Rear view mirror for Hymer car

[69473]

Recently purchased Hymer Grand Canyon s with rear view camera(no interior mirror).
I'm a little concerned that when driving with bike rack and four bikes I can not see any part of it.
On my old van I could at least see part of it which was reassuring when travelling long distances.
The rear camera fitted works though the mbux screen and only when in reverse, does anyone know a possible solution?

Fit another camera, you may be able to plug it into the same display. I have a dual camera set up one angled down which shows when I select reverse, the other rearwards as a rear view mirror. I can just see the bikes in that. It also has a remote control so my passenger can select the reverse camera to get a better look at the bikes.

The camera only receives power when reverse is selected, therefore if you can find the power input and connect it to a perminent 12v supply wouldn't that solve the problem. Probably easier said than done
