I am on an impromptu trip to an unfamiliar area due to a family emergency, and my rental car had no navigation built in. This meant I truly needed to depend on live turn-by-turn GPS navigation in Pure Maps on my Librem 5 for the first time.
It actually worked great! I packed a car vent magnetic mount and I was able to route to various destinations, reroute automatically, and otherwise use it like you'd expect.
