The map shows the loaded route. Current waypoint is a green dot with a circle around it that denotes how close you need to be to autoselect the next waypoint as target.
The map is centered on the currently selected waypoint and the position will be shown relative to the waypoint. If the position is farther away than can be shown on the display the icon turns red and shows the approximate direction on the border of the map.
Secondary map mode is an overview map. Tap the overview to enter scrolling mode and move it around. Tap again to get back to normal function navigation.
### Info
After selecting a target and availability of a GPS fix the compass will show a checkered flag for your destination and a green dot for possibly available waypoints on the way.
As long as no GPS signal is available the compass shows the heading from the build in magnetometer. When a GPS fix becomes available, the compass display shows the GPS course. This can be differentiated by the display of bubble levels on top and sides of the compass.
If they are on display, the source is the magnetometer and you should keep the bangle level. There is currently no tilt compensation for the compass display.
You can select a waypoint from the "Waypoints" app as destination.
## Calibration
### Altitude
You can correct the barometric altitude display either by manually setting a known correct value or using the GPS fix elevation as reference. This will only affect the display of altitude values.
### Compass
If the compass fallback starts to show unreliable values, you can reset the calibration in the menu. It starts to show values again after turning 360°.
The widget keeps the sensors alive and records some very basic statistics when the app is not started. It shows as the app icon in the widget bar when the background task is active.
This uses a lot of power so ensure to stop the app if you are not actively using it.
