If you had lifetime updates you just need to run the latest update, otherwise you will need to but an update to get it fixed. One time should be enough 49.99. Sometimes on sale though.

Contact Garmins Tech support hot Line they will walk you through the process and if they can't fix it over the phone they will send you a disk that will completely fix the "NO detailed maps found that support routing" I have contacted them with the same problem and the disc was free of charge.

SOURCE: 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.

This is an indication that the map or map unlock key is either missing or corrupted. If you have registered your unit with Garmin, try connecting to your PC and try downloading the map again. More info on missing maps can be found here:

No detailed maps found that support routing


Please connect your Nuvi up to a PC and look to see if you have the map file "gmapprom.img" in the Garmin directory. The file should be around 1.5 to 2 GB in size. If the file is missing you will need to replace it. If you have registered your unit with Garmin, you may be able to log into your Garmin account and download the map file again. If you can't, then you will need to send the unit to have the map file restored by a service shop. More info on missing maps can be found here:

I tried to update my new Garmin Nuvi 255w. It now reads as follows, No detail maps found that support routing. The nuvi cannot be used without them. I have a ABI and to help me even to get home is hard....


There are 2 possible reasons for this. The most likely is that the map is not selected. Go to Tools, Settings, Map and press Map Info. Is the map ticked. If not press it and it will tick. The map should then work.

The other reason is that the map may be locked. The instructions for unlocking the map are at http://www.garmin.com/garmin/cms/site/us/support/searchsupport?search_key=nuvi%20770

Garmin nuvi says, "no detailed maps found to support routing."


I am very sorry to hear that you are having problems with the unit. You
may need to switch the unit on and press and hold the centre of the
screen until the message ?No detailed maps? message disappears.

If your map detail is missing, then the map information may have been
disabled. To check to see if the mapping has been disabled, follow the
steps below:

From the Where to? and View Map page, touch the Spanner icon, settings
(Tools).
Touch Map.
Touch Map Info.
The unit should display the name of the map that is loaded to the unit.
The box in front of the map name should have a tick in it. If it does
not, touch the box to place a tick in it.

Then please test by searching for an address.
