I DID CALIBRATE WITH A MEASURED "ONE MILE", I'M JUST NOT SURE OF THE ACCURACY OF THE TRIP ODOMETER BECAUSE I HAVE HAVE TO USE IT FOR WHEN I HAVE TO REFUEL
Can you check the odometer against another measured mile. Most report this speedometer to be very accurate. Call Dakota in the morning if you are unsure of it's operation. They will be happy to answer any questions. 1-800-593-4160
