files from SD card or whatever. The DVD player will only display a picture if a car the car is stationery, although the Audio will play all the time even when moving. There are ways around this, but using these affects the accuracy of the satnav, search on ebay for TVFree for example. What this does is block the signal from the wheel sensors to the headunit thus it thinks you are not moving, however the satnav uses these sensors when gps reception is poor (eg. along a tree lined road) to assist in calculating your position.
