Android Auto audio volume

[kodiakdenali]

I couldn't find anything relevant on search. I notice that at times when using android auto the volume of the audio is very low. even with the bose system I can turn the volume up to 100% and still not clearly hear the audio with the windows down at interstate speeds. granted its quite loud under those circumstances, but the bose should have plenty of power to overcome the wind noise. this volume issue seems to happen quite often, but not always. when its not acting up I probably can't get the volume level beyond 25-30% before its too loud. when auto is connected the volume on the phone is locked to the volume of the head unit, so there's no additional adjustment on the phone side. anyone else experience this?
