Android dvd player

[macgy]

I just installed android dvd player in my e39 and a rear parking camera that comes with it.
When I put the car in reverse, there is grid lines on the monitor, however the grid lines doesn't move when I move the steering, is there a way to make the grid lines moves as steering turn?
Anyone did this before?

Sorry to accidently left my tread in yours..back to your question. .leaving the car 3 weeks without start will not be a problem if your battery is still good..but if u r still worry..just take out the negative terminal.
