Sansa Express european model. what firmware?

Living in Italy I have a Sansa Express without the FM radio, and also I have seen that I do not have any possibility in the firmware to switch between the working mode of the player connecting into a PC.

What would it happen if I load the latest firmware?

  • destroy everyting, not working anymore

  • new firmware with radio and working

  • new firmware without radio and working

any idea???
