I'm getting a Garmin nuvi 55LM for my wife (who gets lost very quickly). I'm wondering whether there is any point in trying to supplement the map information with additional images or topographical info. (I don't know how to do that, but I've gotten the impression that there are ways to do it.) There might be some reason to put in more such info if any of it becomes visible on the display as you're driving along, looking at either the where-am-I display or following a route to some destination. However, if you only see it if you enter some special commands, in planning a route perhaps, it would not be helpful to my wife (because she'd never plan a route).
