Android Auto issues

[Alvin2504]

I have 2 queries

I have Poweramp installed on my car android unit. When i receive a phone call the music does not pause until i make the call but gets louder and can hear both music and call at the same time. I tried playing around with several settings but no sucess

 

When playing a song on main screen and switching to library the list does not show from the playing song but shows from the begining of the list. Even when moving to the next song the list remains on the first song

 

Thanks
