Most people want to add more excitement to long drives with family or friends, instead of feeling like they are just moving from one place to the next. But not all of the passengers want to listen to the same music. However, if each of the passengers could enjoy their favourite contents throughout the trip, the entire driving scene would be much more pleasurable. By separating the interior of the car into the front seat space and back seat space, and by using a 2-Zone system that can play back separate audio or visual sources independently from each other, it is possible to create an entirely new in-car environment that until now has only been a dream. So while the front seat passengers are listening to their favourite CD or watching a DVD, the back seat passengers can be absorbed in a video game, making it possible to create two completely different audio-visual areas within the same car. Starting with its 2-Zone system that embodies the concept of rear entertainment, Clarion has a lineup of products that respond to the widest variety of user needs, including an overhead monitor perfect for mini-vans, or compact monitor models for the headrests.
