It would be a great upgrade in my view, if , instead of ONLY superchargers , the navigation system listed all chargers, particularly Ecotricity at most motorway stops. My wife's bmw i3 has a complete list in its satnav including car park and ParknRide sites, with distances. this is an IT exercise so no hardware is involved. anybody agree this woul be a benefit? I say this because arriving at Bristol John Lewis SC last week in the small hours, the car park was locked, and I got home with just 9 miles left.
