radar|lidar detector cell muting - is it possible? Options

[xkillerx]

i've got a whistler euro948 radar/lidar detector which does a great job, but the sound alert is way too quiet if the music is turned up loud (oh yes, i like my music high quality and high volume). so i either have to drive slow with my music loud or drive fast with music quiet so i can hear the detector in case the cops are targeting me. so the question is:

is there any way to make a cell-muting bridge for a detector (i think ALL lidar jammers have this option factory ready) so it would mute my audio system when it's detecting something?

the head unit has a cell mute feature of course, that's not the issue - the issue is that the detector doesnt have the interface. point being does anybody know how the cell muting interface works at all, aka what kind of signal does it send to the head unit? because then maybe i could pick apart the detector and hotwire the speaker wire to send some kind of signal to the head unit too (to make the music stfu). but unfortunately i never had a real car phone in my hands so have no idea what's it all about.
