Garmin nuvi 250 mapsource

I loaded my English maps from mapsource to my Garmin nuvi 250, creating file gmapsupp.img. (my default maps are Australian). When I tried to navigate in England I got "Unable to Calculate Route. No roads near starting point.", even though I could see my current location on the screen of the Garmin.. I was unable to use my GPS in England. Very annoying and frustrating. How can I fix this?

    I have the same problem with the Australia map on Nuvi 350. Both Australia and North America are on the same unit. Could this be the issue. North America works fine.

Thanks for the help. I managed to resolve the problem by installing the program on an external SD memory card.

Verify that you have the correct basemap for the country that you are in. There are two maps inside a new Garmin. The basemap which shows all the major highways and mapsource which shows all the street. If you don't have the correct basemap try changing 'Navigation' Advoidance to avoid highways and Toll Roads.

Garmin 1450 does not recognize memory card


What are you trying to put on the SD card? A map? If so, you need to create a subdirectory on the SD card called "Garmin" and the map file and unlock file should be named "gmapsupp.img" and "gmapsupp.unl".

Garmin Nuvi 1350 showing on screen "no map data available"


Shut off the nuvi.

Remove any memory card (if equipped) from your nuvi.

Plug the GPS into your computer via USB cable.

Open the Garmin "drive" icon in "My Computer"

Navigate to the x:/Garmin directory or "folder" (where "x:" is the drive letter assigned to your Garmin). Locate either map files set(s) named: gmapsupp.img or gmapprom.img.

Some units store map files in the hidden x:/.System directory instead. To view the .System folder and contents, you must direct your computer to display both the "system" and "hidden" files.

If you lack large files named either gmapsupp.img or gmapprom.img (about 1 GB or more); your maps are missing from the internal memory of the nuvi and will need to be reloaded.

If you pulled a memory card above, reinsert it and check the directories for the same gmapsupp.img or gmapprom.img files. If they're not present there, the maps should be reloaded.

I hope this helps

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.

Gps has lost its maps, screen says can't unlock maps


There several reasons you may receive the message Can't Unlock Maps on your nuvi or zumo device.
  • Can you press OK and get to the Where To/View map screen?
  • Did you load maps to the unit using the MapSource or MapInstall program?
  • Did you load maps to an SD data card?

If one of the points above applies to you, please follow the steps below to clear the Can't Unlock Maps message:
  1. Remove SD card from unit, if applicable.
  2. Plug the unit into your computer with a compatible USB cable.
  3. Open MyComputer/Computer icon. (Mac users skip this step.)
  4. Right-Click on the Garmin drive and select Open. (Mac users can locate the Garmin drive mounted on the Desktop.)
  5. Open the Garmin folder.1
  6. Locate a file named gmapsupp.img
  7. Right-Click and delete file named gmapsupp.img
  8. Safely disconnect your unit from your computer to see if the Can't Unlock Maps message is gone.

1. Nuvi 1100/1200/1300/1400/1600/3700 and Zumo 665 users will open the Map folder instead.

*If the gmapsupp.img file does not appear in the Garmin folder, please create an unlock file for device.

Garmin Nuvi 255w won't start up. tries loading maps and then goes in a continuous circle. acts if not charging. tried reseting and charging with wall charger and car charger


You should try to manually delete the maps (after a backup ) on the device , power cycle and retry sending the maps from MapSource or the Software CD from the manufacturer. The map is a single folder onto the device (eg. gmapsupp.img)

Garmin Nuvi 200 Maps Disappeared


Hi,
Hope this helps!

I wanted to add maps to my 250W. I found the maps I wanted on a Torrent. However, many searches around various forums never revealed how to install these. Found the following through reading and experimentation.

1. Downoaded map image file GMAPSUPP.IMG. Download also gave me "Use code XXX when generating unlock code for maps"
2. Downloaded Garmin Unlock Generator 1.3 by JetMouse
3. Looked on my GPS to find the UnitID
4. Entered the UnitID into Garmin Unlock Generator. Ignore the GM XT device unlock code and the top Generate button.
5. Selected Map Product as Custom and entered the code given for the downloaded image file.
6. Hit the bottom create button to generate a 25 digit code.
7. Download Img2Gps and run
8. Click Load Folder to load the image file. Select the tick next to it.
9. Check the Use Unlock Key option and paste the 25 digit code in.
10. Load a blank SD card into your Garmin
11. Connect the Garmin to your PC using a USB cable. You should see two dirves in windows: one is the Garmin and the other is the "Removable Disk" SD card.
12. Create a folder called "Garmin" on the SD card
13. Select Folder/Card in Img2GPS
14. Click "Copy Maps". Select the folder /Garmin on the SD card. You may need to click copy again.
15. Upload will take a while.
16. You should now see a file GMAPSUPP.IMG on the SD card in the /Garmin directory.
17. Create a new text file called GMAPSUPP.UNL in the same directory (make sure it does not have a hidden .txt extension).
18 copy the 25 digit unlock key into this file.
19. Close the file.
20. Disconnect the Garmin.
21. On Startup it should load your original maps and the new ones.

Can not download map update 2009 from garmin pls help me


TO GET 2009 MAP IS NOT EASY! Software update is, from the Garmin site you can update software easily BUT THE MAP... you must purchase for $69.99 OR if you're a technical person who knows the following instructions you can save some $$$

search torrent for
"CNNANT2009-1 MapID 396"
under torrent sites, you know what you're doing.

Use these instructions if you have downloaded it.

Download these first:
cgpsmapper.exe
gmaptool.exe
MapSetToolKit.exe
and MapSource where u can directly get from Garmin site
http://www8.garmin.com/support/download_details.jsp?id=209

Create these folders on the root drive: (I will choose one to make things easier, you can change)
C:/grmtmp
C:/grmtmp/extract

Connect your GPS to USB, and BACKUP then remove
X:/Garmin/gmapprom.img and gmapprom.sum (may be gmapsupp.[img+sum]) approx. 1GB

1) Copy gmapsupp.img from this torrent to C:/grmtmp;
2) Extract gmaptool.exe, cgpsmapper.exe and mapsettoolkit.exe to C:/grmtmp/extract
3) Open a command prompt, and navigate to the extract folder ("cd/grmtmp/extract")
4) Run "gmaptool -S ../gmapsupp.img" Note that is -(CAPITAL S), lower case s is for different option
5) The above will extract files, you will get some warnings about 10 degrees. Ignore them.
6) Run "cgpsmapper mapset00.mp"
7) Run "MapSetToolKit"
8) In MapSetToolKit, press "Install A Existing Mapset"
8a) TDB File: "mapset00.tdb
8b) Overview map: "mapset00.img"
8c) Registry name: "WhateverYouWant" (I did "Grm2009.1Update")
8d) Leave TYP files blank, and hit "Install"
9) Close MapSetToolKit and run MapSource
10) Ignore any requests to unlock map, not ready yet.
11) Go to "Utilities-Get Unit ID" and Find Device with your GPS plugged in USB. Write down Unit ID.
12) Run Garmin Unlock Utility, Enter that Unit ID at the top.
13) Select under "Select Map Product"
14) Ender 396 for the FID/MapID, use the Generate button to get 25char code.
15) In MapSource go to "Utilities-Manage Map Products"
16) Go to "Unlock Regions" Tab, and hit "Add...", enter 25char code, comment optional
17) Now on the main MapSource screen, type 'm' to enable map tool.
18) You should see a large white rectangle, with rectangle outlines (these represent NA maps)
19) Click and drag to select them all, you can click "Map Set Name" if wanted.
20) Click the "Send to Device" button. Wait an hour. Enjoy.

Having a problems with uploading maps to gps


HOW TO INSTALL CN NA 2009NT ON A STREETPILOT C330
The CN NA 2009 NT mapset is too large to be installed in the C330 without putting part of it onto an SD card. My recommendation is to build an image file containing the lower 49 states, PR & the USVI and upload it into the internal memory as a new 'gmapprom.img' file, and then build a new 'gmapsupp.img' file for an SD card containing Alaska & Canada.
Start the process by using MapSource to create a new 'gmapsupp.img' file, choosing the lower 49 states plus PR/USVI. Make sure that the total mapset size is no more than 975MB (930MiB) MAXIMUM. Anything that's very much larger will cause the installation to fail, due to insufficient internal memory. Note: Even though MapSource lists the mapset size in "MB", it actually measures it in "MiB". DO NOT EXCEED 930.0 MAPSET SIZE AS LISTED IN MAPSOURCE! (Can you get away with "just a little bit more"? Yes, you can, but why push it when you can simply put the rest on an SD card? Otherwise, you'll spend 40 minutes uploading it to your C330, only to have it fail at 99%. No fun... )
After selecting these maps tiles, choose 'Transfer > Send to Device...', but do NOT select your C330 as the destination for your new 'gmapsupp.img' file; instead, choose to send it to a blank 1GB (or larger) SD card plugged into one of your USB ports by way of an appropriate adapter (or to the 'C:\Garmin\' folder on your primary hard drive if you're running a specially-modified MapSource executable). MapSource will automatically create a 'Garmin' folder on your SD card and create your new 'gmapsupp.img' file within it.
Once you've successfully accomplished this task, copy the new 'gmapsupp.img' file to your hard drive's 'C:\Garmin\' folder (unless that's where you sent it in the first place, as noted above), then re-name it 'gmapprom.img'.
Next, repeat the process, selecting Alaska plus all Canadian provinces instead. Do NOT select any of the U.S. map tiles you selected the first time around. Capiche? This time, however, after creating the new 'gmapsupp.img' file on your SD card, do NOT copy it to your hard drive and do NOT re-name it. Just plug your SD card into your C330.
Finally, we're almost ready to upload the first file you created -- now called 'gmapprom.img' -- into your C330. First, we have to make sure you have a copy of Garmin's WebUpdater package installed. Open your 'C:\Garmin\' folder. Is there a 'WebUpdater' folder there? Yes? Great! Look inside and you should see a file named 'WebUpdater.exe'. If you've got it, you're almost there.
You don't have WebUpdater installed? Go get it and install it; it's a free download from Garmin. I'm using Windows XP; be sure to get the Windows version that's right for you. (To the best of my knowledge, this procedure does not work on a Mac. Sorry... ) http://www8.garmin.com/products/webupdater/howtoinstall.jsp
Now that you've got it installed, do the following:
- Right-click on an unoccupied area of your Windows Desktop; when the menu pops up, choose 'New', then 'Text Document'.
- Double-click this document; this will open up a brand new blank document in NotePad (or whichever text editor you've chosen).
- Copy and paste the following line of text into it...

C:\Garmin\WebUpdater\WebUpdater.exe /upload_file rgn=49 path=C:\Garmin\gmapprom.img -autorun usb /i

- Select 'File > Save' then 'File > Exit'.
- Re-name the file to 'C330_Map_Update.BAT'
- With the C330 connected to the PC by USB (your drivers have already been installed previously, yes???), double-click on your new 'C330_Map_Update.BAT' file.
- Sit and watch as the WebUpdater application opens up a command-line window and copies your new 'gmapprom.img' mapset into your C330!
- It will take approximately 35-40 minutes if all goes well.
-Don't forget, you'll need to have previously entered your 25-character unlock code into MapSource. That unlock code must be specific to your C330; just because your Nuvi's unlock code allows you to create mapsets in MapSource doesn't mean that those mapsets will work in your C330!
