I have read all the usual posts but I'm lost. At first it seemed it is impossible to have the zumo give directions without pausing the music, but later I read about people who managed to get it working.

I have a sena 20s with 1.7.6 a Huawei mate 10 pro and a Garmin zumo 395lm. The Garmin is connected to the sena and the Huawei is connected to the sena as well(it does not play music when connected via the zumo to the sena). The phone is paired as the first phone. I can play music and make calls. The zumo is paired in GPS pairing(green light, etc.) When I play music(fm or via the phone) and the Garmin gives directions, it fully cuts out the music. It doesn't pause, but I can't hear it anymore. It also cuts out the intercom. I have audio multitasking enabled. The sound is pretty bad so it has to be mono, so the pairing should be as GPS. It doesn't matter if I uncheck "media sound" on the Garmin. I already cleared the Bluetooth pairing list and did a factory reset on both devices.

When I use the button sound on the zumo and I play music via my phone on the sena and I press a button, there is no real sound. Just some crackling and static noise. When I don't play music, I do hear normal button sounds.

Is It possible, and if so how is it possible, to have my GPS give directions without fully cutting out the music from my phone or FM on the sena?
