I was wondering if anybody could tell me if their Bluetooth in car setup displays the song info on their display in-car. If it does, what app are you using? I am using Doubletwist and it doesn't display the song info in my car. I'm pretty sure its not a limitation in the car, more an app issue.
So, I guess ultimately, a list of music player apps that send song info over Bluetooth in-car is what I am looking for.[/QUOTE
I have all my music loaded into Google music and since Sprint is horribly slow I rarely stream music while driving, I use a thumb drive or CD's. I have a Kenwood DNX9180 and I never paid attention to what was on the radios display.
What brand of radio are you using?
I will load some songs on my phone a give it a test. I use to use Winamp as a media player because they had cool internet radio stations.
I would imagine with the A2DP profile it should display song/track info(metadata) and with AVRCP you should be able to control the phone from the radio. It may be a software issue with the radio and not with the phone.
A few weeks ago I installed a Pioneer AVHP2400Bt into a customers car and he had a new iPhone 5. It would not display the metadata on the screen while streaming but with the USB it would. On the website it said Pioneer is coming out with a firmware update for IOS 6.
Look at this bit of info.
