Is there a way to watch DVD/Video on the IS350 Navigation System? And since the IS can play mp3s, would it be possible to play mp3s that's on a DVD disc in the player?

 

You can start by looking at the FAQ section.

 

You can watch DVDs only if you have the Mark Levinson System with Navigation.

It's a special package. If you order both but separate instead of the combined package, you have surround sound quality premium audio and the nav system, but no DVD player.
