instructions for using this file on your Nav unit.

Part A – Internal Memory if you have more than 2.6GB free

1. Connect your device to the computer.
2. Go into the Nuvi files located in the Garmin folder and backup
the file named “gmapprom.img” to your computer.
3. Delete the “gmapprom.img” file from the device.
4. Rename the file you downloaded "gmapsupp.img” to “gmapprom.img”
5. Copy the unlocked “gmapprom.img” file that you renamed into the device.
(these copy proceedures could take up to 45 minutes to accomplish)
6. Restart your device and check your map info via : Tools>Settings>Map>Map Info.
Why the renaming?
This must be done because this is not the primary mapset as it is being used from the SD card. The primary mapset is the one on the GPS’s internal memory.

Part B – SD Card

1. Get a 4GB SD card (NOT SDHC for old unit) and format it FAT32

2. Create a folder on the memory card called “Garmin”

3. Copy the downloaded “gmapsupp.img” file into the Garmin folder on your SD card.

4. Insert the SD card into your Garmin GPS, and browse to your map information on your Garmin GPS and you should see the new maps selected. This can be found on the device via : Tools>Settings>Map>Map Info.

5. Deselect the mapset that's out of date.



So - what are the verdicts, are this a real 2017 map? Since it is just april 2016 I'm sceptic.
FYI great torrent. These are the 2017 Maps I can Confirm Working on my nuvi2455LMT. Keep Seeding Thank you
Didn't show on my SD card on an old Nuvi 350. Load back my 2014 gmapsupp map and everything came back to normal. Guessing it isn't unlocked as stated
If this is unlocked, the map are invisible on my sd card
It works. Rename file to gmapsupp.img.
Thanks a lot bro.
works on nuvi 200 thanks
did not have to rename anything just drag and drop in to the gamin folder on the sd card works on the nuvi 200 thank again
I don't believe this is unlocked or if it is it's not universally compatible as past updates have been. Haven't had any issues with past maps. This one does not open in a Nuvi 660 regardless of file name gmapsupp.img/gmapprom.img or file storage location. Standard error about detailed routing not available.
Worked great on my Nuvi 7 series
Thanks. Problem with older Garmin units like Nuvi 660 is that they cannot read a map larger than 2GB. Metheguy, any chance you can break the map into two files, like USA in one map and everything else in the other map?
Worked fine for me on the Garmin nüvi 255W, which is pretty old. I used the SD card method, and it was an SDHC even though it says not to use one with older models. Did not have to rename the file either, just copied into folder like the instructions say, and that was it.
Tried for fun to update my OLD streetpilot C330. It had already a 4gb SD fat32 (not SDHC) with a old map. Followed the instructions. Works like a charm.
I followed the instructions for the SD card and updated my older 255W just fine, thank you!
