System Diagnosis Mode (cont'd)
GPS Offset Time
This screen is for factory use only. It allows adjustment
of the GPS time. This display updates in real time.
• "GPS Time" is the time as received from the GPS
satellites. It is in Greenwich Mean Time (GMT).
• "System Time" is the internal time used by the navi-
gation unit to calculate your position on the map.
It is also in Greenwich Mean Time (GMT).
• "Display Time" is the time shown on Setup screen 2
"Adjust Time Zone/Clock", and reflects any changes
due to daylight savings time or time adjustments
entered by the customer.
• Date, Hour, Minute, and "Set" buttons should not be
used.
Mic Level
This diagnostic allows you to independently test the
microphone and the TALK and BACK buttons on the
steering wheel (voice control switch). The microphone
and voice control switch are used to activate the voice
control system. The microphone is located near the map
light in the ceiling. It is directional, and works best if the
voice is coming from the drivers seat.
• Press the TALK button on the steering wheel, and in a
normal voice say "testing". The TALK indicator on
the screen should momentarily become green, and
the text "Now Recording..." should appear in yellow.
In addition, the Mic Level indicator should move at
th
least to the 6 bar. If the Talk indicator on the screen
does not briefly become green, then check the wiring
from the steering wheel talk button to the navigation
unit. If there is no "Mic Level" movement when you
speak, then you should check the wire running from
the microphone to the control unit.
• Press the BACK button on the steering wheel. This
should cause the Cancel indicator on the screen to
momentarily become green. If it does not briefly
change to green, then check the wiring from the
steering wheel BACK button to the navigation unit.
