In some areas, before you can use ecoRoute™ features, you must purchase an unlock code. Go to www.garmin.com/ecoroute for more information.

The ecoRoute feature calculates the fuel economy and the fuel price of navigating to a destination, and offers tools for improving fuel efficiency. The data provided by the ecoRoute feature is an estimate only. The data is not actually read from the vehicle.

To receive more-accurate fuel reports for your specific vehicle and driving habits, you can calibrate the fuel economy (Calibrating the Fuel Economy).
