It has to be said that good navigation solutions for UMPC’s are difficult to find. Despite an x86 platform being able to offer so much more than simple turn-by-turn guidance, no one appears to have put much effort into exploiting the possibilities. The package that appears to be coming out on top though is iGuidance and Frank (Ctitanic) has done a very good job of reviewing it against CoPilot and Autoroute 2007.
The one thing you can’t knock Autoroute for is price though. its the best value package there is by a long long way.
