I finally determined that if I deleted the TuneIn app from my phone and reinstall it using an old version of the app,
then the app works again.
This is just another example of the failed attempt to integrate phone apps into the cabin entertainment by Cheverolet.
Not only does my TuneIn not work right but now after changing to a new Samsung S8 none of the apps work right.
Also there was the other debacle when Chevy released the door chime recall software fix it broke the BringGo app so that speed warnings no longer work.
I wish Chevy would just provide an upgrade path to Android Auto for my Spark. It's still my main commuter car.
But no more Chevys for me. My wife changed to a Chrysler Town and Country and our daughter changed from the Sonic to Mazda. When my Spark finally dies it won't be Chevy I go shopping for.
