i just recently purchased a 94 corsica for my winter beater. It came with a pioneer tape deck and a 12 disk cd changer in the trunk. the only thing is the people i bought it from did not know how to operate any of it for some reason. THey said everything worked when their son used the car. I can get the deck into multi-cd mode and change cd's but i dont know how to play them, and one have any idea what button to hit on deck or remote to play cd

 

Look for a SOURCE button on the radio. May be on lower right hand corner. Keep pushing until the changer shows up on the radio display. You could check Pioneer's site to see if the manual for them is online.
