Forgive me if this is posted in the wrong area, but I'm new to the forum.
I have a 2012 Phaeton 3.0Tdi with an RNS810 infotainment system.
Nice though it is, I am struggling to understand whether I have the most up to date firmware, how to update if (if I don't) and how to upload personal POIs to the map (as I have seen possible on the RNS510)

I bought the latest V15 map disc from VW, but the main dealer was pretty unhelpful to be honest, and wouldn't enter into discussions regarding firmware updates.

Any help would be appreciated.
