Hello:
The software version doesn't seem to be the problem, It's the 5150, the same that I have in my S8 '08.
Is the disk from the seller an original or a copy?
Anyway, you can burn your own copy of the latest maps available (MMI 2G 2017)
-Go to this
site and see the links where you can get the maps.
-Burn the DVD (good quality, Verbatim if it's possible) at the lowest speed that your DVD burner can do.
-Insert the DVD into the navigation reader and let's go.
Worked in my case at the first attempt!
Cheers
