The correct map for your 310 is the non-unicode NT which is will not be updated any more than twice a year now. Current map is 2014.40: [Only registered and activated users can see links. ].

I do not agree with you comment; I've got one of the first Zumo 660 devices which came out somewhere < 2010 in Europe.
I have pushed this NTU version 2015.20 from Mapsource over to my Zumo 660 and can see everything, same looks as with the usual NT versions maps AND i can use the search functions fully on my Zumo 660 device.
I have no idea what has happened between 1 year ago when I tried the same and now why it DOES work; maybe it's due to a firmware upgrade recently.
