Stuck authenticating.... I had this problem. 2014 CVO Limited which I have updated maps once last winter....
First what I had done- uploaded and installed the radio update. Then I tried the Navi Sync update but got some - non-readable files messages. Tried a few different ways to download it on to the thumbdrive, including opening files and downloading only the largest "SWDL" file. Still stuck. 20 minutes and nothing.
SO now for the fix-
Checked my files in bike.
Starting with HOME: Setup (upper right): System Info: Navigation.
Inside I found:
Navsoftware- 9.10.14.659374
MapDatabase NACVO-MY2016
Dealer Database DLR-2015-Q1
Went back to my computer- still the NAVISYNC on the desktop I had downloaded from Harley,
Running Windows 10,
Formatted Thumbdrive (8g) so it was blank,
right click on NAVISYNC and selected Extract All
The pop up box named a folder but I browsed and picked the thumbdrive (E for me)
When it loaded I got two items in the thumbdrive. Navisync and Swdl
Back out to bike. Set on ACCESSORY, waited for radio power up. Accepted the death statement. Radio plays, Hit Navigation and got "Navigation not ready message, waited it out. When the screen came up I inserted thumbdrive, flash of something, checked the files and authenticated in less than 30 seconds and updated after I hit YES.
When done I checked and all the data bases the same except - Dealer database is now DLR-2016-Q3.
