About ecoRoute 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, unless you are using the ecoRoute HD accessory. To receive more-accurate fuel reports for your specific vehicle and driving habits, calibrate the fuel economy (page 36). In some areas, an ecoRoute HD accessory is required to use ecoRoute features. ecoRoute HD Accessory When connected to the ecoRoute HD accessory, your device can receive real-time vehicle information, such as error messages, RPM, and battery voltage. Your device includes data read from the vehicle by the ecoRoute HD accessory when calculating ecoRoute data.
