Regardless of the address or point of interest you are looking for, your garmin tells you that there is no result:
try to go to the "Tools" menu, after select "settings", the "map", then "info". In this menu you can see the version of maps installed. Be sure to check at least one map, otherwise you will not find anything with your gps!
If your gps is frozen, try the reset button: there's no standard place on a nuvi, check in the manual.
