Ok so I was on my golf forum of all places and in a discussion of the Prius there I supported another member's comment on the nav system being less than stellar. From that post I got a PM from another forum member who happens to be a Lexus master tech and I sent a few emails back and forth to him. Apparently the 05.1 DVD is the current DVD but Toyota is pressing their nav partner to release a new DVD ASAP due to a VERY large and growing number of complaints with the nav system running the 05.1 software. He said the current trend is to comp the customer's with the PREVIOUS version of the software which actually functions better than the current revision. From the info I got from this technician the DVD not only contains the maps but contrary to what I assumed it also has software that updates the logic tree of the nav system.

So I feel vindicated that it isn't just me and my friend with the Lexus RXH. This IS an ongoing issue for Toyota and they are supposedly working on a fix...I can't wait for the fix to be released.
