"The update 1/25 you are speaking about is the buzz app update. The Dec 20 update is version of the firmware and is correct. Remember, everything on the buzz (app and firmware) automatically updates itself, so you will always have the latest updates on the unit."...!
"Get back to Settings menu, seen on the main Buzz screen.
Enter here and you will have some setup options.
-Server setup
-WiFi
-LAN
-Date & Time
-Display
-Language
-Update
-More
In Display is where you can set screen resolution (1080p 720p and etc...).
Can also turn High Dynamic Range (HDR) on or off or auto.
In Upgrade is where you can set the buzz firmware as Auto Update or Manual Update Now.
Depending on how you have update set (Auto or Manual) the 'Upgrade Settings' will give different setting options.
With it set as Auto, we will see in this Upgrade settings menu an option to check in intervals. It is defaulted at 1 hour intervals."
Just guessing that, Update and Upgrade are the same thing...!
