Reverse camera not working?

After battery change, when I select reverse gear the display changes to the rear camera but without the green/red guide lines which should appear. Instead 'System not ready' is written across the screen. Is this a known fault that anyone is aware of? Already I have disconnected and connected again the battery, with no result.

Hello there,

I have the same problem. I just replaced the 7.5 amp CRT fuse and the problem is still there.

I used the fuse which was in the fuse box (as replacement).

My question: is the solution 100% the crt fuse? Did I had bad luck and had also a bad fuse in the replacement box? Or could it be another fuse to replace?

Thank you
