Maps for most GPS devices are updated several times a year. Your map is from 2010 and should be updated. You can go to the garmin site and pay to download and install upgraded maps or do a google search for map upgrades and you'll find some services offering lifetime upgrades for a few dollars more than the Garmin one time upgrade. I did this and have had no problems updating the maps on my Garmin Nuvi 250.
To update your nuvi, all you need to do is to connect your nuvi to an internet connected computer and the updates will show on the lower left of your computers screen, click on it and it will update it with the latest software version and maps.
You can also go to your nuvis website and search for latest updates. Just click on the map link and a list will pop up under the map link, select update maps if it is maps you want to update. It will ask you to choose your device from a list, after choosing your nuvi 255w then it will show you the latest maps for your gps, but you have to install its plug ins first.
That is how to update your gps.
You should try to manually delete the maps (after a backup ) on the device , power cycle and retry sending the maps from MapSource or the Software CD from the manufacturer. The map is a single folder onto the device (eg. gmapsupp.img)
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.
To my knowledge you cant remove preloaded maps,but word of advice when purchasing other maps,get them on a Memory Card instead of preloading on your GPS,reason being,if you deciede on a different GPS in the furture you can then use the same maps which are on the Memory Card.
