Section 522 (Audio/Video/Entertainment/Connectivity (Service Information)): Description: Description

WARNING: This page is about a different car, the 2016 Dodge Charger and 2015 Dodge Charger. However, it is still accessible from the selected car via links, so may be relevant.

Several combinations of radio receivers and speaker configurations are offered. The audio system operates on a non-switched fused B+ battery current source and is turned On or Off by electronic messages received over the Controller Area Network (CAN) data bus so that the system will only operate when the status of the ignition switch is Run or Accessory.

The radios can be identified by sales code RA2, RA3 and RA4. An optional navigation feature is also available in the RA3 radio for this vehicle. Navigation is standard in the RA4 radio for this vehicle. Refer to DESCRIPTION .

The RA2, RA3 and RA4 radios all have an internal Hands Free Module (HFM). There is no external HFM because all hands free functions are integrated into the Radio Receiver Module (RRM) (also known as the radio or the head unit).

The audio system includes the following components:

Antenna - The base radio antenna is integrated into the back glass and includes an electronic antenna module located on the header above the back glass opening and concealed above the headliner. The base antenna is capable of receiving AM and FM signals. An optional body color, multifunction (satellite audio, GPS and cellular) antenna (also known as the shark fin style antenna) is located at the rear and center of the outer roof panel.
Power Amplifier - One of three optional audio power amplifiers are available with certain premium audio systems only. Either amplifier is located on the instrument panel support structure under the driver side end of the instrument panel. Refer to AMPLIFIER, DESCRIPTION .
Radio Noise Suppression Components - Devices designed to suppress Radio Frequency Interference (RFI) and ElectroMagnetic Interference (EMI) radio noise are used in this vehicle. Refer to COMPONENTS, RADIO NOISE SUPPRESSION, DESCRIPTION .
Radio Receiver Module - Several optional Radio Receiver Modules (RRM) (also known as the radio or the head unit) are available for this vehicle. Refer to RADIO, DESCRIPTION .
Remote Radio Switches - Optional remote radio switches located on the steering wheel are available in this vehicle. Refer to SWITCH, REMOTE RADIO, OPERATION .
Speakers - Several optional speaker packages are offered in this vehicle. Refer to SPEAKER, DESCRIPTION .
Media Hub - A media hub including a Secure Data (SD) card slot, a Universal Serial Bus (USB) port and an auxiliary cable input jack located within the storage bin of the center floor console is optional equipment. Refer to MEDIA HUB, DESCRIPTION .

Certain functions and features of the audio system rely upon resources shared with other electronic modules in the vehicle over the CAN data bus network. The RRM contains a microcontroller and programming that allows it to communicate with other electronic modules in the vehicle over the Controller Area Network - Interior High Speed (CAN-IHS) data bus. The RRM can also receive electronic message inputs over the CAN-C data bus; however, the RRM is not a CAN gateway. All of the RRM electronic message outputs are through the CAN-IHS data bus. Refer to COMMUNICATION, DESCRIPTION .

Many of the audio system components cannot be adjusted or repaired. If they become damaged or ineffective, that component must be replaced. Those that can be repaired must be serviced by an authorized electronic warranty repair station. Refer to the appropriate warranty policies and procedures information.
