The display in the iDrive is not possible.
This would only be possible with other hardware and much more effort. In addition, it would “intervene” in the bus system of the vehicle and the electronics of the iDrive. We wanted to deliberately do it without the potential “sources of error”. Moreover, we wanted to specifically forego the difficult to reverse changes to the vehicle cabling, especially in the interest of our customers.
You can use the interface to play wireless music in the sound system of your car, but neither display songs on the iDrive nor can you forward or reverse songs through the buttons on the steering wheel.
