Purchased the CD43 from the group buy thread. Works great ! Now I lust for a CD Changer. Understand it has to be a "I" bus (or something like that). What is the best Alpine CD changer that is compatible with the CD43? Good place, pricewise to buy it? This is for a 1989 535i so will need to run new cable from CD43 back to the new unit.

TIA

Jim
