According to the MapnSoft rep I spoke to this AM (6/30/15), that NAM version is their V8.5 version maps which came out in January 2015. The soon to be released updated v9 version is still delayed due to software bugs but should be out soon. However, I was told earlier this month that it would be out before the end of this month, so just keep checking their website.
I have the same NAM version in my 2015 Genesis Ultimate that I bought at the beginning of this month, so I thought my maps were way out of date since I knew there was a v8.0 and v8.5 update released. Why the NAM and MapNSoft versions don't match is really stupid and confusing!
However, depending on when you bought your car and how much noise you want to make with Hyundai and the dealer, you might be able to get a coupon from Hyundai to defer the upgrade cost. As I mentioned, I thought my brand new Genesis' maps were way out of date and no one at the dealer or Hyundai could tell me the NAM version meant I had MapnSoft v8.5, so I raised a stink about buying a new car with way outdated GPS maps. Hyundai coordinated with the dealer (I don't know how that went), but Hyundai sent me a $100 and a $200 coupon to use to update my map software when it's released. From what I read in some other forum threads, Hyundai sent some new Genesis owners a $100 coupon, so I guess they sent me an extra $200 coupon. As they say, the squeaky
wheel gets the grease...
The MapnSoft rep also told me the maps on navigation systems that use SD cards get updated twice a year and systems that use USB sticks get updated once a year. However, I didn't ask which years/models/systems he was talking about. But, at $219 for an update, I won't be updating that often. However on a side note, I got used to getting quarterly Garmin updates for my Chrysler 300S uconnect GPS via the lifetime updates obtained from a Nuvi GPS that I paid $130 for.
