Audio unit





Hint: The image above is a general image and does not show the internal location of the control modules. For location see Design and Function, the MOST network or Infotainment Control Module (ICM).

The integrated audio module (IAM) functions as a stereo system in the vehicle and is connected to other control modules on the MOST network.

Integrated audio module (IAM) controls settings for:
- Volume
- Bass
- Treble
- Balance
- Fader
- Equalizer
The Integrated Audio Module (IAM) manages the playback of compressed music formats from CDs (does not apply to Performance). Support available for the following formats:
- mp3
- wma
The integrated audio module (IAM) can play music via the AUX input.
For the XC60 and S80/V70/XC70 from structure week 200846, there is support for music playback via a USB/iPod connection in the tunnel console (does not apply to Performance). There is support for playback of the following formats:
- mp3
- wav
- wma
For the XC60 and S80/V70/XC70 from structure week 200846, there is support for the reception of digital HD-radio (does not apply to Performance).
HD radio is transmitted digitally on the AM respectively FM wavelength in USA. The Integrated Audio Module (IAM) automatically switches to digital HD radio reception if there is a current frequency and if the function for HD-radio is highlighted in the user menu.
When the Integrated Audio Module (IAM) receives digital HD radio, a symbol appears for HD radio in the Infotainment control module (ICM).
The integrated audio module (IAM) lowers the volume from the current source when the control module receives other audio information, such as indication from the parking assistance function or phone call.
If the vehicle is equipped with a navigation system, voice information is played via the existing speakers.

Remote control




The steering wheel remote control (standard/option) is directly connected to the steering wheel switch right (SWSR). The remote control can be used to change volume (increase/decrease) and change the set radio stations. During CD or USB/iPod playback, the buttons are used for track selection. The steering wheel switch right (SWSR) communicates with the infotainment control module (ICM) via the LIN bus. ICM then sends the signals on to the integrated audio module (IAM) via the MOST network.

Audio remote control (option)




A separate, wireless remote control is available as an option. This can be used to change volume (increase/decrease) and change between the different set radio stations. During CD USB/iPod playback, the remote control buttons are used for track selection. With the CD changer, the remote control can also be used to change discs. You can also search for a specific frequency, store radio station presets, perform Autostore and select source.
