Overview
There are two audio systems available for the RDX
- The premium audio system is on vehicles without navigation. It includes six speakers, a subwoofer, and an XM receiver.
- The ELS audio system is available on vehicles with navigation. It includes surround sound with nine speakers (the same six that are available on the premium audio system, plus one in each D pillar and in the middle of the front dash), a subwoofer, and AcuraLink® control unit (HIP/XM receiver).
The audio unit acts as the processor for all audio functions. You can select the audio functions from the front panel, the audio remote switch (on the steering wheel), or by using the navigation voice control system. The audio display provides the current front audio status. For vehicles with navigation, additional audio information is available by touching the audio button. (See the Owner's Manual, Navigation System manual for more details.)
Each audio component passes its audio signal to the audio unit. In addition, it communicates with the audio unit via the GA-Net bus. Any open connection in this circuit will cause audio and navigation functions to appear inoperative.
The audio unit has a built-in EEPROM (electrically erasable programmable read-only memory). This memory holds the audio preset data (AM/FM radio frequency, sound settings, etc.) even when the battery is disconnected.
With the ELS and the premium audio system, a stereo amplifier powers the speakers. The 6DVD (6CD) changer output can be directed to the audio unit. The XM radio plays through the audio unit.
A security signal is daisy-chained between the audio and navigation components and integrated into the vehicle's security system.
