If you have not already managed to sort this out I can offer some help.
I will send you the link to the person that helped me with my mapping. He is legit and it does work. No issues - I just did the last 2018 December update on my NAV system.
You can contact him via email message and take it from there. First watch his video and you'll see for yourself.
Note that at the time it was for the SKYACTIV models only.
He'll need some info from you, but will reply fast. It took me about 20mins to do everything and have the navigation setup.
