Ok, I think I misunderstood something somewhere...the reason is that I went into :
Entered my vin number and the message I got on my screen is :
There are no updates available for you 2014 Jeep Grand Cherokee Limited X4X4 equipped with the Uconnect 8.4N AM/FM/BT/NAV radio
So after reading that...I believe my system is current and there are no newer updates, mine is international version (I'm overseas in Uruguay).
So...I dont thnink now I need to download or update files, am I correct ?..
