Audio Module (AUD)

Downloading software and replacing the control module
New software can be downloaded into the audio module (AUD). When ordering software, the hardware and the software in the car is compared to the information in the Volvo central database. If the comparison is OK the software is downloaded to the control module.
If the comparison between the car and Volvo central database is not OK, the database is updated with the car configuration. When this is complete the software is downloaded.
The control module is located in the cargo compartment, behind the left wheel arch.
After replacing the audio module (AUD), the unique serial numbers of the control module are checked by the infotainment control module (ICM). The audio module (AUD) will not function if the serial number is incorrect.
Try switching the ignition off and on after downloading software if there are problems.
The MOST network is used for a total software reload.
