Pryater ,
You have made me look like a superstar.
I can confirm 100% this works. I used the 2017 files.
I used a combination of files ( hint - think torrents ) . Total is over 8gigs.
Last night it seemed to be stuck on a loading screen, I guess I didn't give it long enough.
Thus morning we left to NYC from Ottawa and my nav is working like a charm.
Pryater , thank you for your quick replies and help. I could not have done this without this thread !!!
Ron
