I'm considering buying this unit. One of my needs is to access MP3 on a music server and be able to view and select songs via the touch screen. Has anybody done this, if so how is this connected and how functional is the software in this area? It would be great if you could simply access something like MS media Player. How does it connect to your audio system to play the music? I didn't see anything one their website for this.

Thanks for any help you can provide
