I received and installed my free Nav disc update from Chevy. today (Map data version 4.1c) for my '07 LTZ factory NAV For the first time this particular disc contained a firmware (software) update as well. No big deal here, it only took about five minutes to load and then rebooted the whole unit when done.
I first noticed that the font on the digital clock was larger, that's a plus. When I shifted to reverse to back out of my garage it lit up my reverse camera way faster then before, meaning not any lag time, that's a plus definitely. HOWEVER when I went to play with
the navigation itself ALL MY FRIGGIN address book entries were FRIGGIN GONE. The entire address book was empty. even "previous destinations" were erased.
I made it through the last two DVD updates without this happening so a full two years of destinations are completely GONE.. I am reasonably certain that there is no way to recover these as they were stored in the firmware ROM chip that just got flashed. If I am wrong please post accordingly. My beef is that there should have been a warning about this on the DVD sleeve and I could have copied down the important destinations onto PAPER if I had to. Thanks for reading my Whine MacTahoe

You cannot get that data back. And you're right, there should be a warning letting you know that your data will be erased, as well as giving you a "cancel" option so you can copy that data down. As with any firmware upgrade it is always smart to do that on your own anyway. I personally won't upgrade any electronics without doing a back up, or in this case writing it all down before starting.
