Sygic McGuider is compatible with the inner screen of Nokia E90, and honestly, one of the best GPS applications I have tested so far. Its not full of gadgets like Garmin, Navigon or even TomTom, but Sygic is very good in the simple task of getting you where you want to go.
Intelligent address input, clean design, good menu navigation and high framerate even in the inner screen.
Screenshots and video as usual:
Clean design
High resolution
