Radio knob volume UP work intermittently
I have had this annoying problem since I bought the car. Volume down works fine but volume up works randomly. Most of the times the volume UP (clockwise) turns the volume DOWN.
I have tested the entire knob with the soft little clicks you can feel. Roughly about 75% or more of the clicks or adjustments turn the volume down instead of up.
I have tried electrical contact cleaner numerous times and some compressed air but not much luck with it. It appears to help briefly but if i let the car sit for a few hours, the cleaner dries up and it starts misbehaving again.
Is my bose radio unit completely trashed?

I had the same issue repaired by Becker Auto Sound LLC in New Jersey. Factory authorized repair center. I had them add the optional Bluetooth music streaming (bypasses cassette player but I no longer use cassettes). I prefer that my car look stock rather than have a flashy add-on stereo.

Other options:
-Buy unit off of eBay and pray it works but radio code will change
-Buy a compatible encoder for like $15 and see if I can replace damaged encoder on the board.
-Buy a aftermarket unit that's compatible with Bose amp and steering wheel controls
