Though these devices are compatible with SD cards larger than 2GB, any individual file on an SD card or the device's internal storage cannot exceed 2GB in size, or the file will not be seen by the device. This is most commonly a problem with European mapping but will occur with any 2GB file. The above device series are not compatible with the supplemental mapping of Europe for this reason.

Firstly, update your firmware to latest version 6.30 if it's not already running that version. To check, press Tools>Settings>System>About.

1. IMPORTANT. Ensure your unit has a fully charged battery.
2. Fully read the preamble above if you haven't already.
3. Make a full backup of your file system including the .System folder, or at least do a backup of your favourites if you wish to restore them. To show hidden folders see [Please Register or Login to download file] .
4. IMPORTANT: Either HARD RESET the unit, or CLEAR NONVOL. Hard reset is done by holding the lower RH corner of the screen while turning the unit on, follow the prompts. Clear Non-volatile memory by pressing the 'Speed' field on the map page, hold the centre of the Speedometer for ~6 seconds, when the Diagnostics Page appears, press Developer Info>'Nonvol Available>Clear Nonvol. [Clear Nonvol is simply more comprensive than hard reset].

How to Do It:

1. Download the zipped file: Garmin.zip
2. Extract it onto an otherwise completely empty microSD card.
3. Ensure your unit is completely off. Place the card into your unit and turn it on.

You will see the alternating words 'Software Loading' and 'Loader' appear on the screen. Let the process completely finish and the unit reboot. Then hard reset or clear NV again.

Check that you have both 16_backup.bin and 41_backup bin in the folder microSD:/Garmin/Backup. If both are present the process should have been successful and you will have a new file named update.log in the Updater/xxxx folder [xxxx is your unit's HWID, e.g. 0972 for 13/14xx]. The log is simply a form of .txt file and can be opened with any text editor. The contents should read:
Parsing "rrgn,16,1:/Garmin/backup/16_backup.bin"
Success
Parsing "rrgn,41,1:/Garmin/backup/41_backup.bin"
Success
Parsing "xrgn,16,1:/Garmin/16.bin"
Success
Parsing "reboot"

Keep copies of both bin files [especially 41_backup.bin] in a safe place. 41.bin should have size of 4096KB. It is the most important region on your unit and contains important data specific to your unit. The information is encrypted, but if the region ever becomes corrupted, it can be restored from your 41_backup.bin

To use Junction View, you will need to obtain the relevant JCV file for your current map. The file either goes in the folder nuvi:/.System/JCV or microSD:/Garmin/JCV.
