Wow, over $1000 (around $1025 possibly a universal DVD NAV one) for the DVD NAV disk (oh well, I am glad I do not have to pay for it, because I would not even bother) .... ok, today I went to toyota dealership as I was asked to have a technician diagnose if I had the issue so I could get the new DVD NAV map under TSB EL012-06 for my 2006 Sienna and indeed I will get one in a week possibly after ThanksGiving and hope it will be ver. 06.1 or later...
