The solution to the "No detailed maps that support routing" problem can be found at http://www.fixya.com/support/r6197735-no_detailed_maps_found_support_routing

To set up a map on the micro SD card you can follow the instructions on http://www.fixya.com/support/r5628920-update_garmin_satnav_maps Don't download directly to the micro SD card as it won't be recognised by your satnav. Download to the computer and install from the computer to the card as described at the above link.

No detailed maps found that support routing. The nuvi cannot be used without them. No maps can be brought up? turn on and I get the message above


Whenever these devices start acting up, I recommend performing a hard reset of your Gamin Nuvi 205. Also, use Garmin's WebUpdater service to make sure you have the latest software on your device.

I hope that helps.

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.
