How to reset the iDrive system in the BMW 7 Series?

I am having trouble with the iDrive system in my BMW 7 Series. It freezes frequently and I am unable to access any features. How can I reset the system?

First, try pressing and holding down the power button for 10 seconds to force a restart of the iDrive system. If that doesn't work, you can also try disconnecting the car battery for 10 minutes and then reconnecting it. This will reset the iDrive system completely.

Another option is to go into the iDrive system's settings and perform a factory reset. This will erase all personalized settings and data, so make sure to backup any information you want to keep beforehand.

If none of these options work, it may be a hardware issue. I recommend taking your car to a certified BMW dealership or mechanic for further assistance.
