Initial operation, Fig. 12
1. Reconnect the battery.
2. Restore complete functioning of the electrical system (clock, trip computer, alarm sys-
tem, airbag, immobiliser, etc.).
3. Switch on the ignition.
4. Insert the map CD in the radio. To register the system and enable map, travel and/or
traffic info, see the operating instructions, Section “C-IQ”, ➽ page 31.
5. Park the vehicle outdoors to ensure unimpeded GPS reception.
6. Switch on the ignition and the radio.
7. Press the NAV button and confirm the user information by pressing the right rotary
control. The main control appears. The navigation radio will now initialize.
After connection of the power supply, the integrated GPS receiver requires approxi-
mately 2 to 10 minutes until GPS reception is satisfactory.
■Setting the mounting angle
In order to ensure perfect functioning of the system, the navigation radio must be set
to the actual mounting angle in the instrument panel.
1. In navigation mode: Select the “Mounting angle” option in the “System settings”
menu.
2. Depending upon the installation, set the angle to between -10 and +30 degrees. The
system does not differentiate between negative and positive angles. Thus, even for a
mounting angle of, e.g. -10 degrees, set a value of “10" in the menu.
■Loudspeaker test
To check the correct connection of the loudspeakers the function “Loudspeaker Test”
in the “INITIALIZATION” menu can be performed. ➽ page 29.
■Setting the clock and the time zone
To ensure that the correct time is always displayed, select the “GPS” option in the
“INITIALISATION” menu under “Clock Settings” and set the time zone for your
location. ➽ page 29.
Checking the vehicle functions
ACheck the safety-relevant vehicle functions only when the car is stationary, or moving
at low speed. Only perform the check in an open area.
Brake system, alarm system, lights, immobiliser, speedometer, trip computer, clock.
■Checking GPS reception
Enter a destination and select “Guidance”. Call up the “GPS / Compass” information
menu via the guidance screen (see operating instructions) and check the number of
satellites. For a sufficiently exact location determination the number should be
between 4 and 8.
■Calibrating the system
For automatic calibration, perform a short test drive (approx. 10 minutes) on digitized
roads. Change direction several times.
