Clearing All User Data
You can clear all user data, including all Favorites,
routes, custom POIs, tracks, mileage logs, and your
home location, at one time.
CAUTION: You cannot recover your user data
after it is deleted.
To clear all user data:
1. Select Tools > My Data > Clear All.
2. Select
Yes. The navigation system restarts.
Custom POIs (Points of Interest)
You can manually load custom points of interest (POI)
databases, available from various companies on the
Internet. Some custom POI databases contain alert
information for points such as safety cameras and school
zones. The navigation system can notify you when you
approach one of these points.
CAUTION: Garmin is not responsible for the
consequences of using a custom POI database or
the accuracy of the safety camera or other custom
POI database.
After downloading your POI database, use the Garmin
POI Loader to install the POIs onto an SD card. Then,
you can use the SD card to load the POIs into the
navigation system. The POI Loader is available at
www.garmin.com/products/poiloader. Refer to the POI
Loader Help file for more information; press F1 to open
the Help file.
When you insert the SD card into the navigation system,
a message appears on the screen, prompting you to save
the custom POIs to your navigation system. Select Yes.
If you select No, custom POIs do not work.
NOTE: Each time you load custom POIs to the
navigation system, any other custom POIs already
saved in the system are overwritten.
