GENERAL INFORMATION

Digital radio reception

Digital audio broadcasting (DAB) provides a 
clear signal with minimal interference, hiss or 
fading. After a channel (or station) has been 
tuned and stored, you do not need to retune. 

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 
terrestrial transmitters. Some local digital radio 
channels are not available outside the range of 
a transmitter. If you want to listen to new local 
channels as you move around the country, you 
will need to use the auto-tune function (AUTO) 
to build new channel lists.

Digital radio channels are organised into 
groups called ensembles (also known as 
multiplexes). Some individual channels may 
also provide a number of subchannels. For 
example, if several sports events are being held 
simultaneously, the channel may temporarily 
choose to broadcast each different event on a 
separate subchannel.

will be unable to listen to any digital stations 
until you have used the auto-tune function.

Press and hold the AUTO button to start

While automatic tuning is running, the 
message Auto-tuning will be displayed along

AUTO button again.

To receive digital broadcasts, press and release

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, before you can select a channel, you need 
to build a list of available channels using the 
auto-tune function. See CHANNEL 
AUTOMATIC TUNING (page 236).

Digital radio channels are organised into 
groups called ensembles and some individual 
channels may provide a number of 
subchannels. You can search for channels, 
subchannels or ensembles to find the digital 
broadcast you require.
