nuvi hard reset procedure

Hard Reset warnings:

* Note that this procedure has been known to delete your favorites so back them up beforehand: From the nuvi drive, copy x:/Garmin/GPX/current.gpx to your backup location. After the hard reset, copy current.gpx back to the same folder on the nuvi but rename it temp.gpx (important). On the next power cycle, the favorites will be read from temp.gpx into the non-user accessible memory area on the nuvi where they are actually stored (current.gpx is only a shadowed backup of your favorites)

* Note that this procedure will clear all user selected settings under Tools>Settings like map view mode, navigational settings, selected vehicle, selected voice, etc. These settings will need to be re-configured afterwards. It will also clear out your Recent Finds so make sure you save these as favorites or archive them in another way. Maps, vehicles, voices and user-loaded custom POI's stored on the unit will not be disturbed.

Hard Reset Procedure: (All except the 8x0/8x5/37xx series units):
1. Power the unit off.
2. Press and hold (and continue to hold) the bottom-right corner of the screen while powering the unit on.
3. Continue to hold the screen until the "Do you want to erase all user data?" prompt appears.
4. Press "yes" and the unit will reboot.

Reset all your location settings and user preferences. Also restore your favorites using the method outlined at the beginning of this post.

nuvi 8x0/8x5 series hard reset:
To perform a master reset on a nuvi 800 or 805 series device:

1. Remove battery from nüvi
2. Place battery back into nüvi
3. Touch-and-hold the bottom right corner of the touch screen when a progress bar appears
4. Release the screen when "Do you really want to erase all user data?" appears
5. Touch "Yes"

Reset all your location settings and user preferences. Also restore your favorites using the method outlined at the beginning of this post.

*Note that a "power-cycle" (or power-on/power off sequence) on the nuvi 8x0/8x5 units consists of removing, then reinserting the battery into the unit -or- sliding the power switch to the ON position and holding it there for ~10 seconds. Using the power switch normally on the unit (slide to ON position and immediately release) to power it off only puts the unit into a "sleep" mode.

nuvi 37xx series hard reset:

1. Power off the unit (press/hold the power button for ~7 seconds)
2. Power on the unit
3. When the Garmin copyright screen is displayed, press & hold the bottom-right corner of the screen
4. Release the screen when "Do you really want to erase all user data?" appears
5. Touch "Yes"

Alternate method:
1. With the unit powered on at the map screen, press the bottom-right "Speed" field which will take you to the Trip Computer page
2. Press/hold the area just above the numerical speed on the round speedometer dial (where the compass heading is displayed when moving)
3. After pressing this spot for ~7 seconds, you will enter diagnostics mode
4. Select the first option displayed "Clear all user data", then follow the prompts

Reset all your location settings and user preferences. Also restore your favorites using the method outlined at the beginning of this post.

If possible after the hard reset (all units), let the unit sit outdoors in the open for about 30 minutes or so to let the unit re-acquire satellite almanac data.
