CoPilot is now offering US preloaded maps through the AppStore for $4.95. I took them up on it, and was able to also download Canada and Mexico (?) These make up the NA package offered at $19.95.
I have used it a number of times. It is loaded with features and settings - so for only 5 bucks - well worth it. I am sure this is a market penetration push by them, and I would not think it will last. They also offer other online services (like traffic), so they are hoping up-selling will make this profitable.
Downloading took a bit of fiddling around, but was not too much of a problem. At this price - would not even consider a torrent download even if it was available.
