Looking very good. Yea, you'll be pleased with iGuidance. Used to use mapopolis on a pocketpc, and Delorme Street Atlas on a laptop. It doesn't have all the in depth options and configuration options those had but I find I don't miss them and it works very well with a touchscreen in a car environment.
What software are you using for DVD playback? The "builtin" media player classic? If so does it resume DVD's if you stop it or after switching to another screen?
