Software updates
The Combox will enable the customer for the first time to update the software of a system component. To update the Combox, the Bluetooth profile software update must be downloaded from the BMW website http://www.bmw.com/bluetooth and stored on a USB stick. For this purpose, any conventional USB stick with sufficient storage capacity can be used. The software is then transferred from the USB stick to the Combox via the USB audio interface (option 6FL) in the center console.
