New map not displayed on Garmin 200

I have a problem with a 200.

I installed map via MapInstall, in unit in "Map Info" it shows but I cant see any street in "View map".

I tried with NT and NTU versions, same issue.

Please help!

Sorry but wich exactly garmin you have? You mean Edge 200? and the maps that you tried are from where ? from here? If the maps are from here unlocked ones and your device cannot see them maybe you need to pacth your firmware.
