Device rebooting and losing info

Hi All,

I am having some issues with my Go Live device..and was after some advice/suggestions.

It all works, but once a day or sometimes more often, it reboots itself and i lose all my favourites, home etc (Mapsettings.cfg). I have tried running on a micro sd card and also on the device only without the card but the same thing happens any suggestions?

Thanks in advance
