Downloading software and replacing the control module
New software can be downloaded into the accessory USB unit (AUU). When software is ordered the software and hardware of the vehicle are compared
with Volvo's central database.
If the comparison corresponds then the software is downloaded into 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 Accessory USB unit (AUU) is located behind the glove compartment down to the left on the cowl panel.
Select the MOST network for a total download of software to the vehicle.
