my velo 2401g was going on and off but has now stopped completely on the screen it says in the top left corner 'backsight' and in the middle of the screen it says no signal what could be wrong
sounds like the rear view camera is faulty, check it has power and is well connected to the back of the DVD unit.
If you dont have teh camera installed check no wires have touched the car framework and "earthed out"
