Standard functionality apparently, as I see a lot of discussions on many different forums about this; Bolero (I think - the basic, non-high-end audio, non-satnav) infotainment in my 2020 (last of the MkIII) Octavia combi Scout, the media player "ducks" the audio if Android Auto/ Google Maps navigation issues an instruction or an alert. (I often have it set to alerts only, so it doesn't happen as often, but at least here in Spain where Google Maps _does_ know where the fixed speed cameras are, alerts happen with some frequency). 

All of the threads I've seen on various forums say that it's actually the audio player app which is choosing to "duck" its own audio underneath the higher-priority navigation direction/alert sound, and that if it would be possible at all to disable that (so that the infotainment player's audio volume does NOT go down) then it would have to be a setting in the player, not in Android Auto/ Google Maps navigation.

So, is there a way to configure the (I think) Bolero built-in media player (e.g. playing an audiobook off of the inserts SD card) to NOT lower/duck its audio volume when Android Auto/Google Maps navigation has something to say? 

thanks,

 

Hm. Nobody? Beuller? Beuller? 

So, a different angle on this - if I can't stop the car's built-in player from reducing audio, can I at least get it to pause playback at that moment and STAY paused? I noticed (I just completed another of my cross-continent Spain-to-Germany drives) that if a phone call comes in, the car's built-in audio play either doesn't pause at all, or it automatically resumes (at ducked volume), resulting in unknowable amounts of missed audio playback...
