Hello once again. You folks helped me with a cell problem, I hope you can steer me to the correct link or best advice. Again I have read the discussions, yet I have not heard about a map that will not only show the major highways with identifications, but the unmarked roads, some, gravel, some dirt, but still widely used. I know about a Garmin with a downloaded app, and I unfortunately have a Tom Tom. Yet, if that app that you would load into a Garmin, might just be the ticket if it indeed ID's those unmarked roads. Again, I look forward to your learned advice.
