Many German car navigation systems (Audi, BMW comes to mind) have a map display which does not only show the driving directions, you can also see whats around you on the screen (big parking lots, churches, train stations, gas stations and other stuff). I love it, it really helps finding the nearest gas station before returning the car
I never have used Neverlost, but I plan to, so does Neverlost show gas stations or some additional info about your surroundings?
