Managing Your Tracks
The GPSMAP 580/585 draws an electronic breadcrumb trail or track
log on the Map Page as you travel. The track log contains points
along its path, and includes both time and location for each point.
The track log starts recording as soon as the GPSMAP 580/585
obtains a location x. For best results, clear the track log before you
start traveling as 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 overwrite the oldest 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 save the track log before you can use the Navigate Track
feature. The Save feature allows you to store up to 50 track logs.
To access the Track tab:
1. Press Menu twice to open the Main menu.
2. Highlight the Track tab.
