[amsat-bb] GPS position

I know this sounds lame but anyone know where I can enter lat and lon and get my location. All my gps does really is give lat&lon which is fine, but all the things I have found you click on the map and it gives everything with grid but I want to do the reverse, so when I am driving around I can punch in my gps cooridnates and get my location /grid on the map.

Thanks for any help. :)
