Well, I guess I can't actually say about the map update, but there are periodic updates to the app, as a matter of fact, as soon as I got done downloading the huge app, it prompted me to down load another large maintenance update. As far as I can tell, the map and graphics work just like google or apple maps, no hang ups at all that I saw. I do have a cellular Ipad also, so I have the gps capability built in.
The description in the Itunes download area states lifetime maps......I only saw people complaining about updating their stand alone unit. Most did not know they had to hook it up to their computer to update the software. Well, between Google maps, Apple maps, my Garmin, and this app....I think I could navigate to the end of the earth and back
I LOVE gadgets!
