I think that's a standard feature and is more inclined to kick in with the car in D for some reason
Seems unlikely that the screen comes standard (based on the Belgium option list that is).
Most likely it's a bonus feature when you indeed get the Satnav that the screen changes the moment you switch to D.
I've seen this during the event where my dealer showed the Giulietta.
When you switched to D or N or A it showed you what features were enable or set to what mode, along with the turbo boost and "power" bard (which is actually just a link to the throttle pedal, but still awesome )
the climate controls have evolved from the 147 dials.They are bigger, but without the rubber grippy insert and the display window is in the middle instead of that quaint eliptical wimdow above the control knob.
I sat in a Nissan GTR going around a track once and I couldn't help staring at all the info on the screen - turbo boost, engine temp, diff temp, traction split, lap time... it's all eye candy for the passenger, there's no way for the driver to absorb all that and still drive straight. I'll stick to the plain and simple boost gauge on the Mito
Its an expensive G meter! I think I would prefer the Tomtom option. The cost is around £65 to have the socket in the dash, then a few hundred for the tomtom itself. You then have no suction cups or dangling wires, and I am assuming you will be able to control music etc.. on the tomtom screen (you can on the tomtom system in the Fiat 500)
