Component Description

Voice recognition allows certain phone and audio system functions to be controlled with voice commands to reduce or eliminate the need to interact with the FCIM, FCDIM, and/or device while driving.

When the voice steering wheel switch is pressed, an audible prompt originating from the APIM is heard from the speakers. Based on the customer’s setting, audible prompts will either be a voice or a simple tone. When interaction mode is set to standard, detailed voice guidance is provided. When interaction mode is set to advanced, most prompts are tones only, and minimal voice guidance is provided. The microphone receives the voice commands and sends them to the APIM. For more information, refer to “voice recognition” in the Owner's Literature.

Component Description

ACM

The ACM can be operated with the ignition in RUN, ACC, or OFF.

The ACM receives radio waves containing audio from the antenna coaxial cable(s)s and converts them into fluctuating AC voltage. The ACM receives stereo and mono audio signals from the APIM in the form of fluctuating AC voltage. The ACM processes all inputs, and depending on the input received, sends stereo or mono analog audio signals to the speakers as fluctuating AC voltage.

The ACM contains the CD player.

The ACM contains the DACMC for vehicles with the 2.3L or 5.2L.

The ACM and DACMC require separate PMI procedures when the ACM is replaced.

AM/ FM Antenna Amplifier - Coupe

The AM/ FM antenna amplifier receives AM/ FM radio waves from the on-glass antenna grid. The AM/ FM antenna amplifier is powered by the ACM and amplifies AM audio signals to improve reception. The AM/ FM radio waves are sent through the AM/ FM antenna coaxial cable to the ACM.

ANC Microphones - 2.3L

For a coupe, two ANC microphones (overhead console-mounted and center rear headliner-mounted) measure the amplitude and phase of the engine noise inside the passenger compartment. For a convertible, three ANC microphones (overhead console-mounted, RHR quarter panel, and LHR quarter panel) measure the amplitude and phase of the engine noise inside the passenger compartment. The monitored sounds are converted into analog signals by the microphones and sent to the DACMC (contained within the ACM).

Antenna

The AM/ FM radio uses the on-glass (coupe) AM/ FM antenna grid or fender-mounted (convertible) AM/ FM antenna to receive analog radio waves. The radio waves are sent through the AM/ FM antenna amplifier (coupe) or amplifier integrated into the antenna base (convertible) and AM/ FM antenna coaxial cable to the ACM, where they are further amplified.

To compensate for AM signal strength loss as the radio waves are transmitted from the antenna to the ACM, battery voltage is applied to the antenna to boost the AM radio signal. This allows the AM radio waves entering the ACM to be approximately the same strength as they were before amplification at the antenna.

APIM

The APIM can be operated with the ignition in RUN, ACC, or OFF.

The APIM receives stereo and mono inputs. Stereo inputs include audio from the USB ports, audio input jack, connected Bluetooth media device, and outside device during a phone call. The mono input includes signals from the SYNC® microphone.

Stereo outputs include audio from the USB ports, audio input jack, and connected Bluetooth-enabled media device. Mono outputs include audio from the TTS feature, incoming call ringtone, ringback tone, outside device during a phone call, voice or tone prompts initiated from the voice steering wheel switch and FCIM, and SYNC® system instructions.

The TTS feature allows the customer to hear information through the audio system speakers so it does not have
