vehicle AM and FM antennae along with accompanying text transmissions. These signals are decoded by the module and
played as an audio output or displayed as an information text on the head unit LCD display or the ICM LCD display
depending the system installed.
The HD radio module is located in the LH side of the luggage compartment. The module receives a fused power supply
from the AJB. The module is also connected on the MOST ring and is able to communicate with the other entertainment
and information systems in the vehicle.
CLOCK
The ICM contains the master clock functionality. Other vehicle infotainment modules that require clock functionality use
the time supplied from the ICM.
The clock is available to any control module that is connected to an interconnecting bus, for example, either of the CAN
buses or the MOST ring.
The clock display configurable to show in AM / PM or 24 hour format. Midnight is shown as 12:00AM or 00:00 respectively.
The default condition, if not specified, after power on or delivery, should default to 12:00PM or 00:00. Depending upon the
market set the clock will default to either 12 or 24 hour format.
The time is adjusted from the ICM. Under conditions when any bus could be asleep or shut down, the ICM does not allow
clock adjustments.
