has anyone found that the volume knobs both on the steering wheel and the console need to be replaced? is this an easy fix or a writeup for it? Sounds like a small thing but sometimes these can be intricate if a lot of other parts need to come out.

Specifically, on the steering wheel the rubber on the volume knob is worn out. I use it frequently.

On the display which I rarely use, when I turn the volume knob (whether its pressed in or not) sometimes seems to "slip" and the volume might go up or down irrespective of whether I'm turning it clockwise or counterclockwise. I'm more confused by this one since I don't use it often so its not a normal wear and tear issue like the steering wheel knob.

Thanks
