Works fine on the software from Falk or manually to a memory card (if the slow USB 1.0 Falk dislike)
Private:
Basically, the data material is not objectionable. There are known a large number of roads - very small, you would not really call the road with us. Unfortunately, the navigation in the US national parks is not working very well. In particular, in the Grand Canyon NP and Yosemite NP the map material was obviously outdated and sometimes even inaccurate (there was very good Satelitenabdeckung). Were in both parks and wanted the Navi drive long detours because roads unknown or official Park exits were not known. So far so good.
As best just adequate, the data material with respect is to refer to existing speed limits: despite generellem limit none at all is often displayed. It has also been generally almost always incorrectly displayed image (instead of 35 mph was 40 or 30 appear).
Conclusion:
Basically very useful card, priced lower than a Navi spot at the car rental companies to rent. Speed limits are not installed properly or was not entered. National Parks could be covered better and more correct. Because of the shortcomings only 4/5 stars.
