Odd CD changer part # and info



Looking at buying a OEM changer off the net. However, this one has a strange part number.
Instead of being MH3510, MH3511 or MH3512, the part # is
B6 782 40 60.
Also, very oddly the unit is missing the manufacturing date. Any idea whether this CD changer might be dodgy? If it's not, any idea if it plays mp3 files?
I'm attaching a picture of the changer in question, along with a picture of one of my old (broken) changers that has the normal part sticker on it.
Any clarifications greatly appreciated!
Thanks
Murray
