Navman pin 300 pocket pc

[gt4st205]

Hi
I have a pin 300 navman, my girlfriend stupidly not knowing.
Turned it of by the power switch on the back which reset factory defaults.
I thought the smart st pro navman would have retained on the storage card but it didnt.
I havent got the installation cd with me,
Does anyone know to reinstall the sat nav back on to my pocket pc and where to get the files from.
Any help is extremly appreciated
cheers
