Hey there, I'm brand spanking new to the forum. I just picked up a 2002 S2000 with 26000 miles on it and want to ad a CD Changer to the stock head unit. I already looked throught the FAQ's and it didn't state anyting about the CD Changer. I wanted to add one to the stock head unit but also want it to play mp3's so I was wondering which CD Changers out there I can use with the stock deck. I know in 95 I was able to use alpine with my stock deck and all I needed to do was buy and extra cord. Thanks for the help.
