Does anyone know why the Dynaudio Sound upgrade was discontinued on new Tiguans?

This is despite the Golf range having this option available. It limits any sound upgrades for those that value their music on an otherwise great car.

VWA really does make some strange decisions!

I would appreciate it if they offered a "Premium Package" like they do in some overseas markets, bundling together for instance: Sat-Nav, Reversing Camera, Dynaudio and Bi-Xenons. One can only hope...
