Audio system
To protect the system, do not use a USB hub.
The system builds playlists (in temporary
memory); this operation can take from a
few seconds to several minutes at the first
connection.
Reduce the number of non-music files and the
number of folders to reduce the waiting time.
The playlists are updated every time the ignition
is switched off or a USB memory stick is
connected. The lists are memorised: if they are
not modified, the subsequent loading time will
be shorter.
USB socket
Located on the central console, this
socket is used only to power and
recharge the connected portable device.
Auxiliary socket (AUX)
Connect a portable device (MP3 player,
etc.) to the auxiliary jack socket using an
audio cable (not supplied).
First adjust the volume on your portable device
(to a high level). Then adjust the volume on your
audio system.
Controls are managed via the portable device.
The functions of the device connected to the
“AUX” socket are managed directly by this
device: it is therefore not possible to change the
track/folder/playlist or manipulate the playback
Radio, toggle up or down continuously: scan up/
down frequencies until you release the button.
Media, toggle up or down: select next/previous
track.
Media, toggle up or down continuously: fast
forward/rewind until you release the button.
Refuse an incoming call.
End the call in progress.
Radio
Selecting a station
The exterior environment (hills, buildings, tunnels, car parks, underground location,
etc.) may block reception, including in RDS
mode.
This behaviour is normal in the propagation of
radio waves and does not indicate any fault
with the audio system.
Press the "RADIO" button to select the
FM or AM waveband.
Briefly press one of the buttons to
automatically search for a lower/
higher frequency.
Turn the knob to manually search for a lower/higher frequency.
Press the knob to display the list of
stations received locally.
Turn the knob to select a station and press to
select it.
Memorising a station
Press the "RADIO" button to select the
FM or AM waveband.
Press the "A-B-C" button to select one of
the three memorised station levels.
Press and hold a button to memorise the
station being listened to.
The name of the station is displayed and an
audible signal confirms the memorisation.
Press "INFO" to display the information of
the station being listened to.
RDS
RDS, if displayed, allows you to continue
listening to the same station by
automatically retuning to alternative
frequencies. However, in certain conditions,
following this RDS station is not guaranteed
over the whole country, because radio
stations do not cover 100% of the area. When
the reception is weak, the frequency switches
to a regional station.
Press the "MENU" button.
Select "Regional" then press to activate
or deactivate RDS.
Alternative frequency (AF)
Select "Alternative frequency (AF)" then
press to activate or deactivate the
frequency.
When the "Regional” function is
activated, the system is therefore able to
search at any time for the best available
frequency.
Playing TA messages
The TA (Traffic Announcement) function gives priority to TA alert messages. To
operate, this function needs good reception of
a radio station that carries this type of
message. While traffic information is being
broadcast, the current media is automatically
interrupted so that the TA message can be
heard. Normal play of the previously playing
media resumes at the end of the message.
Press the "MENU" button.
Select "Traffic announcement (TA)" then
press to activate or deactivate the
reception of traffic announcements.

Updating maps
To get a map update, you can proceed as follows:
– Map refresh guarantee: if a new map
becomes available within 90 days of the first
use of the system, you can download it once
for free.
– Map update: you can buy a new version of
your system’s map.
To install a map update on your system, perform
the following four steps:
– Prepare a USB device.
– Install TomTom HOME and create a
MyTomTom account.
– Download the map.
– Install the new map.
Use a USB device instead of a mass
storage device (telephone or media
player).
To protect the system, do not use a USB hub.
Prepare a USB device
The preparation of the USB device
must be done with the engine running
and the vehicle stationary.
In order to update the map, you must have
a USB device that meets the following
requirements:
– The USB device must be empty.
– The USB device has 16 GB of available
space.
– Use only USB devices in FAT32 format (File
Allocation Table).
– Do not lock the USB device and check that
files can be saved on it.
To prepare the USB device, proceed as follows:
► Make sure that the map you want to update is
active on your navigation system.
If the navigation system has multiple maps and
you want to update a map that is not currently
active, start by activating it.
► Select “Change map” in the “Settings” menu
of the navigation application.
► Select “Navigation updates” from the
“Settings” menu.
► You must indicate whether you want to
prepare a USB device to download updates.

Voice commands
Information - Using the
system
Instead of touching the screen, you can
use your voice to control the system.
To ensure that voice commands are always recognised by the system, please
observe the following recommendations:
– speak in a normal tone of voice,
– before speaking, always wait for the "beep"
(acoustic signal),
– the system is able to recognise the voice
commands provided, regardless of gender,
tone and inflection of the voice of the speaker,
– if possible, minimise the noise inside the
passenger compartment,
– before issuing a voice command, ask any
other passengers to refrain from speaking.
Since the system recognises commands
regardless of who is speaking, when several
people are speaking simultaneously, it
is possible for the system to recognise
commands that are different or additional to
what has been requested,
– for optimal operation, you are advised to
close the windows and any sunroof present
(on versions/markets where fitted) to avoid
any external source of disturbance.
Steering-mounted controls
This button is used to activate the “Telephone” voice recognition mode that
allows you to make calls, view recent/received/
outgoing calls, display the directory, etc.
This button is used to activate the "Radio/ Media" voice recognition mode that allows
you to tune to a specific radio station or a
specific AM/FM radio frequency, play a track or
an album contained on a USB stick/iPod/MP3/
CD.
Quick voice interaction can be used if
these buttons are depressed during a
voice message from the system; it allows you
to directly say a voice command.
For example, if the system is in the middle
of saying a voice help message and if we
know the command to give the system, by
pressing these buttons, the voice message
is interrupted and it is possible to directly
say the desired voice command (so avoiding
having to listen to the complete voice help
message).
When the system is waiting for a voice
command from the user, pressing these
buttons closes the voice session.
Each time a button is pressed, a "beep"
(acoustic signal) is emitted and the
screen displays a screen page of suggestions
asking the user to say a command.
