Not necessarily to hijack the thread but:

Mine has developed an intermittent video (mostly blank) when going into reverse. When it does kick in, sometimes it's fine, sometimes there is static or sometimes it's off color. Where would be a good place to troubleshoot this sort of issue?

Hasn't been too much of an issue when my X5 was running (see rear diff threads) and was planning on doing an android tablet swap on the CCC anyways with camera but just curious.
