Please can anyone help me,i haven't used my smart 25 for a while but when ive I tried to use it all I get it the dark screen with tomtom and circle with hands on. ive tried doing reset but nothing changes I just get the drum roll over and over again no white writing. also when trying to do reset/updates no computer is recognising my device. what can I do im not very good at tech stuff so if anyone can help a dummy like me id be very grateful
