New X5 - Backup camera and other features not working

[B4BMW]

Hi Folks,
My new X5 (2008, X5 3.0si) is just six weeks old and yesterday my backup camera and iDrive menu were frozen multiple times and stopped working for couple of hours. Also, my memory settings (for seats and indicators) are also rolled back and stopped working for few hours. I have tried stopping/starting the engine thinking that the computer console will bring back all the systems clean but that didn't resolve the issue either. Few hours later, they started working by themselves. I called my sales rep about clarification and he asked me not to worry unless it happens frequently.

Do I have a defective camera and console? Has anyone noticed this problem (may be with relay switch or something) with their new X5s/other BMWs?

Thanks for your help.
