Newb to the site, but not a newb to forums - searched quite a bit and have not seen this particular issue. I've had complete success in the past with Lexus navigation discs, the Lexus Generation 5 hw/sw (also sold as Eclipse aftermarket) had a firmware version with an override feature I like to retain, so I've put together hybrid discs with early firmware and later maps a few times. I got a 10.1 disc, and used ImgBurn to create an ISO and MDS. In the past, all I've needed to do to validate the ISO works is burn a new disc by selecting the MDS and putting a new Verbatim DVD+R DL in my Samsung (TSSTcorp CD/DVDW SH-S182M SB06) burner. I persistently get a layer break error preventing me from writing anything to the disc.

Optimal layer break position must be a multiple of 16
Optimal L0 sectors 2,026,393
Next largest acceptable value 2,026,400

Log looks like this:

I managed to burn one by manually setting the L0 break at 2,026,400 and I tested it briefly in the navigation unit. It appears to work. Is manually changing the layer break for what amounts to an exact copy expected? Am I doing something inherently wrong causing this problem, or is it possible Lexus is trying to make copying/archiving this data more difficult?

I did try to change the write speed, but nothing seemed to make any difference until I manually set the layer break.

Put the original disc in your drive, go into Read mode and copy + paste the disc info from the box on the right please.

It's not normal or expected, no.

That disc just seems to have a layer break position that cannot be duplicated exactly onto DVD+R DL media.

If the one you've burnt seems to work ok, I wouldn't worry.

It seems to work correctly, but without testing all 10 map zones, it's hard to say if it works correctly or not. I can surely say it works in the region where I live, but that's all I can say with any certainty. It does find Starbucks a lot better than the previous version!

lol well that's all that matters then!

People that live and die by Starbucks seems to have a 6th sense for finding them anyway ;)

Plus there are so many of them that you're never far enough away to actually need satellite navigation!
