Try bing too.
I like the older WM6 version. It will track you utilizing your internal gps also and you can search for locations by speaking the name of your destination.
It has audible notifications to remind you to turn. The WinMo version of GoogleMaps doesn't support spoken directions. I kinda like bing a little better because it at least has the alert tones.
