It's pretty easy to confuse right and left with the computer-generated voice. I've noticed that on my Palm with Mapopolis as well as MM. The voice makes them sound very similar, for some reason. Just look at the display, and it also helps to know which way you're going to turn by checking the route in advance. That isn't always possible, I know.

What I'm waiting for on this app is the ability to dynamically reroute after a wrong turn or detour, or just knowing that there is a better route. With that, it would be perfect. Until I get that, I'll keep my old Palm running Mapopolis available. It will take two GPS receivers, but luckily I happen to have two available.
