Routing Settings
The available routing settings vary based on the activity selected.
From the app drawer, select Setup > Routing.
Activity: Sets an activity used for transportation while routing. The device calculates routes optimized for the
type of activity you are doing.
Calculation Method: Sets the method used to calculate your route.
Lock On Road: Locks the blue triangle, which represents your position on the map, onto the nearest road. This is
most useful when driving or navigating on roads.
Off Route Recalculation: Sets recalculation preferences when navigating away from an active route.
Avoidance Setup: Sets the types of roads, terrain, and transportation methods to avoid while navigating.
Route Transitions: Sets how the device routes from one point on the route to the next. This setting is available
only for some activities. The Distance option routes you to the next point on the route when you are within a
specified distance of your current point.
Heading Settings
You can customize the compass settings.
From the app drawer, select Setup > Heading.
Display: Sets the type of directional heading shown on the compass.
North Reference: Sets the north reference used on the compass.
Go To Line (Pointer): Allows you to use the bearing pointer that points in the direction of your destination, or use
the course pointer that shows your relationship to the course line leading to the destination.
Compass: Automatically switches from an electronic compass to a GPS compass when you are traveling at a
higher rate of speed for a period of time.
Calibrate Compass: Allows you to calibrate the compass if you experience irregular compass behavior, for
example, after moving long distances or after extreme temperature changes
page 22).
Altimeter Settings
From the app drawer, select Setup > Altimeter.
Auto Calibration: Automatically calibrates the altimeter each time an activity is started. The device continues
to automatically calibrate the altimeter as long as the device receives GPS signals and auto calibrate
continuous is on.
Barometer Mode: Variable Elevation allows the barometer to measure changes in elevation while you are
moving. Fixed Elevation assumes the device is stationary at a fixed elevation, so the barometric pressure
should only change due to weather.
Pressure Trending: Sets how the device records pressure data. Save Always can be useful when you are
watching for pressure fronts.
Plot Type: Allows you to view elevation changes over a period of time or distance, barometric pressure over a
period of time, or ambient pressure changes over a period of time.
Calibrate Altimeter: Allows you to calibrate the barometric altimeter when you know the correct elevation or the
correct barometric pressure
Position Format Settings
NOTE: You should not change the position format or the map datum coordinate system unless you are using a
map or chart that specifies a different position format.
From the app drawer, select Setup > Position Format.
Position Format: Sets the position format in which a location reading appears.
Map Datum: Sets the coordinate system on which the map is structured.
Map Spheroid: Shows the coordinate system the device is using. The default coordinate system is WGS 84.
