[Mattd938]

Just bought a RNS 510 off ebay to fit in my FL FR but not sure which version it is, hoping someone can shed some light?

Part number is 5P0 035 680 A - does this mean its a version A??

Manufactured 11.01.16

Hardware H10
SW 2680

Its supposed to be a LED unit and it has the star button in the top right corner.

its also got a number underneath the barcode that ends in a P

Anyone have some info please?
