I have a 96 Monte Z34 and have recently put a new cd deck into it......The 96 Monte Z34 came with controls on the steering wheel that would control the cd player volume and tracks. Now that i ahve the new cd player, the controls on the cd player don't work.....and the guy at futureshop who installed it tells me those controls will only work with the stock cd player, and there is nothing I can do. Does anyone know if this is true? It seems hard to believe that those controls will just be inactive for the duration of the cars life, just because I installed a new cd player.
Any info will help, thanks a lot.

You need to look for a PAC steering wheel interface kit. It's basically a universal remote that you "teach" the functions of your steering wheel controls. I put one in my 99 Grand Prix and loved it.
