92 bonneville tape to cd change out

i have a 92 bonneville w/ tape, eq radio in it i am likeing to change it to cd but have had a hard time finding one to fit.i tried one from a 94 grand prix se but it would not plug in right, i have steering wheel controls also that i would like to keep, pioneer makes on to fit but then i would have to use the pioneer remote, so if any one knows the years that would work or a resource that i could get one to interchange ,i tried the forsale section in here and come up with nothing. so if anyone has feedback for this issue then that would be cool.
