I have a 2017 sg need to update navigation what a pain anybody done this?

 

Buy a flash drive, insert flash drive into your home computer, go to hd website, find update on website, download update onto flash drive, unplug flash drive from computer, plug it into bike connector inside the right-side cubby hole of front fairing. Turn bike to ignition or accessories, and it should do the rest​​​​​​.
