Glossary
Pairing
Before a connection can be established
between two Bluetooth® devices, they have to
undergo a one-off registration (pairing) process
for their own security. To begin this process, a
Bluetooth® search (inquiry) is initiated on one of
the devices to find all devices within range.
A list of visible devices is then displayed (device
class permitting). Once the desired device has
been selected, it will be necessary to enter
and confirm the same numeric code (passkey)
on both devices. If both devices support Secure
Simple Pairing (PCM as of November 2012),
it will only be a case of confirming whether the
six-digit codes displayed on both devices are
identical, which makes pairing considerably
easier. If pairing was successful, the devices
will now be authorised to exchange digital data
(system or user data, such as speech, audio
or video) unless the pairing is deleted on either
device.

PCM hotspot
The PCM hotspot is a WiFi hotspot in PCM that
can provide external devices in the car with an
Internet connection. The prerequisite for this
is an existing data connection via an inserted
SIM card, Bluetooth® SAP connection or
external hotspot (WiFi tethering).
Porsche Connect app
The Porsche Connect app is an app for iOS®
and Android® that can provide the driver with
additional information services that can be
operated on PCM. This includes the ability to
search for points of interest before setting out
and then automatically transfer these from
your mobile phone to your car (app destinations),
for example. Other additional services are music
services and accessing your smartphone's
calendar.

Registration status
Registration status refers to the current status
of the connection to a mobile phone network.
If the phone is connected to a mobile network,
the network name will be displayed, provided
the phone transfers this information. Other
possible statuses include 'Network search' and
'Registration failed'.
Secure Simple Pairing (SSP)
Secure Simple Pairing is a method of authorising
(pairing) Bluetooth® devices, whereby a six-
digit code is generated and displayed on both
devices. The user simply has to confirm that
the codes match each other.
Signal strength
Signal strength is an indicator of the general
reception quality of the mobile phone. It cannot,
however, be used to evaluate the quality of a
particular call because the quality of individual
CONTENTS
voice channels in a mobile network cell can vary
considerably. The signal strength is displayed
on PCM whenever the phone paired with the car
is connected to a network cell, provided the
mobile phone shares this information.
SIM card
A SIM card (SIM – Subscriber Identity Module)
is a mandatory requirement to gain access
to a GSM network. In addition to access
authorisation for the GSM network, a SIM card
may also contain other personal data
(phone book and SMS text messages). Access
to the network and the data is protected by a
PIN that must be entered on the device.
