I am also using USB connection for AndroidAuto.
I was hopeful more experienced car audio folks might have a workaround short of playing the test tones via AndroidAuto since I have teenagers that like to crank their music and I fear they would destroy my sub.
Sounds like what I'm hearing is there is no workaround.
