my 96 2 dr tahoe came with a stock radio / tape player with a separate cd player underneath. the 97 tahoe's and up (maybe the same for silverados and subs) have radios with a built in cd player. i can't afford a new after market cd player and i have read on some forums (maybe this one as well) that the later radio / cd combo may or may not work on the 96's. i have tried many radio / cd combos (using the stock plugs) and the radio portion works but the cd players do not. anyone have experience or good luck doing this or is it just not possible.
