Management (PCM) fRefer to the separate operating instructions
before putting the PCM into operation.
f Please see the chapter “LOAD SWITCH-OFF
AFTER 2 HOURS OR 7 DAYS” on Page 236.
Warning!
There is a danger of accident if you set or
operate the on-board computer, radio, navi-
gation system, telephone or other equipment
when driving.
This could distract you from the traffic and
cause you to lose control of the vehicle re-
sulting in serious personal injury or death.
f Operate the components while driving only if
the traffic situation allows you to do so safely.
f Carry out any complicated operating or setting procedures only with the vehicle stationary.
The reception conditions for the radio module
integrated in the PCM ch ange 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.
NavigationWhen 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/snow 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 deter-
mine the current locati
on after it has been
switched on.
Serious tire slip (e.g. spinning wheels on snow)
may result in temporaril y inaccurate navigation.
When the battery has been disconnected, it may
take up to 15 minutes before the navigation
system is operational again.
Car Audio Operation/Tips For radio operation see your radio manual
which is included with your on-board litera-
ture.
f Please see the chapter “LOAD SWITCH-OFF AF-
TER 2 HOURS OR 7 DAYS” on Page 236.
FM reception
A vehicle is not an ideal pl ace to listen to a radio.
Because the vehicle moves, reception conditions
are constantly changing.
Buildings, terrain, signal distance and noise from
other vehicles are all working against good recep-
tion.
Some conditions affecting FM may appear to be
problems when they are not.
The following characteristics are completely nor-
mal for a given reception area, and they do not in-
dicate any problem with the radio itself.
Note
Electronic accessories shou ld only be installed by
your authorized Porsche dealer.
Equipment which has not been tested and ap-
proved by Porsche may impair radio reception.
