christmas help

here is the deal. my fiances car was broken into and stole his cd player out of his ford escort, but they took the ac piece with it... so i bought the ac piece that holds the cd player...

here is my question, Do you have to buy a certain cd player for different modle cars???

or is it all the same.

if you have a cd player for less than 150 that's not a piece of crap :) please let me know
