There are two models of the RTI system, one
old and one new version.
The older system has two units, the RTI control
unit and the CD changer. In the new system the
CD changer has been replaced by a DVD player
which is integrated with the RTI control module.
The control module is located in the left section
of the cargo compartment.
CDs cannot be played in the RTI system. This is
because the system is not compatible with
these types of disc.
The RTI system communicates partly with
components which are directly connected and

Signals
partly with other control modules and
components via serial communication and
Control area network (CAN).
The control module checks activations and input
and output signals using an integrated
diagnostic system A diagnostic trouble code
(DTC) is stored if the control module detects a
fault.
Diagnostic trouble codes (DTC) are stored in the
control module memory. The data can be read
off using the diagnostic tool.
A simple way to check that the RTI components
are both powered and grounded is to try to
insert or remove a CD or DVD. The RTI system
is powered and grounded if the disc can be
inserted and removed. If this is not functioning,
check the power supply and ground for the RTI
system.
The RTI system has an internal communication
system, Melbus. Communication is between the
RTI unit, the TV receiver, the CD changer and
the audio module.
Melbus communication consists of three
different signals:
MSCK, clock signal

MDATA, data signal which transmits
information
MBUSY, indicates whether the data signal is
engaged or not.

For information, also see Signal specifications.
The table below summarizes input and output
signals to and from the RTI control module. The
signal types are divided into directly connected
signals, serial communication and Control area
network (CAN) communication. The illustration
below displays the same information with the
Volvo part numbers.

Design
the GPS aerial

The data transmitted from the GPS aerial to the
RTI control module consists of signals received
from GPS satellites.
There is a signal booster (aerial amplifier)
integrated in the GPS aerial. The signal is
strengthened before it is transmitted to the GPS
receiver which is integrated in the RTI unit. The
GPS also adapts the impedance of the signal.
The RTI system and the GPS aerial require
contact with at least three satellites to be able to
calculate the position of the car. The RTI system
can communicate with up to eight satellites at
the same time.
The position calculated from the GPS satellites
is accurate to within +/- 30 meters.
View the GPS information under system settings
to check how many satellites are available.
The power supply is from the RTI control
module. The power supply uses the same high
frequency wiring as the GPS information that is
sent to the RTI unit.
The GPS aerial is located in the parcel shelf in
S80 and S60 models. In V70 and V70XC models
it is located in the dashboard.
Note! If there is no GPS signal, the signal should
be checked outside. The signal may be blocked if
the car is indoors. Large objects on the parcel
shelf or tinted rear windshields may also be the

cause.

The role of the TV receiver is to manage the
incoming TV signals from local TV transmitters.
There are three models of the TV receiver:
One for Europe (PAL)

One for U.S.A. (NTSC), only applies to the
S80 Executive
One for Japan (NTSC).
-
-
-
The European TV receiver can handle three
different PAL systems. The menu system on the
TV receiver is used to change the PAL system
settings. See the RTI manual for further
information.
The TV receiver sends the received TV signals
on a serial bus (Melbus) to the RTI system. The
RTI system handles the incoming signals and
sends them to the display screen.
The TV receiver transmits the TV sound on a
serial bus (Melbus) to the audio module via the
RTI unit.
Station settings, colour, TV picture size and the
screen contrast are set using the audio module
or the remote control.
The TV receiver is located in the left section of
the cargo compartment in the S80 and S60. In
V70 and V70XC models it is located behind the
rear seat.

The role of the RTI control module is to
calculate the position of the car based on the
signals it receives from the GPS aerial, the
speed signal from the central electronic module,
the gear position and the gyro. The RTI system
then works out a route for the selected
destination.
There are two models of the RTI system, one
old and one new version.
The older system has two units, the RTI control
unit and the CD changer. In the new system the
CD changer has been replaced by a DVD player
which is integrated with the RTI control module.
There is an integrated three dimensional piezo
electrical gyro in the RTI control module. This
manages data about the movements of the car,
such as whether any turnings are made.
Data transmitted on the CAN to the RTI unit
from different nodes is:
vehicle speed

wheel rotation counter
reverse (reverse) gear position
signals from the steering wheel controls
radio mute
background lighting.
-
-
-
-
-
-
Gyro and wheel rotation counters are used to
calculate the position of the car for shorter
periods, if communication with the GPS
satellites is lost in a tunnel for example or to
assist when there is no GPS signal.
Used in conjunction with map matching, GPS
navigation, the gyro and the speed signal, the
position can be calculated to an accuracy of +/-

10 meters from the position indicated on the
screen.
The traffic message channel (TMC) receiver is
integrated in the RTI unit. TMC is a standardised
code system for traffic messages such as road
works. The Japanese equivalent is called FM
multiplex.
There is no traffic information system in the USA.
The TMC aerial is located in the right-hand
section of the rear bumper.
The control module is located on the left-hand
side of the cargo compartment.
The RTI (road traffic information) control module
can be diagnosed.
There are two sizes of display screen. There is a
6.5" wide screen LCD screen and a 5" LCD
screen.
All signal information to the screen is from the
RTI control module.
The screen has an infra red eye above it which
is used for communication with the remote
control.
The menu system for the screen can be
controlled using the RTI buttons on the reverse
of the steering wheel or using the remote
control.
The screen is positioned in the middle of the
dashboard.

Remote control
Function
GPS navigation
A six disc CD changer is used together with the
RTI control module on the older RTI system.
This unit only handles CD discs with map
information, not music CDs.
The discs contain information about road
networks, streets, voice guiding and the
software required for the system to function.
The CD changer communicates with the RTI unit
on serial buses (Melbus).
There is a dedicated remote control for the RTI
unit. The function of the remote control is the
same as the steering wheel buttons.
There is also a separate remote control for the
TV receiver which can be used to store and
change TV stations, the colour, the size of the
picture and the contrast on the screen.

The GPS aerial (16/47) receives signals from a
minimum of three and a maximum of eight GPS
satellites. These signals are then sent on to the
GPS receiver in the RTI control module (16/45).
The position of the car is calculated and a route
is displayed for the selected destination.
Data for voice guiding for the selected route is
transmitted on the serial bus (Melbus) between
the RTI control module and the audio module
(16/1).
In order for the RTI system to select a route, a
DVD (16/45) or CD (16/48) must be available
with the road network. For CD changer systems
the data is transmitted on a serial bus (Melbus)
to the RTI.
Data about speed, the wheel rotation counter
and handbrake is sent using CAN
communication from the central electronic
module (4/56), ABS (4/16) and driver
information module DIM(5/1).
Data is sent to the display screen (16/46) from
the RTI control module on serial buses.
Commands from the remote control are sent
from the display screen (16/46) to the RTI unit
Page 9 of 13 "VCC-139154 EN 2006-10-26"

Traffic message channel (TMC) reception
(16/45) on a serial bus (remocon signal).
The menu is accessed and used via the buttons
on the reverse of the steering wheel. Data is
sent from the steering wheel module (3/130) to
the RTI unit (16/45) via the Control area network
(CAN). There are three steering wheel buttons
which are used to control the menu on the
screen. There is a four-way switch on which
each part of the switch moves the cursor
upwards, downwards, to the left or to the right.
There is an ENTER button and a BACK button.
When a new GPS aerial is installed for the RTI
system, it may take up to 15 minutes before the
GPS receiver has the correct information.

The role of the TMC receiver is to receive traffic
information on the FM wavelength. The
Japanese system is called FM multiplex.
The TMC receiver is integrated in the RTI
system and is connected to the aerial system for
the FM radio.
There is no traffic information system in the USA.
The TMC data signal is received by the TMC/FM
multiplex aerial (16/68) which is located in the
rear bumper. The signal is boosted by the aerial
amplifier (16/67) before it is sent to the RTI unit
(16/45). This data is displayed on the screen
(16/46).

TV reception
RTI diagnostic functions
General

The TV aerial pattern on the rear windscreen
(16/54 for the V70/V70XC, 16/9 and S60/S80)
receives signals from the TV network. These
signals are boosted in the TV aerial amplifier
(16/71) which sends the signals to the TV
receiver (16/36). The signals are sent on to the
RTI unit (16/45) on a serial bus (Melbus). The RTI
unit send the signals containing sound
information to the audio module (16/1) on a
series bus (Melbus) and signals containing
picture information to the display screen (16/46).
When the vehicle speed exceeds 7 km/h the RTI
changes to navigation automatically.
The SOURCE button on the audio module (16/1)
or on the remote control is used to set the TV
stations.
The RTI control module has a built-in diagnostic
system, the Volvo on-board diagnostic (OBD)
system, which continuously monitors itself and
the input and output signals.

Diagnostic trouble codes (DTCs)
Reading and erasing diagnostic trouble codes (DTCs)
Reading off the control module identification
Downloading software and replacing the control module

A diagnostic trouble code (DTC) is stored if the
RTI detects a fault. A fault which is detected in
the latest driving cycle is defined as permanent.
Other detected faults are defined as intermittent.
Stored diagnostic trouble codes (DTCs) can be
read off and erased using this function.
Diagnostic trouble codes (DTCs) can only be
erased when all diagnostic trouble codes (DTCs)
have been read at least once.
VADIS identifies the control modules by reading
off a number of codes of RTI memory.
The codes contains information about the RTI
control module's:
hardware P/N (control modules without
software)
hardware serial number (control modules
without software)
software P/N
P/N diagnostic software.
-
-
-
-
New software can be downloaded into the RTI
control module. When ordering software, the
hardware and the software in the car is
compared to the Volvo central database. If the
comparison is OK the software is downloaded
to the control module.
If the comparison between the car and Volvo
central database does not correspond, the
database is updated with the configuration of
the car. New software is downloaded after the
update is complete.
All other software required for the RTI system to
work is on the CDs or DVDs.
The following applies when downloading new
software versions:
The early version CD for structure weeks -
