Spartz31

I checked the sticky on this to see if any thing pertained and didnt find my issue. I just bought a few months ago and the blu tooth kind of worked then quit working. I disconnected the battery and it started working again. Once again, slowly loose features. Now it connects but does nothing, then when I get a call I brings through the radio but I have no audio. I cant find any updates online to see if there is a resolution. Any advise on how to make this system work.
Btw I am using a galaxy s8 phone
Thanks in advance
