Niether the '01 X5 or the VetteVert have a changer...I toyed with the idea of having
one installed/retro'd, but since I listen to my home made compilations or, a lot of
classical music, the car changer thing has come to not matter that much to me.
(Bach's Partitas for Keyboard, etc., don't come across too well in "shuffle mode", lol!)

I do like our house changer for casual background listening or for when
we have company and I just load up 5 discs and let it shuffle/rip...

AznMPower: get that changer if you like it.
