5. Frequently asked questions (FAQs)
What can I do if I can't pair or connect my mobile
phone despite the Bluetooth
being enabled?
There are several possible causes:
1. On some telephone models, each connection request
by the car must be confirmed by pressing a button. If
this confirmation is not provided, the connection will
not be established. This confirmation request each
time the ignition is switched on can be avoided by
authorising the PCM in the mobile phone's device list.
This device list is found under the Bluetooth
on most phones.
2. There are situations where the mobile phone will not
allow a connection because of an erratic condition.
Often, the only way to correct this condition is to
switch the phone off and on again or to briefly remove
the battery.
3. It can happen that a mobile phone does not appear
in the PCM's search list due to unfavourable external
conditions. In this case, you can also start the pairing
process from the mobile phone. Make sure that the
Bluetooth function is enabled on the phone and on
®
the PCM. Also ensure that the PCM is in the Bluetooth
device list, since the mobile phone will be able to
'see' it there. In addition, the corresponding menu
item (PCM visible) must be activated, in Bluetooth
Settings under PHONE/OPTION/SET PHONE'.

4. It can happen in very rare cases that the pairing
information is lost on one or the other side, which
means the devices cannot establish a connection.
In this case, delete the entry left on the phone or in
the car and repeat the pairing process.
5. Some phone models allow the user to mark the
Bluetooth profiles supported. Here too, any loss of
®
profile markings may prevent a connection from being
established.
6. Bluetooth connection problems linked to AUX BT may
®
be caused by parallel operation or the connection
sequence of the telephone and audio profiles. In this
case it may be useful to deactivate the AUX BT
function by going to DISC-OPTION-SET DISC/AUX to
ensure all phone functions are stable and reliable.
