GNS-430W knobs coming loose?
I noticed today that the right knobs (for display nav and menu manipulation) on my 430W are noticeably looser than the left knobs (for radio dialing). They still controlled the unit properly and weren't (quite) about to fall off, but they're definitely not "solid" like they're supposed to be. I started to notice this a flight or two ago, but at first it seemed okay...just one pair of knobs felt slightly different from the other. Now, it's clear that something's wrong, and it's getting worse.
I looked for a set screw that I could check, but didn't see one. It's not obvious to me whether the knobs are designed to be "user-serviceable".
Anyone have a hint or tip on how to re-tighten the knobs? Is this something I need to take it to the avionics shop for?
