AM/FM Tuner Module (AFM)

Downloading software and replacing the control module
New software can be downloaded into the AM/FM tuner module (AFM). 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.
In 4-door vehicles the control module is located on the parcel shelf. In 5-door vehicles the control module is located under the right-hand rear side window.
After replacing a control module, the unique ID number of the control module must be programmed in the central electronic module (CEM).
