A friend has this wifi hotspot tech in his Audi A8, sounds great on paper, but he doesn't use it as it's always dropping the connection. Personally if you want a wifi hotspot, get a 'myfi' device, that way you have it even out of the car.
...........Same as rear screens, compared to a couple of iPads/minis, holders and Bluetooth headphones which are a far cheaper and better alternative IMO. ON THE WAY: BMW F21 M140i
MERCEDES GL350 - Metallic Navy Blue w/Grey interior

GOING: BMW F31 335D MSport+ xDrive Touring
GONE: Land Rover Discovery 4 HSE - Stornaway Grey w/Black Interior (wish we'd kept it )
GONE: BMW F10 520D MSport - Carbon Black
GONE:MY12 RRS SDV6 HSE Sumatra/Ivory/Grand Black Privacy glass

The wifi is really a by-product of the other things though Mike
