I had to replace the BOSE head unit in my 2002 I35 for popping and cracking noises and purchased the entire setup from Ebay. I now have the questionable head unit, the working AC/Heat controls and the brackets.

Is there any value or should I just trash it all?

 

AC/hear controls and brackets might have some value. Throw them up in the for sale forum. Someone may be selling their car and looking for something to teplace their more valuable aftermarket setup.

 

Actually you are probably better off selling it on Ebay. Over there you could sell the set up for $130 to $150 + shipping here on the org you'll be lucky to get $75 and that is including shipping.
