11.1. Navigation (follow a route)

ViewRanger will help you navigate to a point or follow a route. You need to be connected to a GPS receiver and then choose the point or route you wish to use.

Navigation arrow

Navigation arrow

To follow a route or navigate towards a specific mark, point of interest or waypoint:
Select the route, POI, Mark or Waypoint that you wish to use. You can do this through the Organizer or by touching the object on screen.
Once the point of interest or waypoint is selected, choose Navigate to or Follow route.
When you follow a route, ViewRanger automatically works out which waypoint you should head to next.
ViewRanger shows a navigation arrow at the top of the map view. The arrow indicates the direction to go to reach the next point relative to your current heading. You should aim to keep the navigation arrow pointing straight up. If it points left then turn left, and so on.

There are two alarms which are individually switched. The POI/waypoint alarm sounds when you arrive at a target point. The XTE alarm (cross track error) alarm sounds when you go off route. Switch these alarms on and off using the Menu tab > Settings > Navigation menu. Change the alarm tone in the same menu as well as to set the distance at which the arrival and XTE alarms sound.
To silence the alarm press Menu button and choose Navigation or press the Navigation Arrow. Select 'Silence alarm' - this will silence the alarm so it does not sound again. To switch the alarm on or off choose Menu tab, Settings, then go to GPS & Navigation and use the POI/WPT/XTE alarm switches.
If there is a link to a sound or video in a waypoint's description this will be played when you first arrive at the point.
To stop navigation of follow route press the nav arrow.


Navigation settings

There are three settings that control navigation. All are set in the GPS tab of settings.

  1. Arrival alarm distance - the distance at which the arrival alarm sounds and the navigation arrow turns red. This is the grey outer circle in the picture.
  2. Cross track error (XTE) alarm distance - if you go more than this distance away from the route the cross track error alarm sounds and the navigation arrow turns blue. This is shown as the dotted line.
  3. Show next waypoint distance - when you reach this distance away from the waypoint you are considered to have arrived at the waypoint. The navigation arrow will now point at the next waypoint on the route, so you know where to go next. This is shown as the red inner circle. The arrival alarm will still sound, so you know you are at the waypoint.

Route Details

Extra route details are held in the route details page.

Manual Route Navigation

Navigation menu

The navigation menu is accessed by pressing the nav arrow.
You can also manually select waypoints to navigate towards, rather than using the automatic method described above.
To navigate to a specific waypoint first select the waypoint, then from the context menu choose Navigate to. You can also select a waypoint you can use the route's waypoints list.
Once you have chosen to navigate to a particular waypoint you can step forward or backward by using the Navigate menu's Step target forward or Step target backward commands.
You can start using the automatic route following using the Navigate menu's Auto follow route on command.

Going Off Route

If you go off route by more than the cross track distance, ViewRanger will re-evaluate where you are. If it finds that you are closer to a later leg of the route it will direct you along that leg. It gives preference to the earlier route legs. However, if you return to your route it will revert to directing you to the next waypoint.


The most important setting is the Show next wpt distance. This defaults to 15 metres. If you find that the navigation arrow points to the subsequent waypoint too soon then reduce this setting. The arrival alarm distance only determines when the arrival alarm triggers. Normally you want the alarm to trigger as you approach a waypoint, so keep this settings greater than the next waypoint distance.
