Ref the no volume etc, if you take the back off the unit, the speaker plug is accessible. It may have come loose.

my navman f20 has stopped talking when it is un use, i tried the mute and the volume but these seemed to be fine, does any1 have any ideas. I phoned the helpline but they wasn't bothered as it is out of guarantee, all they wanted to do was to tell me to buy another.
