can anyone tell me the compatible cd changer part numbers for my W164 (with single disc comand) .

I have searched the usual places , but keep getting conflicting numbers,
A211 870 38 89
A211 870 61 89

these 2 keep cropping up, and when I search for them it appears they were also fitted to other models. Is this correct, and if I find one for sale from another model range ,and buy the glove box fitting kit, will I be sorted??

Hope someone can help me out.

Thanks ,

Iain
