Porsche Communication 
Management (PCM) fRefer to the separate operating instructions 
before putting the PCM into operation. 
fPlease observe the chapter “LOAD SWITCH-
OFF AFTER 2 HOURS OR 7 DAYS” on Page

 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 resul-
ting in serious personal injury or death.
fOperate the components while driving only if 
the traffic situation allows you to do safely.
fCarry out any complicated operating or setting procedures only with the vehicle stationary.The reception conditions for the radio module inte-
grated 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 a qualified specialist workshop.
Accessories which have not been tested and 
approved by Porsche may impair radio reception.
NavigationWhen put into operation for the first time, a 
distance of approx. 31 miles (50 km) must be dri-
ven 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 after 
being switched on before it determines the current 
location. 
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 becomes operational again.
