I thought about getting a traditional navigator to avoid even relying on phone navigation.
Well, of course all the Garmins and Tomtoms available now have "built-in wifi for updates" and often BT for phone notifications too. Sure, I could just not configure either but what if I want a navigator _without any radios_ and with controlled updates via SD card.
Maybe a dedicated Android phone in the car with offline OpenStreetMaps installed and airplane mode on is more realistic. Or some old 2nd hand navi that's still updateable.
I use an older Garmin, purchased from ebay. Works fine, updated maps via a laptop recently. Needed an extra SD cards for space.
