Porsche Communication Management (Pcm) - Porsche 911 Carrera Owner's Manual

Porsche Communication
Management (PCM)
General information regarding the
Porsche Communication Management
Refer to the separate operating instructions
before putting the PCM into operation.
Please observe the chapter "LOAD SWITCH-
OFF AFTER 2 HOURS OR 7 DAYS" on page
293.
Warning!
There is danger of accident if you set or
operate the on-board computer, radio,
navigation system, telephone or other
equipment when driving. This could distract
you from trafc and cause you to lose control
of the vehicle resulting in serious personal
injury or death.
Operate the components while driving only if
the traffic situation allows you to do so safely.
Carry out any complicated operating or setting
procedures only with the vehicle stationary.
The reception conditions for the radio module
integrated in the PCM change continuously as
you drive. Interference from buildings, terrain and
the weather is unavoidable. FM stereo reception
is particularly susceptible to varying reception
conditions.
Electronic accessories should only be retrofitted
by your authorized Porsche dealer.
Accessories which have not been tested and
approved by Porsche may impair radio function
and reception.
Navigation
When put into operation for the first time, a
distance of approx. 30 miles (50 km) must be
driven in order for the navigation system to
complete the process of fine calibration. The
same applies when the tires are changed (e.g.
summer/winter tires) or new tires fitted. Full
location accuracy is not yet achieved during the
fine-calibration process.
If the vehicle has been transported (e.g. ferry,
car train), the system may take a few minutes to
determine the current location after it has been
switched on.
Serious tire slip (e.g. spinning wheels on snow)
may result in temporarily inaccurate navigation.
When the battery has been disconnected, it may
take up to 15 minutes before the navigation system
is operational again.
