2005-08 ACCESSORIES AND EQUIPMENT Navigation System - RL
control system is being used.
Solar Angle
The navigation system uses the sun's angle, along with the sunlight sensor to control the driver/passenger
A/C airflow.
Off Road Tracking (breadcrumbs)
Off road tracking dots that can be followed on the map to retrace your route back to a mapped (digitized)
road.
Clock and Time Zone
The clock set up allows you to set daylight setting time, auto time zone and time adjustment.
Muting Signal Logic
The audio muting logic is controlled by the audio unit. The audio unit determines what audio source has
priority to use the speakers.
The priority of the audio sources is as follows:
On-Star ('05-06 models) has the highest priority, followed by HFL, AcuraLink, navigation, and finally the
radio/CD-DVD player. The priority is passed by On-Star ('05-06 models), HFL, and AcuraLink to the audio
unit by dedicated mute wires. The navigation mute signal is passed to the audio unit on the GA-Net bus.
The navigation unit temporarily disables the voice control buttons, but allows guidance to be heard. In
addition, the audio unit suppresses the output from the radio, XM unit, disc player, or other audio
accessories.
When the navigation system sends out a voice route guidance command, the audio front center speaker is
muted, and the navigation voice is heard in the front speakers.
When the navigation voice control system is in use, all of the speakers are muted, and the navigation voice
prompts are heard from the front speakers.

Map Database

Audio Unit
The audio unit receives the voice guidance instructions from the navigation unit, and transmits the
instructions through the front speakers even when the audio system is in use.
