I've got a Toyota NAV DVD disc that I can't identify. The numbers on it don't quite match up with anything else I've seen reported on the internet, so I'm having a hard time trying to figure out what car/system/Nav gen it's for. Anyone want to take a guess? I've attached a picture of the disc itself. The numbers on it are as follows: 86271-53022 464210-0971 DATA ver.07.1 and the "secret code" in the upper right is "U22" with a "D" under it. At first glance from the long numbers it appears to be a 7.1 DVD for a Gen 5 system. But, the Gen 5 7.1 DVD that I have has a "U32" instead of a "U22" in the upper right. And, the actual contents of this disc are very different indeed. When I stick this disc into a computer, the disc label is 464210-0960 instead of the 464210-0971 listed on the disc itself. That appears to be a number associated with the Gen 4 7.1 DVD (as does the number "U22"). The actual directory listing of the mystery disc is as follows: Code: D:\>dir Volume in drive D is 464210-0960 Volume Serial Number is C7FC-60CA Directory of D:\ 07/02/2007 01:08 PM 52,234,240 LOADING.KWI 05/31/2007 04:47 AM 308,904 05.CMP 06/15/2007 03:20 AM 3,118,733,344 ALLDATA.KWI 02/12/2003 01:35 AM 299,536 DICVCE56.KWI 06/02/2003 12:23 AM 117 METADATA.KWI 06/02/2003 12:23 AM 34 SPEC.KWI 04/08/2007 01:21 AM 17 VERSION.TXT 04/17/2002 09:40 AM 218 COVERAGE.TXT 07/04/2007 02:12 PM <DIR> COVERAGE 05/24/2007 06:16 PM 4,228 INDEXDAT.KWI 07/04/2007 02:12 PM <DIR> IDX 05/18/2001 01:58 AM 458,752 VIRTUAL0.DAT 05/18/2001 01:58 AM 458,752 VIRTUAL1.DAT 11 File(s) 3,172,498,142 bytes 2 Dir(s) 0 bytes free Does that look familiar to anyone with a 7.1 disc for Gen 4 systems?

This nav system had NOT previously seen a 7.1 disc. The nav system did NOT update the firmware when using this disc. It did appear to work, however. It showed maps on the display, and gave me voice directions. Some things seemed slow to respond, though, and I only tested for 5 minutes, so I didn't test voice recognition. Later, when I inserted a known good Gen 5 7.1 disc, my Prius DID update to the 7.1 "I Agree-Free" firmware. Also, on the mystery disc, the .bmp files are readable in Windows. On all the known Gen 5 discs I have, the .bmp files are in some format that none of my graphics programs understand. On this mystery disc, I just double click them and they open right up. I've attached one here (converted to .jpg). Other than the yellow background (which I assume is identifying for transparency), does this look familiar to anyone with a Gen 4 system? At this point, I can think of only a couple of theories as to what this is: Theory 1: This is a perfectly normal Gen 4 7.1 disc that was mislabeled at the pressing plant somehow. This seems most likely, but then why does it work on my Gen 5 nav? For this theory to be true, the map formats would have to be the same across generations, and only have firmware or VR differences. I think that's the case, but I don't know for sure. Theory 2: This is some crazy bootleg or hybrid of releases and someone went to great effort to make it look like a legit release, but mislabeled it. Seems doubtful, because this is a stamped disc, not a burn, and even has little things like hub labels on the other side that say "North America u22 L1" and "North America u22 L0" So, any guesses? Who's up to the challenge of figuring out exactly what this thing is?
I think U22 is for the Gen4 hardware in the Highlander. It would be U32 for Gen5 hardware in the Prius. I actually need a U22 Gen 4 7.1 disk for my Highlander. Care to sell yours?
