Works amazingly well. Never had a problem with it in the last 4 years or so.
bought it online and had it installed professionally.

Works very well. The user interface is a bit confusing (seems like Apple has spoiled me?.) The main problem is that the remote control does not have a "menu" key, which is only accessible through the unit itself. This is puzzling, since other, less commonly used buttons (such as the "sound" button) are available on the remote.
Also, quite expensive - was expecting to pay about 20% less than I did, but in the end I do not regret it.
Great sound and lots of features
Some issues with how it's designed, not very useful remote, expensive.
