CD Changer again

What is the differnece between 1j5 035 111a, and 1j5 057 111a???

Does anyone know???

I have the first one, and a guy I know has been told he needs the other one, have found the part number on a VW Brochure, and it looks like its for the Bora???

Am I not mistaked, but the Bora and the Octavia are very similar cars, and thought that most things like radio and CD Changer were the same.

He is asking for the one with a 10 pin plug!!!

Mine is a 12 pin plug, but with only 10 pins in it, so to me, would be classed as the 10 pin.

Hopefully someone could inform me where im going wrong, or if i am indeed right??

Cheers,

Chris
