I have the same problem! Glad to hear all it needs is a simple cleaning.

i pulled the knob off and everything looked very clean. I don't really see how I could clean out the gears "inside" - they looked to be buried under some cover tyhpe thing..

when i pulled off the knob I saw the silver "nub" that it affixes too - it had little gear teeth...they were spotless. there is a clear plastic cover thing that I could see though and see some kind of mechanism behind - but i couldn't see any way to get that off. i poked around with a small screwdriver and this clear thing did NOT appear to come off.

by making fine adjustments/clicks/turns of the "nub" while the knob itself was removed, I could make one small "click/turn" and hear the head unit register the click with some kind of noise inside..but it woudl make errors in terms of which way it went - it would go bakcward when I clicked forwards, vice versa.

i wonder if it is some sort of problem "deeper" inside the knob mechanism thatn I can go? unless I can pull off more than just the knob - I think it's something more than gunk under the knob...

Same problem here - and I just wrote it off as as idiosyncracy of the radio. Sometimes I can verrrry slowly and deliberately move the knowone click and get it to go to the next track, but it typically seems to skip a few or not move at all. Now I usually just turn it off and enjoy the exhaust note.

Try puling the faceplate and cleaning the contacts on the plate and HU and then put it back paying attention to properly align it with the contacts, bet this fixes it.

does the faceplate actually come off? is it supposed to or would I be opening/taking something apart that isn't really supposed to come off??

The Faceplate is made to be removed. This is for security and Porsche provided a nifty logo'd storage case for it - looks like a sunglass case - pn# 996.645.190.00, but most of these have gotten lost through the years and few 2nd owners have it when they get their car, though you can still order replacements.

Below is a bmap of the page in the becker manual for removing the faceplate.
