I see some people talk about the upgrade from the x930bt to the x940bt what does this upgrade do? Does it give the user the new x940bt homescreen? anyway to tell from the software side which unit you are running if this upgrade has already been done? I am not sure what this upgrade would do the only diffrence I can see between the x930bt and x940bt is the GUI?

 

Any info would help.

 

Thank you!
