restoring from backups, lexus navi
Our 9.1 DVD got broken. Fortunately, I had backed up the data on a USB stick but I can't make another DVD that the car will read. I tried UDF 2.01, 1.5, and 1.02, and a couple different labels (can't remember which was correct for 9.1). Any ideas on how to make a DVD that works correctly? This is on a 2006 LS430. The master disc worked just fine until it got broken. I duplicated the old 5.1 disc and the duplicate worked just fine but then that was duplicating, not just from a backup.
Thanks.
Thanks.

1) The backup needs to be a perfect disc image, not a copy/paste from inside Windows. I recommend using Alcohol 52% Free Edition to make images.
2) Use a dual-layer DVD+R disc
3) Use a high-quality disc brand like Taiyo Yuden or Verbatim. Cheap blanks = poor laser reflectivity = poor reading by lasers not made to read burned discs.
4) You need to set the DVD Booktype to DVD-ROM. Use Alcohol 52% Free Edition if you need a free DVD burning program that supports this feature.
5) Burn using a Pioneer or Plextor burner. Some LG and NEC burners are known to burn backups that are unreadable by the Nav unit. If the disc doesn't work, try a different burner and/or brand of blanks.
Worst case, you'll need to acquire another backup..

thinkin, the original dvd drive broke down (shock shock) and it required considerable force to extract the original dvd from the broken drive. That is probably what broke it. Aside: I am working on replacing the mechanical drive completely and just use an SD card or USB drive so it will be MUCH cheaper than buying from Lexus. I have a few electrical signals to finish working out and we're there -- no more dvd drives that continually break down in Lexus or Toyota vehicles that cost from $55 to $100 thousand dollars! Grrrrrr. Plus, maybe we can eventually get rid of that <censored> lawyer screen.
Stan, I did everything you suggested except used ImgBurn instead of "Alcohol." Don't know what brand burner is in the laptop I used so will try an external burner connected to a Linux box that has worked for everything else I have used it for. And why do you say the DVD image must be a copy and not a built-up image from the separate files? Do you think the software looks for a particular binary image in a particular disc sector?
