About ecoRoute
The ecoRoute
™
feature calculates the fuel
economy and the fuel price of navigating to a
destination, and offers tools for improving fuel
efciency.
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 specic vehicle and driving
habits, calibrate the fuel economy (page 40).
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.
Go to www.garmin.com/ecoroute for
compatibility and purchasing information.
