I am just about to embark on the OEM Bleutooth retrofit on my 2003 A4 to my already installed (by me) RNS-e.

I still need to get the Bluetooth Mike from Audi Main dealer, Part Number 8L1 862 373A which retails at about 50 odd + VAT.

I note that VW & Skoda (hmm)...use a similar Bluetooth Microphone part Number 3B0 035 711B

Are the VW & Audi microphones I have detailed above essentially the same part ?

I would appreciate anyone letting me know.....cos I am an sure a skoda dealer will charge less for it....he says niavely !
