Is there any reason you wouldn't want to link your address to a Google Maps url? I think it's a pretty standard experience on the web for an address to link to a map. There's always the discussion about how to remove blue links on phone numbers and addresses, etc.. my suggestion is just link the thing and style it how you want. I realize there are other words that will turn blue in various inboxes and devices. You could also personalize the map url based on location or preferences if you have multiple retail stores.
