Says no detailed map etc etc. Press screen until it disappears. press tools, then settings,then map. no map info available. what is the bootloader?
Plug your nuvi into your PC. Go to the Garmin.com website and log into your account to see your map information. You can go to your account and see the map downloads and reinstall it from there. Or you can download their software "Garmin Express" on your PC. Run the software while your Garmin is plugged into your PC and it will check for any updates for you.
The map is either corrupted or missing. Connect to PC via USB port, look in Garmin folder on unit for gmapprom.img file or on SD card for gmapsupp.img. If either are missing, then the map needs to be replaced.
The bootloader looks on the unit to see if an update has been put on the unit. If so, it flashes the update to the unit and forces a reboot to execute the new update. More info on lost maps can be found here:

SOURCE: GARMIN NUVI 200 SAYS NO DETAILED MAPS FOUND THAT SUPPORT ROUTING
I was having the same problem. NO DETAILED MAPS FOUND SUPPORT ROUTING & SO ON. I called Garmin this morning & I thought I would be on the phone forever with the gentleman. But I was on for less then 10 minutes. The guy asked me to connect my Nuvi to the computer using a usb cable, then asked me to go into my computer & look for the device/drive that my Garmin is using. He then prompted me to open the file that says Garmin & asked me if there was this file that said gmapprom.unl. I told him no & then he sent me the file through an email. I had to open the file & get it into the Garmin file. Then he asked me to disconnect my Nuvi from my computer & it started right up & the problem was gone. If you do have the same problem I am willing to email you the file he sent me if you would like because there is no possble way to get the file from just searching on the computer. Let me know.

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.

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.
