    cannot get nuvi 200w to show map after connecting USB cable to register and download map update. Unit is reflecting message on screen that the unit has no detailed map info for routing and will not function. What can be done?

Soution:

1. Use Mapsource to find the unlock code for NT v8 (from Utilities->Unlock Maps...).
2. Using Notepad, edit gmapprom.unl file on the unit (under Garmin folder) to replace invalid code with the correct 25 character unlock code (no spaces or dashes) and hit Enter key and save.
3. Reboot.

Checking the unit:

My Garmin Nuvi 200 has a message that says No detailed maps found that support routing. The nuvi cannot be used without them. I just used this garmin a few hours ago, and it was fine. Now I can't get...


You need to call garmin to have them help you unlock your unit. It sometimes requires the 25 digit unlock code which they have on hand. 1-800-800-1020 I believe.

Unable to unlock new maps


Where did you download the Australian maps from? If from Garmin, contact Garmin for the unlock code. Maps have to be unlocked to a specific unit.

If you downloaded the maps from the internet, you will still need to contact Garmin for an unlock code.

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.

Unable to unlock maps for garmin nuvi 200 I am having trouble getting new stuff on my Garmin Nuvi 200. I registered it thinking it would let me download mapsource and it didnt. So then I got a pirated...


Here's a thought: instead of trying to install pirated maps which don't/won't work on your unit, how about actually buying the maps which are guaranteed to work. You will get a free copy of Mapsource on the disk with the maps of Europe.
