Tom tom gps speakers not working.

Question

I have a tom tom gps model One XL and it's been working well until two days ago when I noticed there was no voice directions.
I checked and followed the manual step by step and could not get the voice to work.
Yesterday I stopped went to Best Buy and the technician also followed all the setup instructions and said it could be the spaekers.
Other then the speakers everything works very fine.
Help,thanks K.([e-mail])
