City Navigator was tested with a Garmin eTrex. - Very useful and practical city - Good mileage estimate - Changing the automatic zoom at intersections to indicate the approach direction, against the zoomed display screen for a long time on the cross even after passing the junction, the risk of not being able to anticipate the following intersections. - Estimation of amazing itineraries. Many subtleties settings (auto, bicycle, pedestrian, toll, fastest, shortest ....) results and sometimes bizarre or too long. - Difficult, compared to a real card, establish yourself as a route by zooming out, the small roads disappear from the screen and only remain the main roads.
