The 3300 seems to have a French as one of the multi language displays, App mode: "App Mode selected, you can operate the unit's iPod function from your iPod. Also, you can listen to the sound of your iPod/iPhone applications through your car speakers and view any video content on the screen, provided the App supports analogue audio or video output." and that's about it! There might minor other tweaks like bigger SD card and the use of newer iPods.
