TestBook/T4 Diagnostics
No serial diagnostic link is provided with the CARiN III navigation system, so TestBook/T4 cannot interact with the
system.

Vehicle Position
If the vehicle’s battery has been disconnected, or if the vehicle has been transported to a new location on another
vehicle (e.g. by trailer or train), the navigation system will require up to 15 minutes to identify the new position. Entering
the vehicle’s position manually, reduces this delay. To enter the vehicle's position manually:

1 Highlight and select Information.
2 From the information menu, scroll down to the next screen and highlight and select Vehicle position.

NOTE: If the correct CD is in the navigation computer, the country is automatically entered. If you have travelled

to a new country, a new CD may be needed.

3 From the vehicle position menu, highlight and select City, then use the typewriter menu to enter the vehicle’s

position (town, road, etc.) in the same way that you would enter a destination.

4 Once the town and road names are entered, the navigation computer asks for a junction. This is the name of the

road that forms the next junction ahead of the vehicle.

5 Highlight and select Junction, then enter the name using the typewriter, or select the correct road name if a list

of names is displayed. Crossing the junction will be highlighted. Drive the vehicle in the direction of the junction
and press the rotary controller when you reach the junction.

NOTE: The vehicle position menu provides a street map facility which enables you to check your vehicle’s current

position and assists in identifying the name of the next road junction.

Provided that the information entered into the computer is correct, the navigation system requires approximately 1
minute to determine the vehicle's position.

Navigation and Trafficmaster
Road navigation and off-road navigation are accessed from the main menu by highlighting and selecting the
appropriate title with the rotary controller. In both modes of navigation, this brings up a safety notice on the display
unit. Pushing the rotary controller again accepts the safety notice and replaces it with a menu screen, which is the
entry point for operation of the navigation function. The Trafficmaster function only operates in the road navigation
mode, and is activated and de-activated by pushing and holding the menu switch for more than 0.5 second. When
activating the Trafficmaster function, the system returns to the navigation mode if the menu switch is not released
within 1.5 seconds.

Refer to the Owner Handbook: Navigation, CARiN III & Traffic Master, Publication Part No. LRL 0586ENG for full
details of how to operate the road navigation, off-road navigation and Trafficmaster functions.
