Calibrating The Fuel Economy; Viewing The Fuel Report - Garmin Nuvi 1690 Owner's Manual

The data provided by the ecoRoute
features are estimates only. The
data is not actually read from your
vehicle. To receive more-accurate
fuel reports for your specific vehicle
and driving habits, calibrate the fuel
economy.
The first time you access the
ecoRoute features you will be asked
to enter fuel and mileage information
about your vehicle.

Viewing the Fuel Report

If you have entered your vehicle
profile and the current fuel price,
your nüvi calculates the average
fuel economy for your vehicle, your
carbon footprint, and the cost of the
fuel consumed.
The fuel consumption data is
based on estimates for speed and
acceleration for an average vehicle.
