SOURCE: Reboot the Nuvi 360 to "Mass Storage Mode"

Try these two reset procedures

Procedure 1:
1)disconnect nuvi from external power
2)Flip up GPS antenna
3)Press the reset button
4)Connect nuvi to power source. The nuvi should turn back on and operate normally


procedure 2:
1)Hold your finger on the upper-right corner of the nuvi's screen while you turn it on. keep your finger until the pop-up window appears
2)Touch YES. All factory settings are restored. Your recent selections and audio bookmarks are also deleted

There is a transient diode across the switch. Most likely it's shorted, casuing the symptom as if you were holding down the power switch and never letting go. I've seen and repaired this before.

SOURCE: I have nuvi 650. It is

Here is the procedure how I find it:
1. Power OFF your Nuvi.
2. Press and keep holding the most right upper corner of the LCD screen
3. Power ON your Nuvi but DON NOT release your finger either from Power button nor from LCD screen (keep both pressed until the procedure ends)
4. You will notice Nuvi boots in Pre-Boot mode. Now quickly connect your USB cable. Prior to that make sure you have the latest Garmin USB drivers installed on your PC (it comes with MapSource software)
5. If you managed to connect your USB to your Nuvi when it is still in pre-boot mode, you will see that Windows recognizes a new device - "Garmin GPS unit" and starts searching for drivers. Nuvi after a while turns the pre-boot mode off, but nevermind, finish installing the windows drivers. If your are using XP just click "Automatically install driver software" and when it says "Your Hardware is ready for use" you can unplug your Nuvi.
6. Drag the "nuvi_sys.rgn" file over "Updater" and select USB.
7. Now repeat steps 1-4.
9. Updater will recognize the unit then you can press Update button
10. Once the "Loader" text appears on your Nuvi, you can release your fingers from LCD right upper corner and from Power button.
11. Wait until update finishes, then disconnect your Nuvi.

If this isnt work, I can offer two suggestions:
1.- If Windows doesn't recognize your Nuvi, then reinstall the usb drivers that can be downloaded from Garmin's website.
2.- If you can get the computer to recognize the Nuvi, run Webupdater and reinstall the firmware even if you already have the latest version.

The Garmin website has USB drivers (for all Garmin GPS units) here: garmin.com/support/download

Hope helps.

Updating maps on garmin nuvi 1390t. Won't take 4g/sdhc card


You are correct. The 1390t works with microSD cards. While microSDHC cards will fit into the slot, they are electronically incompatible.
You need to use microSD cards 2GB and smaller.

Garmin nuvi 660 goes into pre-boot mode, then loading, then loading software, then back to pre-boot mode and keeps looping through the 3 steps, and it won't shut down

Charging doesn't display map when charging


I learned that with the unit off - hold the on button down - don't release it. A PRE-BOOT MODE message will appear at the bottom and may flash. Continue holding down the start button. The first time I did it a series of dots came on the screen and I was instructed to touch each one. After that it started as normal. I plugged into a wall charger and but git the pc and nuvi icons again. I repeated the process - holding the on button on and let the PRE-BOOT MODE appear and kept holding but this time a different message came on and then the PRE-BOOT MODE appeared again. I let it go and took the unit to my car and plugged it into the Garmin car charger and it worked as it used to - normal. However, when I plugged it back in the house to the wall charged I got the pc and nuvi icon again. It appears that I am using the wrong wall charger as a previous writes stated. But the nuvi still worked in the car plugged into the nuvi charger. I hope this helps.

In case it is a software problem try this and see if it will fix it......follow these steps.
1. Power off the unit.
2. HOLD down the power button and you will see "Pre Boot Mode" appear on the lower part of the display. KEEP HOLDING the power button down and the display will flicker, do this until the pre boot mode message disappears. This seems to take a long time (60 seconds at least).
3. Once the pre boot mode message disappears release the power button and your device will perform some activites to try recover from the problem.

Stuck with pre boot mode on screen


"Will not turn off, stuck on with display saying 'pre boot mode'. Does nothing but this - please help!"

This indicates that the on/off switch is shorted out. You can duplicate this problem by taking a working Nuvi and keep holding down the on/off button when turning it on. It will stay in this mode until you let off on the power on/off button.

Are you running this unit while it is charging? Does the Nuvi 660 have a sufficient charge?

Try to do a hard reset on the unit.
