MobileNavigator North America
MobileNavigator has a set of strong features, including an excellent computer-generated text-to-speech voice, the ability to keep a strong fix on the GPS and refresh streets in a noticeably better way than most competitors, and smooth animation in 3D.
The software pops up several unobtrusive but useful navigation aids, including lane diagrams on multi-lane roads, highway signs to make exit choices clearer, and next-next-turn indicators, showing the direction and nature of the turn following the current turn.
The program also allows an in-app upgrade to include traffic data for a one-time $20 fee. This increases the utility of the program, especially for regular commuters who need to know about traffic conditions and don't need navigation assistance except for clever re-routing without requiring a recurring fee.
But the program suffers from two defects, neither of them showstoppers, but both significant. It recognizes few addresses from the Contacts list, including ones that even other middling performers find just fine. And the 3D display is coarse and sometimes difficult to read or figure out, with POIs overlaid like mad. Other programs remove POIs while a user is driving, or has an option to disable some or all POI categories.
Improving both defects would put MobileNavigator at the top of the pack.
