behave as it should, it can be fixed by resetting or restarting your

I had the same problem and solved by accident:
use Tomtom Home>>Operate my device, beneth the simulated screen there is an option to "set current position", click it and manage to configure voice selection, choose any and go back.
unplug your tomtom and it should be working again
Hi Juanin, just posted this for a near identical problem with a Tomtom 700;
When you get this kind of problem with a Tomtom device always start with the memory card, so:
1: remove the card, clean the contacts and if you have an air duster (available from any good hardware store/electronics store) clean the card slot, then reinsert it.
2: make sure the card is readable on your PC to ensure it doesn't have a problem. if this doesn't help then
3: format the card and reinstall the maps & software on to it.
4: make sure the card is reinserted correctly.
Next is the battery, leave the device switched on until the battery runs out, switch it on again and it should stay on for a moment then switch its self back off, repeat this until it will not switch on anymore and then charge it for at-least 16 hours before trying it again, this will re-calibrate the battery.
Diagnosing a problem is a process and this is just the start of it, don't be disheartened if this doesn't help, just message back with the results.
