used in Samsung sgh-i780 and it worked immidiately with very detailed map , also the address search functionality started working(however,With India maps address search rarely is of any use) . Guys, I must tell you that if you are connected to ur laptop from ur phone in the USB mode, the Garmin MXT shall not work at the smae time. This is because the laptop is using the memory card and during that period card id is not available to the Garmin software (It would display you to purchase).
