Subwoofer Module (SUB)

Downloading software and replacing the control module

New software can be downloaded into the subwoofer module (SUB). 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's central database does not correspond, the database is updated with the vehicle's configuration. When this is complete, new software is downloaded.
The subwoofer module (SUB) is on the left-hand side in the cargo compartment.
Select download MOST network for a total download of software to the vehicle.
