It sounds like you do not have the right radio or it is not programmed right. There are two different Bose models, one is the standard Bose like used in a Silverado or lower end GMC and the other is the upgraded Centerpoint unit that uses a different Bose amp andwiring and is programmed different. This would explain your no volume condition and the problem with the equalizer. I believe that the radio head units are the same physically but are programmed differently. The wiring and amps are different between the units. If you have a speaker in the center of your dash, you have the upgraded unit. If you do not have the center speaker, you have the standard unit. The head unit must be programmed to the type of amp and wiring you have in your truck. I don't know if a dealer can program the radio from one type to the other but Greg at CPS Audio can. Do a search on this forum and you can find his telephone number. I had him do mine when my dealer said it couldn't be done.

 

Hope this helps.
