Help with MMI version in my CPO SQ5
 

I just got a new-to-me 2015 SQ5 from my local audi dealer. I was hoping they would update the system to the latest versions of the maps and firmware for the MMI/Nav system. Can anyone tell me if I have the latest versions of either?

From my research in different places it appears to me that I have the as shipped MMI version but I can't tell if theres an available update for it. The large Wikipedia tables offer version numbers but I don't know which one goes to which MMI and which ones are the newest updates.

I'm pretty sure there is an available Map update but I know I would have to pay for that. Mostly I'd like to update the MMI to the latest version if it has any bug fixes/performance-usability improvements/added features.
