Acura 3.5 RL, Manual

Page: 1306 / 1453

Muting Logic
Whenever the navigation system is giving guidance,
front speakers are muted. When the voice control sys-
tem is being used, all of the speakers are muted.
When using On-Star, both the audio system and the
navigation system are muted, and the voice control
switch (TALK and BACK buttons) is disabled.
Voice Control Limitations
Before assuming that a voice control complaint is hard-
ware related, ensure that the voice control system is be-
ing operated correctly (see "Voice recognition does not
work", page
23-35) .
LCD Display Unit Limitations
• In cold temperatures, the display may stay dark for the
first 2 or 3 minutes until it warms up.
• When the display is too hot because of direct summer
sunlight, it will remain dark until the temperature
drops.
• When the humidity is high and the interior tempera-
ture is low, the display may appear cloudy. The dis-
play will clear up after some use.
• Fingerprints on the touch panel may sometimes be
noticeable because of the panel's low-reflection coat-
ing. When cleaning the panel, wipe it gently with a
soft cloth. To avoid scratching the panel, do not rub
too hard, or use abrasive cleaners or shop towels.
• The touch panel is an infrared system, so there is no
need to press hard. If a touch switch does not function
immediately, shift your finger slightly, and touch it
again.
Note: Input may be affected by direct sunlight.
Symptom Duplication
• When the symptom can be duplicated, follow the self-
diagnostic procedures and the appropriate trou-
bleshooting procedures.
• When the symptom does not reappear or only reap-
pears intermittently, ask the customer about the condi-
tions when the symptom occured.
-Try to establish if outside interference may have
been the cause.
-Try to duplicate the symptom under the same condi-
tions the customer was experiencing.
-Vibration, temperature extremes, and moisture (dew,
humidity) are factors that are difficult to duplicate.
- Inspect the vehicle for after-market electronic devices
(vehicle locators, amps, radar detectors, etc) that
may be hidden.
Service Precautions
• Before disconnecting the battery, make sure you have
the anti-theft codes for the radio and the navigation
system, and write down the frequencies for the radio's
preset buttons.
• When the battery is disconnected, the internal GPS
clock is reset to "0:00". The clock will reset to the cor-
rect time after the system finishes GPS initialization.
• After reconnecting the battery, you have to wait to get
the initial signal from the satellite, which may take from
10 to 45 minutes. Follow the instructions on the screen.
• After reconnecting the battery, do the power window
control unit resetting procedure.
• Before returning the vehicle to the customer, enter the
radio code, then enter the customer's radio station
presets, and set the clock. Do the engine control mod-
ule (PCM) idle learn procedure.
After Servicing-Map Matching
• Park the vehicle in an area where the GPS satellite sig-
nals will be unobstructed. Make sure the GPS indica-
tor on the map screen is green.
• Drive the vehicle 1 mile before entering a destination
and confirm the road being used is displayed at the
bottom of the screen (map matched).
• Enter the dealer address and confirm the system
routes and performs normally.
• Clear any previous destinations that may have been
entered for testing purposes.
