FAQ
Questions about transferring data.
Can I access the phone book contacts and
call lists stored on my mobile phone from
CDR/PCM?
Access to the phone book contacts and call
lists of a mobile phone is dependent on the
range of functions offered by the phone. With
some devices, for example, it is not possible
to access phone book contacts stored on
the phone itself. Others may transfer this
information but provide only one phone
number per name. Another possibility is
that the user must confirm PCM’s request
by pressing a button on the phone. If this
confirmation is not provided, neither the
phone book nor call lists will be transferred.
Are there differences between CDR and PCM
with respect to transferring phone book
contacts and call lists?
Yes. CDR transfers only phone book contacts and
call lists from the memory of the mobile phone
itself, while PCM transfers data from both the
phone’s memory and its SIM card. However, the
transfer of phone data is always dependent on
the type of phone.
Why is my phone book not displayed correctly
in my car?
Transfer and display of your phone book contacts
by PCM depends on your individual mobile phone.
Please note the following points:
PCM only shows entries containing at least one
telephone number.
The maximum number of phone numbers shown
in cars with PCM is limited to 2,500. In CDR,
the maximum number of phone book entries
depends on the Bluetooth
®
profiles supported
by the phone.
Some mobile phones sort the phone book
contacts as ‘first name, last name’, and some
as ‘last name, first name‘. As a result, the
phone book listing in your PCM may differ from
that in your mobile phone.
Some phone models transfer only one number
per name. In this case, information about the
type of number is often also missing.
Some mobile phones also have problems in
transferring data when special characters
are used.
Some entries may be duplicated if they
are stored on both the SIM card and the
phone itself.
The phone book in PCM may be empty if
your mobile phone has confirmed a data
transfer without sending any data.
Linked contacts are displayed as a
single instance on the phone but multiple
instances are sent to PCM. As PCM does
not support linked contacts, it displays
each instance separately.
There is a detailed functional overview of mobile phone models that have been compatibility-tested by Porsche, starting on page 43. An explanation of the terms used here can be found in the glossary starting on page 38.
