200 miles on the beast and the computer screen says "service park assist" or something close to that. Has this happened to anyone?
Second question is: What should my vehicle be doing when I am backing up? Obviously I can see what is behind me on the nav screen, but should there be beeps or something else going on?
Please help....

the yellow LEDs go on inside above the rear window ant it will beep when you get close to somthing. I've also heard that the passenger mirror is soppose to adjust down when you put it in reverse....but mine doesnt do that. I think there is an update the dealer can do.

I had a similer problem. Eventualy (about 900 miles on the odo) other electrical issues started turning up. It was traced to a computer communication problem with the alternator. I HOPE THIS IS NOT YOUR ISSUE, but if other similar problems arise, look there.

only the 2006's can be programmed with the mirrors to fold down and yes, the lights by the back tailgate that you can see in your rear-view mirror will come on if you are close to something and the truck will beep at you went you are really close to something.

It seems like the fold-down is not an option on the 2007 because the backup camera. No one has confirmed they can get the fold down on their 07's but many have tried and the dealers cannot find it in the programming menu.
