use a Tom Tom if I go somewhere when I don’t know where it is which is very rare.
When it’s not being used I take it out of the vehicle and turn it off in the box
I rarely use our garmin and only used it for that trip for kicks and grins to see elevations and ETA’s at way points. I seldom turn my cell phone on and have the gps turned off on it even though “they” can track it with cell tower pings when it is on. I have a ‘12 Ram and who knows what lurks under the dash and in the ECU?
