This is 2013 right? NavFree Maps like these have been around for years.
There was already a thread on this where we discussed Forever Map and some other options.
Google Maps doesn't work worth crap offline although I've noticed that if I get a route and start navigation, it will happily hum along following me without a data connection. I don't think it could reroute if it needed to, though. I used this method for the drive from Whitehorse to Mayo with zero cell coverage anywhere but in Whitehorse and it worked for a full 5 hours with no data. But there's only one highway so it never needs to reroute.
TomTom (US & Canada) can be had on sale for like $30 when the time is right.
Because it could be considered a replacement for a map that people needed for centuries. I am not sure why people stick it to their windshields on the way to work though?Why do you all need GPS so badly? Horrible memory or really bad sense of direction. Nobody needed GPS until GPS came along. I think I used mine twice in 5 years for about 2 turns. They are a fun toy, but c'mon!
