Once you’ve turned your Mileage Tracker on, your trips will automatically generate.
Once the trip has generated (usually about 10 minutes after you’ve stopped driving), it will appear in your To Be Saved section.
Just open your To Be Saved and check the Mileage tab at the top of the screen. From here, you’ll be able to save those trips to your desired folders, or delete any trips you don’t need record of.
