I have searched, but haven't found the exact answer and I'd rather not buy the wrong cord...

My car has the OEM iPod connecter in the glove box. Cable has gotten frayed at the end, and now cuts out randomly.

The cable is the one with the white end and ethernet on the other side--picture copied.

My questions are this: 1) what is the part number for just this cord and 2) does the new cord with black end that also charges the iPhone (part number B6 782 4532) work for a 2007 W211?

Thanks.
