no bro, this has nothing to do with the upgradation of the website i was able to perform each and every step includes some updates on the navigation core files in the mem card.
the query spinning in my mind is that how come the system recognizes the licensed mem card and non licensed mem card. i have 2 identical mem cards contains same files but system recognises the original one and rejected the copied one, i received an error message that MAPs cant load with this licensed key. so i am just curious to understand the mechanism how system authenticate the originality of the mem card.
