Managing Your Tracks

The GPSMAP 378/478 draws an electronic breadcrumb trail or
track log on the Map Page as you travel. The track log contains
points along its path, including time, and location for each point.
The track log starts recording as soon as the GPSMAP 378/478 gets
a location fix. For the best results, clear the track log before you
start traveling because when the track log is full, new track points
overwrite the oldest track points.
The percentage of memory used by the current track log appears at
the top of the Active tab. After the track log is cleared, it shows zero
percent. When the track log reaches 100%, the most recent track
points start to overwrite the least recent track points (if Wrap is
selected for Record Mode). To avoid losing track points, save the
track log when it approaches the 99% mark.
Setting Up and Saving Your Tracks
You must first save the track log before you can use the Navigate
Track feature. The Save feature allows you to store up to 15 track
logs from certain times and dates.
To access the Track tab:
1. Press Menu twice to open the Main Menu.
2. Use the ROCKER to highlight the Track tab.

Active Track Tab
Record Mode—Wrap records over the oldest tracks when the track
log reaches 100%. Fill records a track log until the track log is full
(100%). When Off is selected, the unit does not record tracks.
Interval—Distance records track points after a specified distance
has been traveled. Time creates track points after a specified time
has elapsed. Resolution records track points based on the resolution.
The higher the resolution entered, the more points the unit creates to
make the track.
Value—records a track according to the Interval and Value. Enter a
specific distance, time, or resolution.
Color—select a color for the track when it appears on the map.
