I purchased this stereo and installed it in my 2004 Ford Focus (Mk1).
I have powered the backup camera from the reverse light and haven't connected the purple/white wire of the stereo to anything.
The camera comes on as expected when I put the vehicle into reverse but when going forwards or in neutral, a black screen keeps randomly coming on with "Caution, the image may be reversed". This is obviously the backup camera screen but as I'm not in reverse, the camera has no power so it's a black screen.
How do I prevent the black screen from coming on when not in reverse?
I read this thread
and I believe one solution is to wire the purple/white wire from the stereo to the reverse signal. The problem I have is that this is not easily accessible and the fitting kit for the Focus which I used does not allow the stereo to be removed easily.
Is it possible at all to cure the black screen issue without wiring the purple/white wire to the reverse signal?
Any advice would be greatly appreciated.
