Using the Tools

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. 

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.
