Agree on the overanalyzing. I bought 15.1 so I'd have current Nav info if no phone for some reason. Also my usual OCD on having a perfectly maintained LS. I'll give you 0.85 for the '05 disc. Hopefully 30 day return and must have certificate of authenticity

I really don't understand why copied discs would cause an issue with the nav system...that is not how computers work. What I mean is, the discs are read-only and, even if some of the later disc versions update the nav firmware, there are usually checksums performed to validate a firmware update before the system fully commits it to the EEPROM, otherwise the system maintains a backup of the original firmware to restore from. At least that is how most computer firmware is designed and I would expect Lexus to follow best-practices.
I purchased a disc off eBay for our 06 LS and proceeded to make a copy for the wife's 06 ES because they're both on the same Gen(4?) system. My wife's nav has worked fine for over five years and with three different copies of nav updates before we did the copy with the LS disc, and I wouldn't expect it not to work. However, I do use quality dual-layer DVDs (Verbatim rather than bargain bin Memorex) and burn at a relatively slow 4x speed. When making image backups, it is a bit-for-bit identical copy of the original and does not exhibit the quality degradation you'd see from an analog copy, such as old VHS tapes. The only way I can see the copy being corrupted is if it is on cheap discs, the person burned it too fast without buffer-underrun protection (which even native Windows 7 and all authoring tools have had for a decade), or they burned it using a wrong format (such as data vs DVD format; data is fine in this case), or they dragged-and-dropped data from the original disc to their harddrive and them moved that onto the blank disc (you can miss hidden files by using this drag-and-drop method). Now that I've typed it all out, I guess there are several ways for screwing it up but it just seems so simple, without any special advanced software/hardware, to burn a disc image copy. ImgBurn is a great free tool for making image (bit-for-bit) backups.
I see absolutely no benefit from buying the OEM disc at OEM prices. Even if you had to buy a dozen discs from eBay, it would still be cheaper than the OEM disc. Canon and Epson have also had consumer printers for years that could print directly on disc surfaces, so there isn't really anything to it to make a close facsimile of an OEM disc art. You'd just need to pay for the low-cost printer and inks, which inflates the price of the copied disc (but you're just paying extra for decoration that you'll never look at once the disc goes into the DVD drive of the car, and the disc art doesn't impact functionality). As long as the seller made an image backup (.iso file extension) onto a quality disc, I can't imagine there would be issues, regardless of what is printed on the top of the disc. Sorry if this is a little of a rant. There isn't really anything to it for making functional copies of the OEM nav disc.

02lex430, did this error just appear or did you see it also during your test drive before purchasing the car? I believe others are correct about the Gen 3 UO8 13.1 as the latest version for a 2002 LS.

Along this topic, I'm no expert....for some reason, a commercially produced CD skipped in my LS...I thought oh boy.....every other CD played fine in each of the 6 positions. Exchanged it, and the 2nd CD did exactly the same. Had no choice but to obtain refund. Made the mistake of downloading one of the tunes, and BAMM! Got charged for the entire CD....the copy I made myself was even worse, skipped worse. Prolly an expert could explain what's going on, this is simply audio. I don't like mp3s in theory as they are compressed and from what I understand lossy, why would anyone buy them....which is why I"m willing to pay for commercial cds (coworkers all say what planet are you on, music is free)...
Mastered CDs use a metal die of the exact pit formation and it is physically pressed into the CD (too fine for us to see with the naked eye). When we make copies at home, instead of pressing the data into the plastic our burner uses a high-powered laser to etch the pit pattern for the data bits (0 or 1 being represented by hills and valleys). As the laser burns the data in you'll later notice a color change in the media when you take the disc out of your home burner. Here is a link about the process:

Did you by chance try the troublesome CD on a home CD player to compare against the LS CD changer? Did the commercial disc have the typical silver reflective layer or was it a different color?
