 Only buttons bar: Never will automatically change to next waypoint, only manually with
'NextWPT' and 'PreviousWPT' buttons at buttons bar.
Also from this options section, a default radius can be assigned for route waypoints, which will be
taken when this information is not available. It means, if we defined a radius for a concrete
waypoint of the route, it will be respected. But if it doesn't have radius the default one will be
used.
4.8.9 Altitude
„Main Menu > Settings > Navigation > Altitude‟
TwoNav features three altitude data obtained in different ways:
 Altitude: this is the data shown in the „altitude‟ field of the data bar, on the graph page
and to which the points recorded by the track along the itinerary are kept.
 GPS Altitude: Direct reading from the GPS.
 Barometric altitude: Reading from the barometric altimeter of the device.
Note: Although the data shown by default is the generic „Altitude‟, the data bar and the data
pages can be preset so besides the generic „altitude‟ they also show the GPS or the barometric
altitude (see Fields section).
The generic „Altitude‟ data can be preset so it observes different values depending on your
preferences. From „Menu > Settings > Off-road > Altitude‟ you will be able to select among the
following options:
 GPS: The values from the GPS will be directly taken.
 Barometric altimeter: The data from this utility will be taken disregards the GPS.
It is important to calibrate the barometer in order to achieve reliable data. You may
calibrate the barometer in 2 ways:
o Manual calibration tool: If you know the present altitude, you can enter it into the
TwoNav from „Menu > Settings > Off-road > Calibrate barometer‟.
