There are a few instances in which you may want to perform a master reset on your GPSMAP 62 or 64 series device, including the following:
1. Not receiving a satellite signal
2. Restoring the factory default settings
3. Device not functioning properly
Performing a master reset can cause data loss. For assistance backing up user data*, see the FAQ “How do I back up user data from my outdoor GPS with a USB interface?".
Note: If removing user data is desired to eliminate corrupt data or free up additional space, reference the FAQ “Why does my Garmin outdoor or fitness GPS still show my GPS data after a master reset?”.
To perform a master reset:
Ensure the device is powered off
Press and hold Page and Enter simultaneously
Power on the GPS while continuing to press both buttons
Release the buttons once the Do you really want to erase all user data? message appears
Select Yes (You may have to press Enter on the Yes option more than once for your unit to re-boot)
The Device will reboot and then prompt you to select Language required
