A six disc CD changer is used together with the RTI control module on the older RTI system.

This unit only handles CD discs with map information, not music CDs.

The discs contain information about road networks, streets, voice guiding and the software required for the system to function. The CD changer communicates with the RTI unit on serial buses (Melbus).
