Our use case is the 'around town, everyday driver'. About 30-50 miles per day. I know where I am going and rarely use the nav. I have not had the cell nav drop out in the greater Houston area. Even our trip to Austin did not have any nav issue. We take 3-5 long trips per year (2-3k miles per trip), but that is in our 45-foot motorhome, pulling our RAM pickup for local use.Hmmm maybe now’s a good time to get out more and explore.
