Volvo XC90: Audio, media and internet / HD Radio™ limitations
Limitations
- Main channel vs. sub-channels (FM only): The main channel is the
only channel that can receive in hybrid mode (both digital and analog). If a
frequency has subchannels, they are broadcast in digital mode only. The main
FM channel will be displayed as, for example, "WRIF-FM HD1". The sub-FM channels
will be displayed as"WRIF-FM HD2", "WRIF-FM HD3", etc.
- Reception coverage area: Due to current IBOC transmitter power limitations,
the reception coverage area in digital mode is somewhat more limited than the
station's analog coverage area. Be aware that, like all radio transmission technology,
terrain, time of day, vegetation and buildings can have a positive or negative
effect on radio reception.
- Analog to digital/digital to analog blending: Analog to digital blending
will occur as the signal strength reaches a preset threshold in the receiver.
This will be noticeable in fringe areas (areas with weak reception) and is normal.
NOTE
There may be a noticeable difference in sound quality when a change from
analogue to digital or digital to analogue occurs, such as:
- Volume increase or decrease
- Equalizer settings, i.e., Bass/ Midrange/Treble cut or boost
- Time alignment (Digital program material in extreme cases can be as
much as 8 seconds behind the analogue). This will noticeable as a "stuttering"
effect.
The above items are dependant on the broadcaster's equipment settings
and do not indicate a fault in the vehicle's radio receiver or antenna systems.
In many cases, a main HD Radio station (FM wavebands only) will also have sub-channels
offering additional types of programming or music.
Sub-channels
Example of an HD Radio station with sub-channels
If any sub-channels are available, they will listed below the main channel on
the screen...
The SiriusXM® Satellite system broadcasts from of a number of high elevation
satellites in geosynchronous orbit.
Listening to satellite radio
The digital signals from the satellites are lineof- sight, which means that physical
obstructions such as bridges, tunnels, etc, may temporarily interfere with signal
reception...
Other information:
When the center display starts up, the selected driver profile will be shown
at the top of the screen. The most recently used driver profile will be active the
next time the vehicle is unlocked. A different driver profile can be selected once
the vehicle has been unlocked...
(Certain models only.)
The temporary tire sealing system can be used to seal a puncture in a tire
or to check and adjust the pressure in the tire.
Models equipped with a spare wheel1 do not have the tire sealing
system.
