It can show you arrows on where to turn by only when returning home to your starting location.
I've used it for driving around in foreign countries...you simply plot out where you want to go in advance, and pop it into the Garmin. It'll show you a bread crumb but no streets but that also means you're not purchasing new maps.
It's also how I explore new routes.
