Did a search and didn't find too much discussion on navigation on our ipads. I see that at least copilot has a HD version, but doesn't look like TomTom does yet. In any event what does everyone thing about which navi program is the best right now? I was going to pick up TomTom but they haven't released a HD version yet and I really need a gps now. Please list what you use, how you like it, if it's made for the ipad or not, and what you like/dislike about it.
