Question re: adding cassette player

I need some help guys.........

My '97 Trans Am has a Monsoon system w/ CD. I want to add a cassette player as well... I know it sounds crazy, but I have hundreds of cassettes I still listen to.

However, I know nothing about car audio. Is there any way to add this without buying a whole new stereo?

Thanks in advance,
Jennifer

ok, not to sound like a smart arsh, but why not download the songs and burn on a CD-R.? Another way would be to get a new HU that has both cd and tape player
