Ah, thanks Ben, but that's some really old news. Most of us have gotten the update or are waiting until closer to December hoping for an even newer update.
We have the DVD, ver. 3.2 if anyone's interested in not waiting for the new update but wants to wait on their free update for a future version. Willing to send at cost if anyone's interested.
Just to let the interested know, there are errors on the 4.2 version BUT they are not critical at all. Since I ordered what I wanted in a car for the first time in my life, I wanted one with all options. I really did not expect to use the NAV as much as I have, but the usage has been several times higher than I thought, and very useful to me. An all options Prius is a bargain in the midsize car area.
Simply call your dealer, mention LSC-40J, and give them your VIN. It's free if your Prius is involved.
oh, didn't know 3.2 was that old. but since i had it i thought i'd offer. i don't have nav so i don't know what's new all the time.
