Track Log File Tab
The StreetPilot III automatically records a history of your locations in the ‘Track Log’, creating an
electronic ‘bread crumb’ trail of the path you have traveled. Once full, new track points will replace the
oldest track points. The beginning of the track is the earliest point while the end is the most recent.
Recording - Select On or Off; On to record tracks, Off stops tracks from being recorded.
Percentage Full - Shows the percentage of track memory used.
Clear Track - Clears the track log from memory.
Interface Tab
The ‘Interface’ fi le tab provides the following input/output settings:
• GARMIN— the proprietary format used to exchange waypoint, route, track log data with a PC.
The format used for database updates and to save optional MapSource CD-ROM data
to an installed data cartridge (also optional).
• GARMIN DGPS— the proprietary format used to receive differential corrections from a GARMIN
DGPS Beacon Receiver and automatically scan/tune beacon frequencies.
• NMEA OUT—supports the input/output of standard NMEA 0183 version 2.30 data.
• Text Out— supports a standardized, fi xed-column ASCII output with data for position, track,
speed, etc.
• RTCM In— allows Differential GPS (DGPS) input using a standard RTCM SC-104 format, without
any output capabilities.
• RTCM In/NMEA Out— allows DGPS input using a standard RTCM format and also provides
NMEA 0183 version 2.30 output.
Press the ‘Clear Track’ Button on the Track Log Page to
clear all of the stored tracks.
The Interface Tab provides for eight possible Input and
Output settings (including ‘None’).
