I purchased the N. America maps this afternoon. I don't recall what that last, wide button read ("Finish," perhaps?), but, after I pressed it, I got a blank white screen and nothing else. I finally had to reboot my tablet. Even killing the task in the applications manager would not get me more than a blank white screen.

Thanks, Jim
Btw: I know why you're doing it, but I had to chuckle at "N. America + Mexico." Mexico is part of N. America :)
close Navigator and delete data in Android settings/application manager/Navigator - then reboot your phone. If this does not help, please email logs (navigator/log folder).
"N. America + Mexico." Mexico is part of N. America not according to TomTom :-)
