Navigation/Radio System Glovebox-Mounted CD Changer With the CD changer, you can play up to six CDs continuously. Normal size CDs may be played using the trays supplied in the magazine. The smaller CDs (8 cm) can be played only with specially designed trays. Navigation/Radio Display and Controls Your vehicle may be equipped with an AM-FM radio navigation system that includes digital signal processing (DSP), a radio data system (RDS) with program "type" selections (PTY) that will seek out the kind of music you want to listen to. The radio system can also communicate with your navigation system to broadcast announcements on traffic, weather, and emergency alert communications. For information on how to use this system, see the "Navigation System" manual. You must first load the magazine with CDs before you can play a CD. Each of the six trays holds one CD. Load the trays from bottom to top, placing a CD in the tray label side up. If you load a CD label side down, the CD will not play and an error will occur. Repeat this procedure for loading up to 6 CDs in the magazine. 3-101
