the message “Tracking is disabled.” Click the Start Tracking button.
One of the following messages may appear in the Tracking Status field:
“Trying GARMIN format”, “Trying NMEA format”, “3D Navigation”,
“3D Differential”, “2D Navigation”, “2D Differential” or “Poor GPS
Coverage.” As MapSource reads the GPS data, the tracking data will
appear in the GPS Tab data fields below the Tracking Status field.

GPS Tab Data Fields
Real Time Tracking on the GPS Tab
The GPS Tab displays the data gathered from the GPS in real time,
including tracking status, speed, altitude (not available in NMEA format),
current compass heading (‘track’ field), compass bearing, position coordinates, date and time.
EPE— (Estimated Position Error) The number in this field indicates
the estimated accuracy of of the horizontal position fix.
DOP— (Dilution of Precision) This measures satellite geometry quality (the number of satellites received and their location in relation to
each other) on a scale from one to ten—the lower the number, the
better the accuracy (not available in GARMIN format).
Keep Vehicle Visible on Map— With this function selected, the
vehicle (red triangle) will remain centered on the Graphic Map during
real time tracking, and the map display will continually change to
show where the “vehicle” is traveling. Check/uncheck the box to
select/deselect this feature.
Record Track— Check this box to select or deselect this function
to have MapSource record the track that your GPS is navigating.
MapSource will automatically assign a track name and display it in
the Tracks Tab List.
