RNS 315 Mic cable for 2K0035279C

[MattBW]

Now I have enabled the BT, I would love to install a Mic into my RNS 315 to get the full capability.

However after extensive searches, it seems the mic I have (and that are sold online) are related to a different part number RNS 315. Mine is 2K0035279C.

Anyone know if the Mics are the same or if I need something else? I don't want to take the dash apart only to find it doesn't fit. If a jobs worth doing its worth doing only once
