All RCD 510 fitted in Aus VW's are made by Bosch assembled in Portugal under licence. On the top of each unit is a label showing the wire allocations etc. on this label is also three 4 digit numbers called FDxxxx (manufacture date) HWxxxx (hardware version) and SWxxxx (software version)

The important one is FD where the first 2 digits are the week number and the second 2 are the year for example there was a unit on ebay out of MY13 Amarok that had an FD 0912 which means it was made in march this year much like tyre manufacturers use.
There are also a number of versions of RCD 510 made by Delphi in China. These are for VW's assembled in China for the local market although I understand some are used in VW's for the North American market as these units do not support RDS. They are supposed to be of similar standard and quality to the Bosch unit but I have never seen one physically to confirm. I am given to understand None of the Delphi units support the phone book function

The easiest way to ID the Delphi unit, is there is only ONE large button on either side of the CD slot where as the Bosch has TWO buttons on either side.

My advice to any new vw owner wanting to replace their RCD 310 is get a Bosch RCD 510 no more than a year old otherwise the current factory fitted 9w7 unit will not work properly as we are finding out.
