Crazy volume changes

[Mikedfw]

Ever since the over the air update or maybe the recall, dont remember, whenever I'm streaming music from phone via bluetooth or usb connection, my truck has no decided it will change the volume settings on my phone each time I start the car. 

 

Anyone seen this?  It will also not always let me make adjustments to the volume on my phone when it has changed it. This is a problem because sometimes I'll get in, it will turn down the volume all the way on my phone so I have to turn the truck volume way up, next time I get in, ita reverted to a higher volume and blasts my ear drums out.

Most common issue with Iphones was the truck bluetooth connection would lower the phone volume down when connected BUT it would NOT raise the phone volume back up when it disconnected from bluetooth, that was resolved for me with the latest over the air 13 min download that everyone should have gotten about a week ago?

This is android and it is much more random. It doesn't change the media volume on my phone when it is disconnected, only while going through the trucks speakers be it via bluetooth or plugged in. Its just every time I start the vehicle its different. Sometimes it will be the same volume as previous time, others it will lower it on my phones bluetooth or gmc media setting while in the car.  

 

Sometimes it will lower it and if I turn on navigation once the voice prompt speaks when the music comes back on it will crank it back up again.

 

Its really random seeming and it is incredibly annoying. It didnt do this until after I got the last over the air update.
