I had the same problem. What you do is place your finger in the lower right corner where the green button would be and cut it on. When the prompt comes up, click yes. when the no detailed maps comes up again, hold down the green button again. You should then be able to upload the maps.

SOURCE: 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.

You can download new maps..........free......................but..........

I had this problem last year with my garmin 200 and when I called they said that I was out of the 60 day time window for a free map upgrade but they would give it to me anyway. They gave me detailed instructions on how to download a new map free of charge but they didnt explain which selection replaced what I already had on mine.
As a result, I downloaded the wrong maps and have much less detail. Even though its the "2009" version, its less acurate than my old maps were. But its worth a shot, better than paying for them.

There are two different things to try.

Cannot unlock the maps in my garminedge 705. When i turn unit on message comes up cannot unlock maps


Information on unlocking garmin maps can be found at http://www.fixya.com/support/r6197735-no_detailed_maps_found_support_routing

There's more information there than you need since the article is about garmin nuvi satnavs that display a message "No detailed maps found that support routing" but part of the article deals with locked maps. The principle is the same for the garmin Edge but you'll need to skip to the part that deals with unlocking maps.

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.

I can't unlock my maps


Buy your map updates from Garmin, and Garmin alone.... then you can call on their excellent full customer support. They even supply you with an unlock code when you purchase maps direct from them as part of the deal. (these numbers will be recorded with Garmin, so contact them if you lost yours).
If you download maps from 'shady' sites, you get shady programs too.
Some maps downloaded have been found containing trojans to send details of your linked bluetooth products (phone details, computer details)

Hope this helps.
