Can I Disable My Mobile Phone’s Visibility After Pairing Process? - Porsche PCM Manual

5. Frequently asked questions (FAQs)
Can I disable my mobile phone's visibility after
the pairing process?
Yes. Visibility is only required for pairing, which only
needs to be done once before the first connection. Once
you have paired your mobile phone with the car, subse-
quent connections will be established even if visibility
is disabled. Visibility can be enabled and disabled under
'PHONE/OPTION/SET PHONE/Bluetooth
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 CDR-31/PCM in the mobile phone's
device list. This device list is found under the
Bluetooth settings 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/CDR-31. Make also sure that the
PCM/CDR-31 is in the Bluetooth
the mobile phone will be able to 'see' it there. In
addition, the corresponding menu item in the PCM
must be activated, in Bluetooth

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. Some phone respond to a pairing request by the
CDR-31/PCM only when their screen is active and
visible.
Can I pair a second phone with the car?
Yes. Before pairing a second Bluetooth
you should terminate the connection with your first
device. One way of doing this is to disable the
Bluetooth function on the first device for the time of
®
pairing the second one.
What happens if there is more than one Bluetooth
phone in the car at the same time?
The preparation for mobile phone can only be connected
with one phone. You can, however, pair up to five devices
in the car and then actively switch between these
devices. When the system is switched on, it automati-
cally searches for the last connected mobile phone. If it
does not find this device within 15 seconds, the system
then searches for the other paired phones.
