I downloaded a upgrade nav dvd but it was not the right one it loaded and then went haywire everything was Japenese and it said insert the correct disk. Well after trying everything I found on the internet from battery removal from drive to removing all wiring to the drive system take out its battery Ect. Ect. nothing worked I went to the dealer 2/9/08 today to have them fix it for 45.00 I am also out of warranty too so I thought that was a fair price since I screwed up my wifes car The couch was getting really uncomfortable boy was I in the dog house I think I watched to many Home Improvment shows. They told me to bring the original disk so they could reset the system and restart with it . But it would not work they said that you cannot go backwards for instance if you tried to upgrade with version 3.2 from your system disk of 2.1 that it will not reboot backwards so whatever version you upgraded too you has to be at least one step higher as far as versions go for it to fix itself it It so happens one of the techs there just upgraded his system and had a extra disk that was a newer version than mine they tried it and walla it booted just fine they just charged me 45.00 to my disbelief.. lexsus of tulsa a great company So you can do 1 of three things 1. Go buy the latest version 2. Find a friend with the same generation and a newer version than you had. 3. Drive around looking at the japanese You do not have to upgrade you nvram or anything else just follow this an it will work. If I have helped you let me know revrnbob@cox.net
