I believe from Samsung that both of theses phones include rSAP, but they cannot guarantee the the system will work with every car manufacturer, has anyone used either of these phones in a recent model Superb, (Mine is only a  month old)

I would be very interested to hear of other users experience FAILURE OR SUCESS with either of these phones before I go out and buy one

If it's modern Android (which it will be) to get it to show up through radio USB you need to go to settings and change the USB mode to MSC through USB Connectivity, then your media files will be readable,

 

Better still get an Xperia Z, much nicer quality phone and it's on 4.2.2 now as well.

Samsung Galaxy S4 connects via Bluetooth RSAP fine with my late 2010 car - which can also connect HFP phones too.

Sorry I thought you were asking about being able to send songs down it rather than BT.

I can confirm that the S4 mini does work in rsap mode with Skoda Bluetooth Premium as I tested one in my L&K today.

When it was first connected it did so in HFP mode. I had to go into settings in the car Bluetooth settings and select Premium which then kicked the phone into rsap mode.

Additionally the S3 will work in rsap mode.

However, if you ever come across the dual sim phone Samsung Galaxy Grand this only works in HFP mode.

Hope this helps?
