Hi Kirk,

There is a cover that opens to allow the camera a view of the road. the most likely diagnosis is that the cover has stuck shut (I have the problem that mine sometimes remains open as the headunit doesn't necessarily send the "shut" signal) or isn't receiving the "open" signal, but as the H/U says "camera" then that's unlikely really.

somehow you need to trigger the camera and give it a bit of a push I'd say...

Hope that helps,

Alan
