Pros: Mac OS X native support

Cons:
1) Streets that should exist and have existed for many years do not appear in your application (out of date maps)
2) Addresses on this streets are not in the map database while other addresses appear with no streets if you run the curser over the area
3) printing of driving directions only print a picture of the route not step by step directions
4) sometimes while driving, the GPS location marker disappears from the map
5) the refresh rate of the GPS marker on the map is slow to update.
6) no speech support
7) the step by step directions that appear in the application do not progress based on GPS position.

One last note, you can not return the product to the company for any reason. I tried because of the 7 issues above any was sent the following email.
