I purchase this unit since they aren't supporting my old XXL 550M, although was still able to update my Life Time maps. Anyway\nmy new GO 520 3 days ago and I was able to register and set it up. But now with 4 updates waiting I can't do anything with it. It won't even connect to any of my computers. Also what's up with Tom Tom all I get is errors when I try to go to any of their sites. I can't even sign into to my account.
