Navigation System

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

least to the 6th 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.ProCarManuals.com

VSP Count

This screen displays the number of pulses per revolu-

tion of the tire. This is for factory use only, and should

not be changed.

• "Pulse Count Setting" should always be set to

"Auto"

• "VSP Count" should always be "4", and should never

be adjusted or set to any other value.
Demonstration

This screen is for factory use only, and should always be

set to "OFF". Occasionally this setting is turned "ON"

when vehicles are being used at Auto Shows or similar

events. Turning this feature on, allows the navigation

system to automatically follow a route to a destination

when the vehicle is stationary.

Version

This screen displays the current version of the program,

and allows the loading of a new version of the program

either from a CD/DVD or from a PC card.

The D-Ram Program version should always be greater

than or equal to the Disc Program version. The mapped

database version is the date of the database on the DVD.

The Model code is 23H, and is for factory use only.

Do not use either of the load buttons, unless instructed

to do so by the factory.ProCarManuals.com
