GPSM
The GPS antenna integral to the GPSM is used to acquire the compass heading. The compass heading is sent over the CAN to be displayed on the FCDIM.
The GPSM provides vehicle location information for identifying the vehicle location in the event of a collision.
The GPSM requires PMI when it is replaced.
Noise Suppression Equipment
The radio frequency suppression equipment reduces interference transmitted through the speakers by the engine, ignition, and electrical systems. When installing any new radio suppression equipment components, make sure that a good contact is made at all connections.
Steering Wheel Switches
The RH upper and lower steering wheel switches contain series of resistors. Each steering wheel switch function corresponds with a specific resistance value within the switch.
The SCCM sends a 5-volt reference voltage to the RH upper and lower steering wheel switches on the input circuit. When a switch is pressed, the voltage is routed through the corresponding resistor(s), through the return circuit, and then to ground through the SCCM. The SCCM monitors the resultant voltage drop to determine which switch was pressed. The voltage drop varies depending upon the resistance of the specific switch pressed.
The steering wheel switch inputs are sent as network messages from the FCDIM to the APIM to control SYNC® functions, or to the ACM to control audio functions.
The RH upper steering wheel switch inputs are sent as network messages from the SCCM to the ACM to control audio functions.
The RH lower steering wheel switch inputs are sent as network messages from the SCCM to the APIM to control SYNC® functions, or to the ACM to control audio functions.
SYNC® Microphone
The SYNC® microphone is powered by the APIM.
The SYNC® microphone receives SYNC® system voice commands and outgoing audio during a phone call. The monitored sounds are converted into analog signals by the microphone and sent to the APIM as fluctuating AC voltage.
USB Ports/Cables
Data is sent from the front USB port ( USB1) to the APIM ( USB cable with black end) through the front USB cable. Data is sent from the rear USB port ( USB2) to the APIM ( USB cable with grey end) through the rear USB cable.
The USB ports are part of the USB cables, and cannot be replaced separately.
The USB ports are powered through the USB cables by the APIM and can be used to power and/or charge a device if the device supports this feature. If the device does not support this feature, an external power source is needed in order to power the device.
