my garmin 300 nuvi no sound ?

If you have recently downloaded new software, from main menu go to settings, local or locale, then touch the name of the voice you require from the list. OK and then go back to map. If no voice was selected no voices would have been heard. This was what happened to me after installing new maps/software. Hope this helps.
