Ihad my n2 installed a year ago. The installer said he bypassed the driving restrictions for me. Cool. Everthing was available to me while driving. Movies, rear video input, POI, maps, you name it.
I downloaded the v60 disk, burned it a DUAL layer, and upgraded my system. I can still watch movies while driving (at least from the external inputs, have not tried the internal DVD player though), but what I can't do it enable / search the POI or any of that stuff. Bookmarks work fine, but parked or driving. Ebrake switch or not, I can't get into about half of the features of the GPS portion.
