sounds like the same prob as my one.
Did u drop it or did it take a decent hit?
Most prob the hard drive has died, they use 1.8inch drive the same as in ipods.
It is repairable if u can source a new HDD and have all your files and maps backed up.
the software is available from tom tom web page, but remember they will charge for the map.
