It's a decent system but it's undone in my '09 OB Ltd. by a few factors, including (1) road noise at highway speeds is overbearing and you have to really crank the system to hear it well; in contrast to my former Audi A6 with much better NVH suppression, the cabin at speed was a better "listening room"; (2) the door panels are such flimsy plastic that they resonate and rattle when the system is played at any real volume, again a poor contrast to the former Audi.
This, of course, is comparing a $28-30k car to a $40k+ car, so not quite apples to apples, but those are my experiences ...

I don't miss the Audi repair/reliability issues.
