I have a Garmin Nuvi 350. I solved the problem by purchasing a Glisson GPS antenna that plugs into the external GPS connector on the Garmin antenna.

SOURCE: Garmin Nuvi 205 keeps saying no maps available ???

First you will want to empty your recycling bin & clear your temporary internet files before re-downloading the Garmin_RMU_2010B.exe file.

Below is the remainder of the fix I received from Garmin support and it worked for my unit. Hope this helps.

1. Extract the downloaded file Garmin_RMU_2010B.exe using 7zip(7zip.org) or WINRAR.

http://downloads.sourceforge.net/sevenzip/7z465.exe 32 bit
or

http://downloads.sourceforge.net/sevenzip/7z465-x64.msi 64 bit
2. After extracting, the files should be available at the location where you extracted the files.
3. Go to the extracted file location. Click on the Windows folder.
4. Right click on the Setup.exe file and Click Create Shortcut
5. Right click on the Shortcut to Setup.exe file and Click Properties
6. In the target line add " -build_map_image 006-D0783-04 " at the end of setup.exe". For example the end would look like xxx\Setup.exe" -build_map_image 006-D0783-04
7. Click Apply and OK.
8. Double click on the Shortcut to Setup.exe the map file will be built. Leave the Window open till completion of all steps. 9a. Windows XP: Click on Start>Run, then type in %Temp%. Another window will open.
9b. Windows Vista: Click on the Start Button, in the Start Search, type %temp%. Another window will open.
10. The file is placed in subfolder named 006-D0783-04.
11. Copy the gmapprom.img file from the folder to the Garmin folder on the Nuvi. (Double click on MyComputer>Nuvi drive>Garmin folder) Overwrite the existing file.
12. The Nuvi should now have the lower 49 installed. If you have any trouble with this fix, or are not comfortable trying it please call our Software Support Department at 1-800-800-1020. Please be at a computer that has high speed internet access as we may need to log on to your computer to resolve the issue. Make sure you have the program extracted using the 7 zip program provided above. Hours of Operation Monday – Friday: 8 am – 7 pm Central time (closed holidays)

Can't unlock maps on garmin nuvi 255w after update


You can try to power down for hard reset(disconnect battery) and after connect again or reset to factory setting.

I have recently purchased nüMaps


Since you have (2) maps, North America and Europe, you will have (2) map files on the directory. They are:

gmapprom.img (North America map)
gmapprom1.img (Europe map)

Do you see both of these file names? Do you have unlock files associated with them such as:

gmapprom.unl (North America map unlock code)
gmapprom1.unl (Europe map unlock code)

These files should be 1 gigabyte or more in file size. If they are not, then they are possibly corrupted.

Cant unlock maps


I can help you reset and fix your Garmin Nuvi 265WT.

Getting stuck on the flashing Garmin logo, or a message about not finding any maps, are indications that the firmware / system software inside your GPS has been corrupted. Don't skip the hard reset step (or the backup step!)

There are three steps to take to get your Nuvi 265WT running like new:

  1. Back up your Favorites.
  2. Perform a Hard Reset.
  3. Download and then run Garmin WebUpdater to replace its firmware / system software.
Sometimes, a Hard Reset after the WebUpdate is what is required; that information is covered in the details through the links above.

I hope that helps.

I recently updated nt2010.20 map since then my nuvi 350 freezes while loading maps i tried reset, hard reset, preboot,when i connect it on USB i cant see device on my PC.is there any way to delete map...


NO!. THE MAPS CAN ONLY BE DELETED USING THE USB CABLE. GO TO GARMIN WEBSITE YOU MAY NEED TO DOWNLOAD THE USB DRIVERS. THEN TRY THE UPDATE AGAIN. IF THE MAPS ARE ON A CD YOU WILL ALSO NEED THE UNLOCK CODES AND THE UNIT SERIAL NUMBER.

Garmin nuvi 360 wont unlock maps


Master reset is after you turn on the GPS put a finger on the left lower corner rightaway and then keep the finger there, wait until it shows up the "Do you really want to start up in maintainance mode"

You are not able to use others nuvi's map on your nuvi 360, as each map must match with the GPS unit ID, to find out your GPS's unit ID, go to "Setting" tab on "System", tab on " About"

Can't unlock maps


What have you tried? without knowing anything else, one suggestion is to make sure you are using the correct unlock key number. There are at least three numbers located on the disk.
