Automobile cd player aux. port installation.

I drive a 1999 Chevy Tracker, same as the Vitara.  I'd like to play my mp3 through the OE cd player.  Any hints in installing an aux port as there isn't one on this older player?

(made up number) 95+% of vehicles simply don't have an aux port. It's a very recent (last 5-ish years) and generally adding one means swapping the deck. I'm in the same boat right now.
Yes, but it SHOULD be possible to hack an Aux port in it ?

If you can figure out where to inject a signal to the amp circuit while the deck thinks IT is sending radio could be done.
