Calibration: Each rally will provide a calibration section to allow you to compare your odometer to the one used to measure the rally.
Before you start, use the Rabbit menu to go to Connections. Be sure your Odometer Source GPS is set to MPH (Imperial).
Advanced Calibration Features: When on the Calibration display you will see three dots in the upper right corner. Press them and the Calibration History screen appears. This shows history. You can rename them to match a rally. If you press on one of the Calibration boxes you get another menu.
Current Menu - Allows you to manually set the factor for each of the sources.
CAL date & time - Selecting one of the other these allows to switch to that calibration, rename it, or delete it.
Original- Shows the calibration that the app started with.
