if i put an aftermarket deck in my CL will the controls on the steering wheel still work to change the volume,ect. ???

 

no the steering wheel controls will not work- i installed a sony aftermarket radio in a while ago, it was nice- but the annoying part was not having those steering wheel controls.
but i do believe alpine makes something that allows you to hook up your stock steering wheel controls to an aftermarket radio..

 

PAC makes a programmable adapter that allows you to interface with the stock steering wheel controls.......cost is around $30 if i remember right........hope that helps u
