I've used Xiialive with my HTC One M7 and worked perfectly with my car bluetooth radio: xiialive started when I set the source of the car's multimedia unit to Bluetooth. It even worked with my Samsung S6 for a while, but it doesn't work yet.
When I select Bluetooth as source the "Music" app (from Samsung) starts instead of Xiialive, whatever setting I use in Xiialive for "Media control". It could be an issue of my phone (I believe it is), but certainly other people have met this problem or even solved it.
Please, help. I haven't found other app for listening online radio which could de controlled from the car's unit with the "previous/next track" button.
