for what nuvi ?


The New Garmin Series (1xxx/2xxx/37xx)

In this devices you will find built-in maps in .System folder, this is a hidden system folder and you have to enable the view of this folder in:
Tools\Folder Options\View – Select Show hidden files, folders and drives
Tools\Folder Options\View – Uncheck Hidde protected operating system file (Recommended)

To update this devices you can:
1 - Replace the original map (gmapprom.img) with the one downloaded, you can rename the downloaded map in gmapprom.img if it is named gmapsupp.img
2 – You can create a folder called Map in the root and put the map file inside. The files in Map folder can be renamed as you wish and you can put more than one map in this folder.
Example: “X” is your Garmin driver
X:\Map\gmapsupp.img
X:\Map\Europe.img
X:\Map\NorthAmerica.img
X:\Map\XXXXX.img

You can do the same in SD card
SD:\Map\gmapsupp.img
SD:\Map\Europe.img
SD:\Map\NorthAmerica.img
SD:\Map\XXXXX.img
3 – You can use the Garmin folder in SD but you can use only one map, named gmapsupp.img


Other Garmin Devices

In other garmin devices is not present the .System folder , all the maps will be inside Garmin folder, the same here gmapprom.img map is the original pre-installed map
To update this devices you can:
1 - Replace the original map (gmapprom.img) with the one downloaded, you can rename the downloaded map in gmapprom.img if it is named gmapsupp.img
2 – You can use the downloaded map named gmapsupp.img just copy inside Garmin folder.
3 – If you want to have more maps in your device you can rename maps file in:
gmapprom.img (original map/ or renamed new map)
gmapsupp.img (2° map)
gmapprom1.img (3° map)
gmapoem.img (4° map – can’t be unselected)
devices with 3D buildings support, can rename in
gmap3d1.img (5° map)
4 – Using a SD card
Format in Fat32 your SD card and create a Garmin folder. Copy the gmapsupp.img inside the Garmin folder. You can use only one map in SD card.
You can have 2 maps named gmapsupp.img one in device and one in the SD card. It can help if you can’t put a full Europe map and you need a <2GB map. Copy the big one in SD and the rest usually a small file in Device, go in Setting\Map\Info and select both maps this way you will have a full coverage of Europe.

It is a nuvi 200.

Can I just rename the gmapprom to gmapsupp and put it in the Garmin folder?
