Audio warnings approaching Speed Cameras & Risk Areas

I am a newbie and have a Citroen Grand C4 Picasso 2.0 2015 with the 7” touchscreen, I have downloaded the CITROËN RISK AREAS & the SPEED CAMERA DATABASE successfully (pinpoints sites of fixed speed cameras). I can see the new icons on the maps but cant get the audio warnings which according to the “how to download the additional software installation notes” are supposed to be available to notify me that I am approaching the camera etc. (I am in the UK). Citroen dealer says phone “Here” customer service who provided the software but they say contact the Citroen dealer !!!!!

I have played with numerous settings in the 7’ display for audio & alerts going back and forward past speed camera but to no avail – any ideas please? Thanks

One other request - how do I get the display to let me know estimated time of arrival, distance etc?
