You should post this question in the discussion and user support sub forum.

"Formating" is all about flashing your device with the correct firmware or commonly known as "ROM". In any case you will need to know the type of electronic board inside the gps if it is MTK, YF, Mesada, Apical and etc., then you also need to have the firmware for that paticular type of board before you can flash the device.
