Setting the GPS Position
Setting a GPS position is useful if you are not obtaining satellite information quickly because the
Magellan Maestro has travelled over 500 miles while turned off. Setting the GPS position will allow
the Magellan Maestro to compute which satellites are available and calculate the position more
quickly.
1. From page 2 of the Main Menu, tap User Options.
2. Tap GPS Options.
3. Tap Set GPS Position.
4. Follow the prompts to enter your current address.
5. Tap Done when you have finished entering the address.
Backing Up and Restoring Data
Backup and restore provides a way of storing the address book and other data to a SD/MMC card.
When the data has been backed up, it can be restored at any time. Please note that when you
restore from backed up data, address book and other data will be replaced with the data. The
Magellan Maestro cannot append backed up data to your existing data.
