Harmon nuvi 1300 won't go into preboot. I've tried everything I can imagine (power on touching each corner) none working even center. Tried holding the power button, loads up to garmin then powers off

Pre-boot mode is accessed by powering off the device and touching the left upper corner of the screen, while plugging in the USB cable into the unit with the other end already inserted into the USB port of a PC. Please note that pre-boot mode has a time limit and does not stay on indefinitely.

Garmin 1340T boot loop issue. The unit


Unfortunately, there isn't an easy solution for the Nuvi owner as it requires a custom piece of firmware to flash the unit to make it at least boot. This problem is often caused during a failed firmware and/or map update.

It sounds like a file was corrupted. Sometimes it is better to connect the unit up to a PC, delete the old map and then proceed to install the new one. There are so many issues with memory space causing failed downloads and corrupted files.

If the map file is missing, the unit will boot-up OK, it will just say "Map data unavailable" but if the map file or associated map files are corrupted, it can cause the unit to crash. Your PC won't recognize the Nuvi because you have the reach the main screen before the data communication mode routines are accessed.

We've had some success in restoring some of these units by flashing a "fix" firmware in "pre-boot mode" that doesn't try to load the map or map associated files. This should then allow the unit to boot. Once the unit boots, Windows will recognize it and then you can copy a map over to it from the PC. Reboot the unit and then flash it with the standard firmware.

Upon turning my Garmin Nuvi 1300 on it sticks on the screen that says "GARMIN".......Loading Maps. It never goes past this screen. I have had this unit since the end of December. It is fully charged and I...

A Garmin Nuvi 1300 that won't start, freezes on 'loading maps,' or is acting erratically is symptomatic of having corrupt firmware.

To correct this, I recommend backing up your favorites, clearing all user data, and if it still is stuck, then updating your Nuvi firmware.

Follow these three steps to take to get your Garmin Nuvi 1300 running like new:

  1. Back up your Favorites.
  2. Perform a Hard Reset.
  3. Download and then run Garmin WebUpdater to replace its firmware / system software.

I hope that helps.

My garmin nuvi 260 will not go past the loading maps screen

There is a corrupt or missing file associated with the mapping thats causing it to lock up. When that file is missing, your Nuvi never gets to the routine for communicating with your PC. That's why your PC can't detect it.

I've fixed this problem before. The unit must be placed in PRE-BOOT mode, forcing Windows to recognize it and then using a specific program, reflash the firmware to an older version that doesn't care that the file is missing. The unit will then boot properly and you'll regain detection to the unit in Windows. Then you can repair/replace the missing files and then reflash back to the latest firmware.

Yes, its a pain and not an easy process to the novice.

My nuvi 265w is freezing up or will not boot up past the Loading Maps screen.....boot

remove your SD card from the device and see if it passes boot screen and tells you that you have no maps
in that case your SD card is dead and you need to obtain new maps from garmin
if it still looks bad regarding booting - your device is faulty - so if still under warranty - send it to service
