Switching HD on or off
The factory setting for HD radio is on. However,
when driving through areas with weak HD sig-
nals (fringe areas), you may experience that the
radio repeatedly switches between analogue/
digital and digital/analogue reception. If this
happens, it may be desirable to switch HD off.
To do so:
1. Be sure the audio system is switched on
and in AM or FM mode.
2.
Press MENU in the center console control
panel.
3.
Press ENTER to turn HD off (the X will dis-
appear from the box on the display screen).
This will disable the radio's capability to receive
digital broadcasts but it will continue to func-
tion as a conventional (analogue) AM/FM
receiver. Please note that when HD is switched
off, it will not be possible to tune to sub-chan-
nels (see the following section for a more
detailed explanation of sub-channels).
Repeat steps 2 and 3 above to reactivate HD
(an X will appear in the box on the display
screen).
Sub-channels
Example of an HD Radio station with sub-channels
In many cases, a main HD Radio station (FM
wavebands only) will also have sub-channels
offering additional types of programming or
music.
In such cases, a number will be displayed to
the right of the frequency number indicating
that the currently tuned frequency has at least
one sub-channel. The "2" in the illustration indi-
cates that you are currently listening to the first
sub-channel on frequency 93.9.
Selecting sub-channels
To listen to a station's sub-channel(s), press
the right arrow key on the center console or on
the steering wheel keypad. To go back to the
main channel, press the left arrow key. To go
to subchannel 2 (if available), press the right
arrow key.
If you are currently tuned to a frequency's main
channel, pressing the left arrow key will tune to
the next lower radio frequency.
NOTE
When the radio has gone into HD mode,
it may take several seconds before the
">" symbol (if the current frequency has
any sub-channels) is displayed to the
right of the frequency. Pressing the
arrow keys before the number is dis-
played will cause the radio to tune to the
next available radio station, not to the
current station's sub-channels.
When you are no longer in broadcasting
range of the currently tuned sub-chan-
nel,
No HD reception will be dis-
played. The radio will then be muted
and it will be necessary to tune to or
search for a new radio station.
Sub-channels can also be stored as presets,
see page 252 for information on storing sta-
tions.
If you press a sub-channel's preset button, it
may take up to 6 seconds before the channel
becomes audible. If you press this button while
