Garmin is the leading GPS navigation, communication and solar
devices developer in the world. Among its popular products are Garmin
N?vi, Garmin StreetPilot and Garmin Zumo (for motorcyle) series of
automobile in-vehicle GPS receiver and navigation unit. Garmin GPS unit
allows user to update its firmware, add custom POIs (Point of
Interests), Waypoints, Favorites and customize other user settings.
Most GPS navigation devices from Garmin has a reset function which
allows user to access a Maintenance Mode screen with system
information, diagnostic details or perform the reset function to
restore Garmin Nuvi or other series unit to its original default
Depending on which model of Garmin GPS unit you're using, the
following routine can reset the Garmin device to original factory
loaded settings, or bring up the Maintenance Mode with access to System
Information and View Diagnostics screen, where users can see various
logs, and of course, clear all user data (reset to factory defaults) or
In order to reset Garmin device or enter into maintenance mode, perform one of the following procedures:
Power off Garmin unit. Press on continuously the upper
top left corner of screen and then power on the unit by pressing once
on the Power button. You should be prompted to clear all user data, or
asked if do you really want to start up in maintenance mode. Press
"Yes" to reset (warning: all data will be erased and lost, so backup
before proceeding) or enter maintenance mode.
Hack above works on Garmin Nuvi 660, 680 series.
Turn off Garmin device. Press down on bottom right
corner of the touchscreen, and then power on the GPS unit. You should
be prompted whether do you really want to erase all user data, or asked
if do you really want to start up in maintenance mode. Press "Yes" to
reset (warning: all data will be erased and lost, so backup before
proceeding) or enter maintenance mode.
Note: If entering maintenance mode, it's also possible to perform master reset by selecting clear user data option.
Once the device has been hard reset, user have to perform the set up
procedure again upon start up. Note that erase user data command only
delete data in the Garmin unit's memory that isn't accessible to the
user when the unit is connected to computer. The command does not erase
.gpi or .gpx files loaded (if your .gpx files contain any waypoints
then they will automatically be imported into Favorites), nor will
delete any MP3 music, JPG photos or any other files that have been
stored on the GPS memory card.
Once the Garmin GPS unit is reseted, remember to place the device
outside where there is a clear unobstructed view of the sky for 15 - 30
minutes in order for it to requires fix to GPS satellites.
Unfortunately, even if you perform master reset on Garmin GPS unit,
it does not reset Garmin Lock security feature, which password-protect
most Garmin electronic devices to deter theft. If you forget the PIN or
password unlock code to unlock the Garmin unit, the best solution is to
bring it to Garmin to get unlocked. "Secure Location" does not unlock a
locked Garmin unit either as it's only a temporary fix as when it's
turn on outside the security location, the device is locked again.
