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.
