Hi all, thx for your input. I made a little trip this afternoon and tried your suggestion. Unfortunately this is not working in my car (2017 GTS). If I press "MAP" while playing music or radio and the voice comes up I can not change her volume. Maybe the Dutch version of PCM 4.0 has other software than the ones in the UK.
But I found a workaround;
1. independent of under nav guidance or playing media/radio.
2. Push NAV>Option and choose "Set navigation volume (I am not sure it is in this setting in English, but you know what I mean).
3. Set the volume to Max (11 in my case) or lower if you want.
4. In the same screen touch the loudspeaker icon under the volume setting to mute the volume. The setting of 11 (in my case) disappears, but don't worry
.
5. Leave this screen.
6. Start navigation to your desired destination.
7. As expected, no navigation instructions are to be heard.
8. Push the "Map"button.
9. Result> The voice comes up with the actual instruction at my first set level of 11.
This will work for me
. In difficult route-conditions I will just push the Map button for spoken instructions. The rest of the time I can enjoy my PSE
.
BTW Simon: I just got a crush on your T. Magnificent car!!
