We've used Delorme Street Atlas for over 20 years. It's excellent for preplanning a trip to go the way YOU want to go by inserting vias. We don't do interstates if possible and using the secondary roads to explore the country is excellent. You can preplan the trip without internet. Your route can then be transferred to a regular GPS for a heads-up for the driver. If the passenger wants a more detailed screen (like we do), the passenger follows along using a laptop and the Delorme GPS pod attached. There is no internet involved.
A regular GPS shows no detail. Delorme shows it all.
