Trust me, I've tried turning off tracking. If I do a hike with tracking on it works perfect of course, then I'm done hiking I turn off tracking, turn off the unit, drive home. Even with tracking off, the moment I turn on the unit and move more than 5ft the odometer and trip data instantly jump up adding the miles the unit was moved from A to B while off. It doesn't matter that the tracking was turned off or not. This is a big deal to me as I like to keep a running tally of how far I hike each year.
