Ok, I may be on to something. It made no sense to me that I could listen on my headphones all day with no issues and yet 2 Car systems are having the same issue. I brought the Bluegate system in the house and set it up on a pair of portable speakers................Worked like a champ
Then it dawned on me I was streaming over my house wireless, so I turned Wi-Fi off and boom quality and audio level dropped right off immediately.
So now I'm thinking maybe its the marvelous coverage that ATT provides and the quality level of Google Play adjusting to the throughput of my LTE or not signal. Guess I need to download some music to the phone and test it out.
