My pid has just stopped giving me voice directions and speed warnings. The music from the pid is still fine so there is a sound link.

In the past I found a menu to control voice volume but it seems to have vanished. Any advice on how to get sound navigation back ?

Do a reset on the PID. Turn completely off. When turning back on, press on the screen until it starts. The PID does this occasionally. It will lose some settings,but not all information. Check back posts there are a few.

Common issue on the unit, I find it happens when you hit mute when navigating and it gets to the destination and you exit without unmuting, when you go back in, it doesn't unmute and as above it needs resetting, just need to remember to make sure the volume isn't muted before you arrive at the destination
