Are you saying every tomtom, garmin, etc used Bluetooth and cell services for navigation all those years?
Not to be argumentative but dedicated GPS devices didn’t always have that option. Also I’m curious: it uses triangulation off cell towers to help. I don’t see how Bluetooth helps improve accuracy. Do they map WiFi spots accurately?
