Can't access Where to "Address" on my 2460.

I just noticed on my Garmin 2460 that when I try to add an address by tapping "where to" and then "Address", all I get is "No map data avaialble". I did a hard reset and I still get the same results. So now I can't add an addrss or search for an address. Anyone else have this problem? Any sugestions? Everything else seems to work perfectly,including my maps,
