There are still large areas of the USA with limited to none cell service. On trips out west, I found this is when we need NAV the most. Before our Clarity Touring, we used (and still do) a cheap garmin (with lifetime updates!) that also serves double-duty as a front dash cam. I especially like that it has the posted speed limits always displayed. I have it mounted in the upper left of the windshield out of the way but in a good spot for viewing its small screen.
The rest of the time, it's wireless carplay + siri + google maps on the "big screen".
