I thought I should post this in case someone has the same issues?
Symptom 1. No sound at all from unit. But then comes back and everything works.
After much digging around and contact with Zenec this turned out to be the reversing signal from the gear lever rather than anything at all wrong with the head, Pulling the unit out and unplugging both 'Reverse' connectors restored the sound. I had it fixed at an upcoming service. I think they changed a switch. Oddly, it did not force the camera view on which it normally does when selecting reverse.
Symptom 2. No sound from sat-nag although the 'speed limit is xxx' nag still works as does the radio and other media.
Go into settings and turn 'use voice navigation (or is it guidance?)' back on. I have yet to find out how it gets turned off, but it's always at the start of a new journey, usually one that has a complex exit route and nowhere to stop to correct it. A right PITA!
This might be of help to others.
