    Patch file didn't work. Had to go to Garmin and use Restored Map Available for your nüvi® 255W. I was missing an ini. file and second try the maps reloaded.

When i turn my nuvi 255w on i get the fallowing message. no detailed maps found that support routing. the nuvi cannot be used without them.

It sounds like the map file is missing or corrupted or the route you want to use is just outside of the covered area of the normal maps.

If the unit is less than 60 days old you can update the map by connecting it with the usb cable to your pc and going to garmin and then running the update. Past that they want you to pay.You can download free map files for certain locations to your sd card. The localized maps ie just for one country or portion of it have much more detail than the stock internal map. You may need to look at purchasing one of those to get enough detail. I just used one for Fiji and it even had all the back streets on it. If you are in Canada or the US or Europe they will even have much more info.

I would call the toll free garmin support number and run the problem down to them. They can check your serial number and let you know the options. They should be able to tell you what map to use/get if thats needed.

In attempting to unsuccessfully download maps on Garmin for a NUVI 255W, I am now receiving an error screen on my Garmin: No detailed maps found that support routing. The nuvi cannot be used without them....

Ok I had same problem. Copy the mapupdater .exe file to another computer with internet access. Connect your GPS and then run the updater file. This worked for me. Good luck

I have a Garmin Nuvi. The screen shows no detailed maps found that support routing. The nuvi cannot be used without them.

You need to connect your GPS to your computer and reinstall the basic operating system from the Garmin site.

sounds like the map folder in the gps software got corrupted. you will have to connect your device to your computer, get on the Garmin website, and let the garmin site update your device. Once updated, it will re-install the correct folders and maps to their proper place. the gps should work as before after that.

You must call Garmin at 1-800-800-1020 they will walk you through plugging in nuvi to your computer (must have usb cord) and it will upload then go to my computer and choose garmin drive then click garmin folder and either find the folder they say or make new one like I did with the guy on the phone and put in code. The only information needed is the numbers on the bottom of the device.... super fast fix!
