Prerequisites For The Mobile Phone; Hands-Free Quality; Interruptions To The Connection While Driving - Porsche PCM3.1 Operating Manual

– In the case of a PCM with PCM telephone,
connection takes place using the SIM Access
Profile if this profile is supported by the mo-
bile phone used. When connecting using the
SIM Access Profile, the SIM card of the mobile
phone is used for operation of the PCM tele-
phone. The data on the SIM card (phonebook
entries and text messages) is read out by the
PCM and is available for use on the PCM.
The range of functions for a connection using
the SIM Access Profile is largely the same as
the function of the PCM telephone with SIM
card inserted.
If the mobile phone does not support the SIM
Access Profile, connection takes place using
the Hands-Free Profile.
With mobile phones that support both profiles,
it is possible to switch between the connection
types.

The option of connection using the SIM
Access Profile is not available on all mobile
phones and must also be activated on the de-
vice for some mobile phones.
In some countries there may be limitations on
®
the use of devices with Bluetooth . Please
contact the local authorities for further infor-
mation.
