Check the SD memory card. There is a slider on the side of the card for locking to enable read-only mode. This slide should be up to enable read/write mode

I have lost all UK & Europe mapping - except for major roads. This was initially built in to unit. Have SD card for Australia & New Zealand - this works fine.


The maps are stored in specific mapset files with *.img extension in the flash memory of the GPS unit. Each mapset file contains one or many maps in it. Beside that, the Garmin GPS navigator can also recognise and load up one additional mapset file from SD card residing in the "Garmin" folder and named as "gmapsupp.img".

Here are the mapset files supported by Garmin Nuvi 255w GPS navigator:
  • gmapbmap.img - the default base map
  • gmapprom.img - the primary mapset
  • gmapprom1.img - the secondary mapset
  • gmapoem.img - the OEM mapset that cannot be unselect by user (if it exist)
  • gmapsupp.img - the supplemental mapset which you can have one in the GPS flash memory and another one in the attached SD card.
Therefore, the Garmin Nuvi 255w GPS supports up to 6 mapset files, including 1 in SD card. Normally new maps installed by the user will be stored in gmapsupp.img.

You will lost all the maps in the previous mapset file if it is overwritten by a new file with same filename. If you want to keep the existing maps, ensure that you store the mapset file with an unused filename (from the 5 filenames above). Alternatively, you can make use of special tools to merge new maps into existing mapset file.

You can view the name of your base map in Tools > Settings > System > About > Basemap.

You can view the name of maps in the other mapset files in Tools > Settings > Map > Map Info. There, you can tell the GPS to load the map by checking on its name, or not to use the map by unchecking it.

In case there are 2 or more non-overlaping maps available for the same location, the map with the highest priority number (defined in the map itself) will be used by the GPS.

Note that certain map which are locked by vendor need a 25 bytes unlock key stored in a *.unl file in the same folder and with the same name as the mapset file where the locked map is stored in.

In attempting to unsuccessfully download maps on Garmin for a NUVI 255W, I am now receiving an error screen on my Garmin: No detailed maps found that support routing. The nuvi cannot be used without them....


Ok I had same problem. Copy the mapupdater .exe file to another computer with internet access. Connect your GPS and then run the updater file. This worked for me. Good luck

This is because your map file has either been deleted or corrupted and needs to be replaced. Please see this link for more info. Too much info to copy & paste here:

Tom tom go 300 ''unable to store settings'' ''file access error'


Hi,
You might have the switch on SD card set to "read only" , This would stop your tomtom being able to write to the SD card ... hence , " unable to store settings " message . .... OR ... the folder where your tomtom wants to store the settings is corrupted ( on your SD card ) so it can't store them.... or similarly , the file is corrupted on the SD card ( maybe the card is damaged ) so the existing file cannot be overwritten . Check out all these possibilities before suspecting any hardware fault on your tomtom ..... GOOD LUCK

Hook the Tomtom using the USB cable to your computer. You should see the Tomtom drive under My Computer as a drive letter.

Backup all data from the Tomtom to a folder on your computer. Now select the Tomtom drive and right click, select properties, select tools, and then Check now. Allow the computer to fix any problems with the Tomtom drive. Once this is completed. Remove the USB cable and do a reset. Now turn on your Tomtom and it should work.
