The RB4 is CD-based and utilizes two discs for the U.S. This is supplemented by the voice guidance system (English, Spanish, and French). Text information such as distance, ETA, current/next street names, and complete route list is also available. Pictograms for traffic circles and every conceivable type of maneuver are displayed. The main difference when compared to the premium model RB1 is that the RB4 provides similar features but without a MAP.
