New 450 SL with 20 hours

[Pawleys]

Just received my 20 hour service and none of the controls on the steering wheel are working. Any suggestions would be appreciated. The nearest dealer is 200 miles away (8 hours of driving time)

Just received my 20 hour service and none of the controls on the steering wheel are working. Any suggestions would be appreciated. The nearest dealer is 200 miles away (8 hours of driving time)If nothing is working, it may be a loose connection. I've heard a few stories:

1) Turning the battery switch off and recycling the system
2) Getting a software update from the dealer
3) Getting a software update and new steering wheel from the dealer
4) May want to try removing the steering wheel cover and looking for anything loose.
5) A few people posted if you pressed the camera button, the other buttons started working. Not sure how that fixes the issue.

If you have the new 2021 heated steering wheel, there is a breaker under the dash.

There are 2 clear plastic covers next to each other, on the cover it lists what breakers are under each cover.

Pop the cover off and hit the white reset button, it fixed my steering wheel power.
