I just moved from my iphone to andriod (Galaxy S4). I bought a audi mmi cable which can connect to microUSB. When I tried connecting the phone, the phone charges correctly but then the source section of the interface says "unsupported device". So wasnt able to play any music from my phone.

Then I tried using a 32gb sd card where I loaded all my mp3 files and inserted in the SD card slot, hoping that I will be atleast able to play music from that. There it gave me a message saying "No Playable Media was found". I tried loading just a bunch of mp3s in the root folder of the SD card too and it still didnt recognize.

Any solutions for this?

 

Did you get anywhere with the sd card?
