Depends on your definition of "work." If you visit maps.google.com in the browser, it behaves likes it would on a PC. To pan the map, you make a stroke rightward from just outside the lower left corner, and click on the arrow icon that pops up. Then do the same things you would do on a desktop.

Now if you want it to locate you on the map with GPS, and give voice directions, and whatsit, then read the thread referenced in the previous post.
