VW camera little problem

Hi

I mounted an adapter from VW camera to CVBS and it works perfectly (it's connected to ACC, so works at all times - at the same time it has a delay built-in.

The little problem is, that after the delay it disables properly but for a second it shows an warning "Rear Camera function not available" or something like that.

Should I just live with it, or can I fix it somehow?
