GARMIN GPS Nüvi 1390T

EcoRoute calculates a more fuel-efficient route, meaning you can make some great savings. It also gives you an overview of how many miles you cover, how much petrol you consume and just how much carbon dioxide your vehicle releases back into the atmosphere. Readings can be taken on a monthly or annual basis.  

The nüvi 1390-T boasts a Text-to-Speech mode and Junction View for help at upcoming turns. Its 4.3-inch screen makes it easy to read directions, while the sound and visual alerts tell you when you're going too fast and warn you when there's a speed camera ahead.  

Garmin's nüvi 1390T is even supplied with a TMC receiver, and it's ideal for use in and out of the car.
