Digital audio broadcastingGENERAL INFORMATION
Digital radio reception
DAB radio is very different from normal AM/FM radio in both operation and sound quality. The DAB network is designed to provide near CD quality from radio broadcasts. In most locations DAB signals are available without hiss, crackle, pop or interference, and no fading or overlap.
DAB radio can significantly increase the number of radio channels/stations available. The DAB signals are transmitted to most major cities, towns and motorway networks.
Radio signals travel in a straight line so large obstacles, such as tall buildings, can shield the vehicle from the signal, causing temporary loss of reception (known as dead spots).
Digital radio is transmitted from regional transmitters. Some local channels are not available outside the range of their transmitters. If you want to listen to local channels as you move around the country, use the auto-tune function (AUTO) to build new channel lists. For more information on the auto-tune function. See CHANNEL AUTOMATIC TUNING (page 262).
Note: If any auxiliary electrical equipment is connected to the vehicle, then this may reduce the DAB radio sound quality.

EnsemblesUnlike AM/FM radio, DAB transmits several channels/stations on a single frequency. A group of channels is known as an ensemble. Ensembles may consist of six or more channels (national or local). Some may have sub-channels offering several listening options.
When scrolling through the channels the sub-channels will appear in order, and can be selected in the same way as the channels. If reception is lost when the vehicle is in motion select AUTO to build a new list of ensembles.
The table below provides an example of the ensembles, channels and sub-channels available in one location.

CHANNEL AUTOMATIC TUNINGNote: When you first use the DAB radio, you will be unable to listen to any digital broadcasts until you have completed the auto-tune process.
In DAB mode, select DAB search, then select Auto-tune to start automatic tuning and build a list of all the digital ensembles and channels that are available in your region.
While automatic tuning is running, the message Auto-tuning will be displayed on the touch-screen, along with a percentage complete. When tuning is complete, the first channel found will start playing.
Note: The auto-tune process can take longer than one minute to complete.
To update the list of local channels when you move to a different region, select Auto-tune again. You can also add local channels as presets to minimise the need for auto-tuning as you move location.
CHANNEL OPTIONSTo receive digital broadcasts, short press the SOURCE button repeatedly to toggle between the available sources, or briefly touch the DAB Radio button on the touch-screen. See AUDIO CONTROLS (page 260).
Choose DAB1, DAB2 or DAB3 to receive digital radio broadcasts. The three DAB sources enable you to preset up to 18 different channels. See PRESET BUTTONS (page 265).
The channel that was last played on your chosen digital source will be selected for playback automatically.
Note: If this is the first time you have used DAB radio, you must first build a list of available channels using the auto-tune function.
Digital radio channels are organised into groups called ensembles. Some channels may sometimes provide one or more subchannels.

If the digital radio signal is lost or the system takes time to tune in to a channel, then the display screen will show the message No reception.
The problem may be caused by a temporary problem, such as buildings or trees blocking the signal, or it might be a problem with the broadcast service operator. Try tuning to an alternative channel and return later to see if the problem has been resolved. If you are unable to tune to any other channels, switch off the audio unit and then try again.
Finding a channel
Briefly touch one of the channel seek buttons to select the next available digital channel. The seek up button selects the next channel, the seek down button selects the previous channel.
Note: If the next or previous channel is in a different ensemble, then there will be a pause before the channel is located. The message Searching... is displayed on the screen.
On the touch-screen, if channels have been preset, select one of the six preset buttons to start playing that channel. If no channel has been preset, the button will display ---.
Finding a subchannel
If subchannels are available under the current channel, the subchannel arrow icon (1) is displayed at the top of the touch-screen and the Subchannel button is enabled.
To access the subchannels, select the downward-pointing arrow (2). Select the seek buttons (3) to find the next/previous subchannel.
To return to the channel tier, select the upward-pointing arrow.
Note: When you select and play a subchannel, the subchannel icon is replaced by SubCh.

FM trafficThe FM traffic option detects the presence of local traffic announcements on FM stations. As soon as an announcement is received, radio reception or CD play will be interrupted. At the end of the announcement, radio or CD play will resume.
Select On or Off to enable or disable the FM traffic option.
Note: The audio unit switches to an FM broadcast for the duration of the announcement, so there may be a temporary loss of sound quality.
Link DABRegional ensembles containing a list of local digital channels are broadcast by a variety of regional providers. For example, the Leicester and Coventry regions in the UK are currently supplied by Now Digital, whereas Birmingham is supplied by CE Digital.
A channel (for example, Chill) in two different regional ensembles will share an identification if broadcast by the same provider (for example, Chill Coventry and Chill Leicester). If channels are being broadcast by different suppliers, then they will not share the same identification (for example, Chill Coventry and Chill Birmingham).
If you move from one region to another and Link DAB is enabled, the DAB radio will attempt to retune to a channel with the same identification in a different ensemble.
If the signal strength for a local channel falls below an acceptable level, the audio unit will automatically search other available ensembles for another channel with the same identification.
If an alternative channel is found in another ensemble that is also in your current channel list, then the new channel is tuned automatically after a few seconds. If a channel is not found after a few seconds, then No reception is displayed on the screen.
The word Link is displayed at the top of the touchscreen to indicate that Link DAB is enabled.
