Here we’ll update a Garmin GPS device when you have only one map installed.
Check maps installed on GPS
Through the menus of GPS we look at the map name that we’ve installed in the GPS. Depending on the model is accessed in a certain way.
Ie. Garmin 1300:
Tools; Settings; Map; Info
Enable “Show hidden files”
This is because the vast majority of Garmin GPS have the maps inside the hidden folder
:\.System. To “see” the hidden files have to do the following:
- If is hidden, it’s necessary to show the command bar, that’s: File-Edit-View-Tools-Help. To make it appear temporarily in Windows Explorer, have to press the key [Alt].
- Click on “Tools1; Folder options2“, tab View3.
- Click on Show hidden files, folders and drives4.
- Uncheck Hide extensions for known file types5.
- Uncheck Hide protected operating system files6. There will be a warning to which will answer “Yes”.
- Click onOK7.
Locate the map
The maps are in the
:\.System folder that we have shown, that being only a map, there’re only two possible names:
gmapsupp.img. There may also be maps in the
On maps I offer only Europe and Iberia (Spain-Portugal) in both NT and NTU.
To install the map just have to transfer it to GPS, the map has the .IMG extension so if he’s in a .RAR have to extract it first.
- Connect the GPS to computer. It should appear as a removable drive just like with the pendrives.
- Move the .IMG file to the
:\Maps) folder. Following the Garmin name nomenclature, the most appropriate name for the map as a single and main map is
gmapprom.img. If the previous map exists
gmasupp.imgmust delete it before and if it’s as
gmapprom.imgdirectly we’ll overwrite it.
- Disconnect the GPS from computer, and turn on
- Confirm that it has taken the map right, as we did before to know which map we had installed on GPS.
Enjoy your trips!
