Thanks to the info on this thread, I can add my name to the list of successful upgrades.
Found a used 2017 screen and receiver assembly off a 2017 Touring and installed it on my wife's 16 Touring.
Finding the correct unit was the most difficult part of all.
I searched LKQ and Car-Part websites for hours until I figured out what to look for.
99% of the parts they listed under 2017/18 Pilots were actually the 2016 p/n.
LKQ was the easiest to navigate, I just scrolled thru each listing and decoded the VIN that they show as the source for that part.
Once I found the exact unit, I called LKQ and asked them to send me photos showing all angles, including the label with the p/n and serial no.
I then logged onto Honda's site, entered the VIN and serial number to make sure the two were a match before committing to purchase.
Got the package yesterday and installed it in less than an hour.
The sixth unlock code on the email Honda sent me did the trick and everything is working perfectly. My wife is happy now.
Thanks again to all those who contributed to this thread.
