[6] Frequently asked questions about transferring of
phone book entries and call lists – Bluetooth
®
Phone Book Access Profile (PBAP)
Can I access the phone book contacts and call lists
stored on my mobile phone from the CDR-31/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. Some models, for example, do not
transfer phone book contacts stored on the SIM card to
the PCM, and in some cases no access is possible to
phone book contacts stored on the phone itself. Other
phones may transfer this information but provide only
one phone number per name.
Another possibility is that the user must confirm the
PCM’s request by pressing a key on the telephone. If
this confirmation is not provided, neither phone book
contacts nor call lists are transferred. This confirmation
must be repeated each time the ignition is switched on.
You can avoid it, however, by authorising the CDR-31/
PCM in the mobile phone’s device list. This device list is
found under the Bluetooth
®
settings on most phones.
Please note that some mobile phones with the Android
®
operating system may display the request for authorisa-
tion to transfer the phone book and call lists simply in
the form of an icon in the header on the phone screen.
In this case, touch the icon and drag it down on the
touchscreen to enable you to confirm the request.
Are there differences between the CDR-31 and PCM
with respect to transferring phone book contacts and
call lists?
Yes. The CDR-31 transfers only phone book contacts and
call lists from the memory of the mobile phone itself,
while the PCM transfers data from both the phone’s
memory and its SIM card. However, transmission 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 the
PCM depends on your individual mobile phone. Please
note the following points:
1. The PCM only shows entries containing at least one
telephone number.
2. The maximum number of phone numbers shown in
your car is limited to 2,500 in cars with PCM. In the
CDR-31, the maximum number of phone book entries
depends on the Bluetooth
®
profiles supported by the
phone. If the phone supports automatic download
via the Phone Book Access Profile, a maximum of
600 entries can be loaded into the CDR-31 phone
book. If this profile is not supported, the phone book
entries must be transferred manually. A maximum of
100 entries can then be stored.
3. Some mobile phones sort the phone book entries as
‘first name, last name’, and some as ‘last name, first
name’. As a result, the phone book listing in your
PSM may differ from that in your mobile phone. You
can change this by going to ‘PHONE/OPTION/SET
PHONE/Phone book Settings/Sort’, which will often
solve the problem.
4. Some types of phone only transfer one number per
name. In these cases, information about the type of
number is frequently also missing.
5. Some mobile phones also have problems in transfer-
ring data when special characters are used.
6. Some entries may be duplicated if they are stored on
both the SIM card and the phone itself (the phone
books of many mobile phones do not show SIM
cards). In this case you can hide the SIM card entries
by selecting ‘PHONE/OPTION/SET PHONE/Phone
book Settings/Phone book Memory’.
7. The phone book in the PCM may be empty if your
mobile phone has confirmed a data transfer without
sending any data. To repeat the phone book transfer
process, select the function ‘PHONE/OPTION/SET
PHONE/Phone book Settings/Transfer phone book’.
8. Linked contacts are displayed as a single instance
on the phone but multiple instances are sent to the
PCM. As the PCM does not support linked contacts,
it displays each instance separately.
