well in my 02 trans am i just realized came with a 12 cd changer, unfortunatly it didnt come with the cartrage to hold the cd's... so where can i get that replacement part?

 

A Pioneer JD T1212 fits the stock Monsoon 12 disc changer. They're available from www.crutchfield.com for $34.99 or you can check eBay for a cheaper stock cartridge or Pioneer cartridge.

I bought the Pioneer to have as a 2nd cartridge and can vouch that it works.

 

Here's a direct link:

It appears they have a returned one for only $24.95 right now too...
