    You can try this step that I found. If you tried loading other mapas try this.



    You will need to erase a file from the units memory. Connect your GPS system to your computer; go to start then ‘My Computer’, and double click on your device file (mass storage system), there you will see a folder named ‘Garmin’.

    In this folder are several different files, look for file named gmapsupp.img. Right hand click on this file and delete as this file is causing the maps to lock.

No map data available


The map may be unselected or locked. There's information at the link below on how to select your map. Go to paragraph 5. If this doesn't solve the problem start at paragraph 2 of the same link for details of how to unlock your map.

I have no maps on the screen its like i lost all the data. it says there are no roads near this start point. every thing else works mp3, settings, volume, bluetooth, etc.


it sounds like you may have just deselected the maps.

go to tools settings map then map info(bottom of the screen)

check that there is a tick next to your mapset if not just tap the name of the map and you should be sorted out.

No data available and no maps downloaded


it may just be that the maps are deselected. to correct this go into the tools/settings/map and then at the bottom of the screen in the middle you will see map info tap that and then at the next screen it will show you the maps which are installed if there are any without ticks just tap the box. tap ok and try again if. if there are no map choices then you will need to reinstall the maps on your unit

"No Map Data Available" - Garmin Nuvi 350


This is because your map file has either been deleted or corrupted and needs to be replaced. Please see this link for more info. Too much info to copy & paste here:

Map data availability


"I tried to load the new 2008 City Navigator but the update was interrupted."

You deleted your previous maps, therefore there are no maps on the unit. Try reloading the maps again and this time let it continue all the way to the end. It will take a couple of hours depending on loading all maps or only certain states.
