I've got an ATOTO A6, does most of what I want it to, need to tether to a phone to make best use of it, but it has google maps for navigation, poweramp for music, apps like victron connect, torque, and it has inputs for front/rear dash cam and reversing cam. Hands free phone built in. DAB is poor with the VW aerials in the wing mirrors but a screen mount aerial might be better.
It can be difficult to operate (ie change tracks) as the on screen buttons are small and the head unit is offset in the centre but it will work with steering wheel controls if you get the right adapter.
