Downloading software and replacing the control module
New software can be downloaded into the audio module (AUM). New software must be downloaded when replacing the audio module (AUM). Unlike
other control modules, there is no software available for reloading the audio module (AUM). Only software for the addition of applications is available.
When ordering software, the hardware and the software in the car is compared to the Volvo central database. If the comparison is OK the software is
downloaded into the audio module (AUM).
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.
