Stuck radio volume knob = $10,000 repair?

I would be very surprised if the volume control or any variable control (e.g. tuning) used a resistive wiper type potentiometer. That's just so old school, even pre-solid state era.

I was attempting to be nice and humble with my response. I guess my form didn't achieve what I had intended.
I'll put it this way - it sure looks to me like a PCB mounted encoder controller (with a two-pin push On/Off circuit)!
Unlike inside a typical variable resistor potentiometer that has a moveable wiper that interacts with a resistive surface that can wear and get dirty over time and with use, an encoder doesn't have a surface that gets worn or dirty. Therefore, I don't think it'd be necessary nor wise to attempt to spray contact cleaner inside it or on it..

Wow, just read this thread. Amazing. Are those problems still happening on the 2016 or newer models?

@websurfer - A stuck volume control **** (or tuning control ****) will continue happening as long as people pound, shove or depress the **** with way too much force. The problem is not the **** or the head unit equipment - the problem is careless, uncaring (probably emotional) people that pound on or shove the **** too hard!

Thanks for the info.
I'm very pretty gentle with my usage on the radio so I hope it will last a long time.

On a 2nd note in my 1st post, I said that being heavy handed on the control both in and out, and side to side was likely the cause on 99% of the problems here in the 1st place. Also that it would be the best to prevent the problem in the 1st place.

Because of this forum, I do not turn off my radio at all. I will mute it if I do not want to hear anything. In a way, I wonder without using the on/off button on a regular basis, if that would possibly make this button more likely to stick. I am not risky enough to find out, but I appreciate BCLexus and of course Peasodos for always being helpful with solutions.

Although if it does get stuck, I'm tempted to swap everything over to a 2018+ unit haha
