RCD510 part numbers

[msond]

Hello,

I am looking to replace my RCD310 (with dab) with a RCD510 (with dab) in a 2009 mk 6 golf. Whilst looking on ebay, I have come across units with slightly different part numbers.

The first part is the same - 5k0 035 190, but they have different letters at the end (e.g. A, B, G). Tried to see what they difference may be, but not found anything. Wondering if anyone can help.

Also, has the unit been updated over time? I am better off getting the newest one possible?

I want to ensure I buy one with dab, still use the bluetooth and parking sensors.

Thanks

as far as I know the software has never been updated but buying the most up to date unit will ensure you have the latest software.
