Hi, I own Garmin Zumo 595lm and Cardo PT Bold.
When nav gives commands intercom volume gets very low and i can't hear what other people are saying.

Problem is that Zumo is sending commands through HFP and not A2DP. If HFP is disabled in bluetooth settings there will be no nav commands.
My idea is to force nav commands through A2DP . this would fix everything.

I don't know much about modding so that's my question, Is it doable or just a pipe dream ?
