I successfully used the loading.kwi file from the 5.1 Navi DVD to load and use the data from the 9.1 Navi update for a Gen 5 system today. I found that the easiest way to make sure that the system completely reloaded was to pull the battery positive lead. The Radio 1 fuse disabled the screen, but the Navi was not powered down. The Radio 2 fuse didn't do it either. It was simple to simply pull the positive battery lead -- and then reset the clock in the car and reset the seat memory. When the system reloads properly, you get a message saying that the DVD is being reviewed. I didn't have any problems utilizing a Verbatium DVD +R DL.

I created a 7.1 hybrid using the 5.1 loading file with no issues on a Generation 5 Lexus Navi. The media was a Verbatium DVD +R DL that I purchased at Best Buy. I burned it on a HP computer of recent vintage using the "click to DVD" software supplied as OEM software. I created a double layer "closed" data DVD. I burned the DVD at the speed specified by the media (5X). I can override the motion lockout as described in multiple posts elsewhere. I don't know yet whether the same technique works on a 9.1 update. I'm going to try.

I've NEVER reliably heard ANY loading file being successfully mearged with any data base past 6, but you can always keep trying. The world needs more coasters. :P

Has anyone successfully created a hybrid DVD from the 9.1 update that retains the over-ride for motion lockout from the 5.1 update? I read elsewhere that users with Generation 5 Navi systems were successfully using 7.1 data with the old 5.1 software that includes the over-ride feature.
