Dvd-Gps 7" ZENEC MOD:ZE-NC510

[GHSIAO]

I bought a DVD with GPS screen, 7 of the mark ZENEC mod ZE-NC510 [Only Registered Users Can See Links] Trying to put the map of Brazil, formatted the flash ROM on the Windows CE 4.2, then lost the folder shell with the three files. I save the folder shell, but now it does not GPS and more into the Windows CE pra undo the error.

SOMEONE CAN HELP ME?
