Inifinity 6-CD changer part number and compatibility.
 

I need a changer for my 2005 GTS, and I have found two different part numbers: MR587252 (roughly $90 and black) and MN141260 (around $240 and silver).

Can I use either one? I'd rather spend less money if I can, but does anyone know if I can use either one, or I just need to buy the correct one. Thanx!
