How do you reset the default home location in Apple Maps?

I've moved since I got my phone, and I updated my billing address and everything, but Maps still thinks I live at my old residence. This is really annoying when I try to get directions to go home and have to type in my address every time. I've already reset location services and my wifi, but there's nothing in Maps or the Settings that I can see that relates to my phone being associated with my old address. Does anyone know where/how to change it?
