Satellite Radio (SDARS)

R

Touch the Keypad icon.

A numeric key pad is displayed, enabling
the manual entry of the channel number.
Press the appropriate number keys.

Only numbers that make up a valid
channel number are highlighted and
available for selection.

Note: In the event that the selected
channel has been removed by the
Broadcast operator, then an INVALID
COMMAND message is shown and the
previous playing channel is reverted to.
This may occur if the broadcast operator
changes the active channel whilst the
vehicle is powered. The valid playlist is
updated each time the system is powered
up, therefore the next time the system is
powered up, the playlist will be updated
thereby preventing the invalid channel
from being selected.

No Service is displayed if no signal is
received. It means that no satellite or
ground signal is being received and is not
the same as No Subscription, which
directs the user to call SIRIUS. Ensure
that the vehicle is not in an enclosed
space (such as a garage).

To select station by category touch the
CAT icon, and then touch the icon for the
desired category. The system will then go
back to the previous screen but with the
category displayed in square brackets i.e.
[ROCK]. The brackets are removed after
30 seconds if no further changes are
made.

If a different category is selected from that
currently being played, then the playing
channel will become the first active
channel in that category.

Station presets - setting.

There are 2 screens (SAT1 and SAT2)
each with 9 icons giving a total of 18
available presets.

To save a station as a preset, press and
hold the selected icon until the preset is
stored and highlighted.

To change a preset, touch the chosen
icon and select the desired station either
via category or manually. Then press and
hold the selected icon until the new preset
is stored.

Note: If manual tuning is used and a
channel is selected that is an existing
preset, the preset will highlight. If the
same channel is stored in more than one
preset (on different screens for example)
and manual tuning is performed, the first
preset will highlight.

Selecting a station by preset

Press the preset icon representing the
desired station. The radio tunes to the
selected station and the station
information is displayed.

When a preset is successfully selected, it
is highlighted in orange

Note: There are 2 preset screens (SAT1
and SAT2), with 9 presets on each. The
icon (arrowed) identifies the next preset
screen for selection and not the screen
currently being displayed.

Tuning information

It must be noted that Satellite Radio
differs from FM in that tuning is NOT
instantaneous.

Satellite Radio (SDARS)

R

The information is sent in digital form in
packets which must be decoded. This
process can take several seconds to set
up. Therefore when a new channel is
tuned to, the audio will mute until the
information has been decoded into
music/speech. Normally this takes less
than 1 second but can take up to 5
seconds.

It should also be noted that the additional
information (artist, album etc.) is
broadcast at a different rate to the audio.
Therefore there will be a delay after the
audio starting and the display screen
updating. This delay is normally 3 to 4
seconds but can be up to 20 seconds.
This is a function of the way the radio
channels are broadcast.

Note: The screen information is updated
only when a change takes place. When a
new channel, or a new track on a current
channel, starts playing then the previous
artist/song title etc. will continue to be
displayed until an update is received. This
is a function of the way the radio channels
are broadcast

Digital Radio

HD (High Definition) radio

HD radio provides digital audio signals to
improve sound quality.

Note: HD radio is also known as IBOC (In
Band On Channel).

The HD signal is carried by an existing
AM/FM signal. This means that if the HD
signal is unavailable the analogue (AM/
FM) signal is automatically selected.

When the audio unit is tuned to a HD
signal the station name shown in the
display will be prefixed by HD.

HD radio operation

Using the HD radio system is no different
than using the standard radio. So for
storing stations, manual tuning etc. see
RADIO WITH TOUCH-SCREEN, 295.

Note: Secondary services can be
received on digital channels. Their
availability is controlled by the channel
provider. If a HD channel features
secondary services, they will be displayed
as HD1, HD2, HD3 etc. depending on how
many are available.
