I've just moved from iOS to Android, purchasing the new Galaxy S3. Lovely phone; I'm impressed thus far.
The only thing that I'm struggling with is playing audio, via USB, to my car's head-unit.
I've got a 2012 Nissan Juke (upgraded Nav head unit with USB port in the center console) which worked fairly seamlessly with my iPhone 4. I'd plug the USB cable in, and my music would start playing through the car's speakers - with names/album/length etc. displayed on the head-unit's display. This worked with music I'd loaded on to the phone and the Spotify app.
When I plug my S3 in, the phone detects the connection and asks what mode I want to use - Media mode, or Camera mode. Regardless of which mode I use, the head-unit is unable to play either stored or Spotify music.
I've read up a little, and I'm wondering if this is to do with the S3's inability to render itself in Mass Storage mode.
Does anyone have any suggestions for a workaround, or an app which might resolve the problem? I can play audio via Bluetooth, but its interface isn't as seamless and I will forget to turn Bluetooth on/off; don't want to drain the battery excessively.
