Operation, Safety
Porsche Communication 
Management (PCM) fRefer to the separate operating instructions 
before putting the PCM into operation.
fPlease see the chapter “LOAD SWITCH-OFF 
AFTER 2 HOURS OR 7 DAYS” on Page 258.
 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.
fOperate the components while driving only if 
the traffic situation allows you to do so safely.
fCarry 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.
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 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.
Car Audio Operation/Tips For radio operation see your radio manual 
which is included with your on-board litera-
ture.
fPlease see the chapter “LOAD SWITCH-OFF AF-
TER 2 HOURS OR 7 DAYS” on Page 258.
FM reception 
A vehicle is not an ideal place 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 should only be installed by 
your authorized Porsche dealer.
Equipment which has not been tested and ap-
proved by Porsche may impair radio reception.
