Ulysse uses a GPS-based compass; as opposed to magnetic-based – it works only when moving.
Although this may seem like a disadvantage, it is totally uninfluenced by metal and electromagnetic fields; two potential problems that can interfere with magnetic-based compasses working correctly inside a car.
If a high-quality dedicated magnetic-based compass app is required, please take a look and download our FREE Gizmos* app from Google Play.


*Our Gizmos app also has integrated: Bubble level; Clinometer; Magnetometer; Map view; Location/waypoint address; Location/waypoint exchange;
