Nearly every GPS receiver has a trip computer. This one allows you to reset each piece of data separately, or all at once. If you're driving, it also displays the current speed, which is handy if you haven't corrected the speedometer on your lifted 4x4. Part of the ecoRoute feature of this Garmin, we found the fuel cost estimator to be very accurate. It lets you input your vehicle data and fine-tune it, and enter the current price of fuel.
