Audio System
There are three radio systems available that communicate on the PCI bus. They are RBR, RBN, and RAZ models. They use the bus for two reasons. First is to communicate trouble codes to the
body control module, the second is for use with the driver memory selection system. The radio stores two sets of station presets and can be recalled by pressing the optional memory select button (located on the drivers door). The RBR will have 6 speakers and a 120 watt external amplifier. The RBN will have 7 speakers and a 240 watt external amplifier. The RAZ will have 9 speakers and a 320 watt external amplifier. Depending on the manufacturer, some systems have a Front/Rear channel system and others have a Left/Right channel system.
