HW and SW for fixing volume problem on audi radios concert and chorus made by blaupunkt

Software and hardware to fix volume problem on audi concert1/chorus1 units made by blaupunkt. More about this problem in this wiki page which is copy from here.

These are 100% compatible, manufactured by Blaupunkt:

Maybe for these, drop me a message with pictures of radio from outside and inside, and I can check if your radio is compatible with this module:

Audio Concert made by Panasonic/Matsushita (8L0 035 186A, possible other codes ).This radio from this manufacturer did not have problems with volume (if it has, the problem is in volume rotary encoder)
