So far I have unsuccesfully tried to make a hybrid 5.1/6/1 DVD for my 2007 Land Cruiser. I successfully copied the 6.1 DVD and it worked with no problems (including a fresh load after a battery disconnect).

The strange thing is that when I take my 5.1/6.1 hybrid disc to the vehicle and load it without a battery disconnect it is recognized and works fine with the 6.1 firmware. But, when I do a battery disconnect, it tells me to insert the proper navigation DVD (in English and Japanese apparently). Is my 07 Landcruiser navigation incompatible with the 5.1 firmware??? Any other ideas. Thanks to everyone.
