We have a cheap GPS. Made a 2,000 mile trip from Indiana to Great Falls,MT. and did not use it at all to tell me where to go and when. Will be headed to Portland,OR. from here and will only use it to get to a site we have reservations at in Portland when I get real close to the city. Will be taking a different route back east and will not use it then either to tell me where to go and when. By the way we used some roads other than interstates coming out and will do the same going home. Just me.
