2004 PORSCHE 911 TURBO CD changer

Engine cooling.
The 911 Turbo engine features
cross-flow water cooling with fully
integrated coolant management.
This technology ensures a
consistent flow of coolant to each
of the engine’s cylinders. All
coolant passages are integral to
the block, thus eliminating the
need for external hoses. Each
cylinder receives a fresh supply
of coolant which has not been
pre-warmed by the engine. As well
as improving reliability, this
helps to minimise maintenance
requirements. Waste heat from
the oil is transferred to the
coolant via two oil/water heat
exchangers. The coolant is routed
through twin radiator modules
ahead of the front wheels and a
centrally placed unit in the nose.
Engine management.
Optimum performance is assured
at all times with the aid of
the Motronic ME7.8.1 engine
management system. On the new
911 Turbo, this powerful ECU is
responsible for all engine-related
functions and assemblies (see
diagram). Key among these are
the Variable Turbine Geometry
(VTG), VarioCam Plus and
electronic throttle system – one
of the essential prerequisites
for the standard Porsche Stability
Management (PSM). The results:
optimum economy, emissions
and performance, regardless of
driving style.Another important task performed
by the engine management
system is cylinder-specific knock
control. By preventing pre-ignition
at high engine speeds, this
function can avert costly damage
to the pistons and cylinders. Since
temperatures tend to vary in
different parts of the engine, each
cylinder is monitored separately.
If a risk is detected, the individual
ignition timing is adjusted.
The EU-compliant on-board
diagnostics system provides
continuous fault detection and
early warning for the exhaust
and fuel supply systems. The
resulting benefits are active
prevention of harmful emissions
as well as consistent rates of
fuel consumption.

Luggage compartment.
In addition to the loadspace in the
rear seat area, the new 911 Turbo
has a 105-litre front luggage
compartment. The bulkhead
panelling conceals the standard
audio amplifier for the BOSE
®
Surround Sound System, as well
as the DVD drive for the
navigation module. The optional
CD autochanger is installed on the
right-hand side of the compartment
(looking forwards). The entire
compartment is lined with high-
quality, scratch-resistant
materials.
Roof transport system.
The optional roof transport
system is made from lightweight
aluminium, making it extremely
easy to fit. It is also styled to
match the exterior design as well
as the car’s aerodynamics. The
basic load-carrying bars can
be
combined with a range of
attachments from Porsche
Tequipment, including a roof box
and carriers for bikes, snowboards
and skis. Maximum roof load is
75 kg.
Anti-theft protection.
Standard anti-theft equipment
on the new 911 Turbo includes
an engine immobiliser with in-key
transponder. The comprehensive
alarm system features contact-
sensitive exterior protection and
radar-based interior surveillance.
Vehicle tracking system.
Optional protection includes a
factory-fitted preparation enabling
future installation of a vehicle
tracking system from Porsche
Tequipment. In the event of theft,
the system enables remote
tracking of the stolen vehicle
across most European countries.
Also requires special wiring
loom and higher capacity battery.

Satellite navigation.
The PCM system on the new
911 Turbo includes satellite
navigation as standard. The DVD
drive for navigation data is
neatly concealed in the luggage
compartment. The standard
CD drive in PCM can therefore be
used exclusively for audio CDs.
Special features on the GPS
navigation module include
dynamic route guidance with TMC
(Traffic Message Channel).
This function provides a visual
overview of traffic congestion as well as automatic calculation
of alternative routes. Another
feature of the navigation module
is the easy-to-use menu structure.
After you enter your destination,
the system automatically
establishes your current position
before guiding you there via the
best possible route.
The DVD drive offers faster data
access, and therefore faster
route calculation, than equivalent
CD systems. The number of zoom
levels has also been increased
to make map reading easier.
Navigation data for most European
countries is included on a
single DVD.
Navigation expansion module.
In combination with PCM, this
optional expansion module
enables automatic navigation
along a previously recorded route
(reverse route navigation) as
well as compass and GPS-based
navigation in regions not covered
by your navigation DVD.
The standard 911 Turbo is
equipped with Porsche
Communication Management
(PCM) featuring a high-resolution
colour display. PCM is an
integrated system combining
radio, CD player, audio controls,
on-board computer and satellite
navigation, as well as optional
CD autochanger, telephone
module and electronic logbook.
The integral CD drive is also
compatible with MP3 audio files.
In addition, PCM provides direct
control of the performance display
and memory function included
with the optional Sport Chrono
Package Turbo.Radio features include 20 FM
and 20 MW presets, Dynamic
AutoStore, and RDS two-tuner
frequency diversity. The two-tuner
function uses one tuner to play
the selected station and another
to search for the best possible
signal throughout your journey.

Antenna diversity.
The PCM package includes four
separate antennae which are
discreetly incorporated within the
windscreen glass. This simple
solution enables the twin-tuner
radio system to find the strongest
possible signal, thereby enhancing
FM reception.
On-board computer.
The PCM computer offers a wide
range of information, including
average fuel consumption, average
speed, range till empty, journey
time and external temperature.
It can also be used to view data
from the optional Tyre PressureMonitoring (TPM). The computer
is operated using a separate
control stalk, displaying key infor-
mation in the central instrument
dial. The same control stalk
is used to operate the timing
functions in the optional Sport
Chrono Package Turbo.
Electronic logbook.
This optional addition to PCM
enables automatic logging on
every journey of mileage, route
distance, date and time as well as
starting location and destination.
Data can be downloaded from
PCM via an infrared port and
processed on a computer using
software included with the
package. This easy-to-use option
fulfils all the requirements for
automatic logbooks as specified
by the German revenue authorities.
Telephone module.
The optional GSM telephone has
a 12-digit keypad and a hands-
free facility offering excellent callquality. The hands-free microphone
is located next to the steering
column and is ideally positioned
for the driver. The telephone
system supports SMS (text)
messaging as well as card-free
calls to emergency services. An
optional passive (keyless) handset
with leather-trimmed console
enables clearer communication
as well as greater privacy when
making a call.
CDC-4 CD autochanger.
This optional CD autochanger has
a total capacity of six audio
CDs and installs beneath a panel
in the luggage compartment.
An autochanger preparation is
included as standard.
