Is there a way/instruction of how to put an input into a '99 Camaro AM/FM CD radio for an IPod-like device?

You need an Aux input or IPOD adapter

Thanks Kevin. That's what we were looking for.

I have a PIE GM-auxv12 in my 2004 Impala, works great, love just listening to songs with the IPOD instead of all the TALK on the radio. I have a converted Radio with IPOD for my 69 to go in soon too! Luck.
