So I asked the dealership to show me the new AVN. Compared it with the current. So here's my conclusion.
The current, aesthetically, is 10/10. The new aesthetically is 6.5/10.
The current has limited features. The new is a full fledged android tablet. Lots of flexibility. Car tracking capabilities, geofencing etc.
The current's build quality is OEM quality. Top notch.
The new's build quality seemed to be good. The screen was very responsive. Smooth.
