The Garmin ecoRoute GPS is a pretty full featured fuel mileage calculator where you input your vehicle’s fuel mileage (city/highway), type of fuel (unleaded/diesel/etc), price and other parameters. The fuel price can either be manually entered or downloaded via MSN Direct’s fuel prices. If you’re using the MSN data, merely the price of the lowest grade fuel is used. If you use mid-grade or premium fuel you’ll need to enter those fuel prices manually. One of the trip computer’s data fields (bottom left which formerly displayed Total Time) has now been changed to show Overall Fuel Cost.
Other features of the Garmin ecoRoute GPS include a Driving Challenge game where you try and get as close to a score of 100 points which are calculated using various parameters of the way you drive like acceleration, deceleration, & speed.
