FYI, I was checking out the Jeep website yesterday, and under the owners tab, I noticed the Uconnect Software Update link... https://www.driveuconnect.com/software-update/?origin=j
So I went there and put in my VIN, and it showed an update for my vehicle...
Your 2016 equipped with the system qualifies for the following software update:
Update 1: UCONNECT® 8.4AN_RA4_16.33.29_MY16
Service Bulletin ID: 08-057-16_REV.A
Release Date: 2016-09-06
It provided a download link, so I downloaded the file, extracted it to a USB drive and followed the instructions on the provided PDF to update the vehicle. Took about 20 minutes of sitting with it running, but it worked just fine...and cost nothing.
As you can see, it was released on Sept 6th.
