The Pama Eco Navigator Satellite Navigation system might make TomTom devotees think twice. Not only can this GPS give you the most energy-efficient route to drive, it will also provide diagnostics of the car’s performance (such as carbon emissions and MPG) like a little eco-friendly backseat driver.
