I Have Dynaudio, and Nav pro. Couldn't tell you the difference over standard it was on the car when I bought it. Voice command is pretty Good. Gesture control is rubbish. Sat Nav works perfectly for the odd time it's used, Pro screen is set up on the Radio Stations, and the Nav on in the Virtual Cockpit, Which is pretty cool. I probably wouldn't add it on the options. But if as I did, found a car with it on. It would be a no brainer.
Dynaudio, is the first option, Every R owner should Get,
