I have this unit, here's a quick review.
The built in Garmin navigation does display on the DIS, not quite as well as the VW RNS510 though. Air Con, Steering wheel controls, heated seats and parking sensors display on screen, though not flawlessly, the unit needs you to 'Agree' to terms every time it switches on from cold so you can't see the parking sensor display until you've pressed it.
The unit is as expected, it has all the bells and whistles but not quite the class of the VW RNS510 and is much harder to use, I'm fairly techy and some of the Garmin functions I had to read the manual for, just not thought out that well. The whole user interface is flashy and quite American. The unit responds quickly to touch and no problems with the touch screen usage.
Will post a full review soon but initial thoughts are, if you want a factory fit then its easily the most advanced option available, it has CarPlay, Android, Sat Nav, Bluetooth Calling, USB / HDMI input. DAB+, Spotify built in (unlike CarPlay this works wirelessly) Camera inputs, Dual Zone audio and much more.
If you're not fussed about the Factory fit, then you might want to consider an standard aftermarket unit, as there's plenty of ones available for under the price of this, for example the Pioneer F88DAB, although this is now a pretty old unit and the CANBUS unit has to be brought separately (£130) and a fitting kit too (£35) so that adds up.
Any questions let me know.
