Update: I just checked - TomTom uses TeleAtlas - a company that mostly specializes in European mapping... if I remember right, Navteq mostly does the big auto manufacturers built-in gps maps... at least, when I go to their web site they list them all...
Also, TeleAtlas lists Mapquest as one of their partners, so see if you can do a mapquest on your GF's house... if it shows up there, maybe you just need an updated map from TomTom?
