Yesterday I successfully updated my nav software from v24 to v27.1, (2005 X5 3.0) and using the 2006.2 maps. I enabled the perspective mode, AND created a new splash screen as well.
It took a while, probably wasted about 8 discs, as I was burning the update CD incorrectly.
Now it works just fine. I noticed I don't get the initial message screen with the Accept button any more. It jumps directly from the splash screen to the maps.
