Default [Q] Some problems with Tom-Tec ATF3416 2.2 7 inch tablet

Hello,

I have TomTec ATF3416 2.2 7 inch tablet and I came across with some problems. When I try to turn on the tablet, then monitor show me TomTec logotype and thats all. When I put in MMC card (with firmware update) - nothing happens, when I plug in USB cable to PC, PC don't see tablet. So... What should I do ? Please help me. By the way sorry for my English.

Have a nice day.
