There is no way to see a maps version for an owner. It has been suggested a SC can via service menus. Only way as suggested earlier in this thread is for an owner to perhaps find something that changed with the latest edition, someone clearly document what that is, and people can then look for that location on their MS to see which version perhaps they have. Yes it's convoluted at best. Tesla needs to build in the owner ability to display maps version, no different than firmware version can be seen via the 17" T.
