where do i get repair CD

normally i post in the Sl500 section as i have a 99 sl500 BUT... sleepwalker, all knowing oracle- you have in the past posted replies showing really great diagrams (routing of fiber optic lines for example). I need to know where to get a CD which has similar/identical type information on it for a 2000 430 CLK Cabriolet. As my other posts may show, i prefer to do all work on my vehicle myself (and no bs intented- the help i got in the past on this forum saved me ALOT of problems).
thanks, george

there's a part number on it.

use that number if you want to order.

if you want to know what car model uses the same cd changer, tell me the part number or your vin so i can find it.
