2013 Hyundai Elantra MP3 USB Port Findings

So i tried multiple usb flash drives to play mp3 songs in the vehicle.

As a test, I tried 10 different make/model flash drives, formatted them with the different types and copied 4 folders consisting of 10 songs to each.

When i say doesn't work, means the radio resulted in the error message of "connection error". Here is what i found:

* Windows NTFS, MAC OS HGST and Windows FAT format doesn't work
* Lexar, Kngston, PNY and Centon flash drives don't work
* Patriot flash drives formatted with FAT32 works
* Sandisk flash drives formatted with FAT32 works
* Tested sizes were from 8gb to 32gb

Have not tested an external usb hd or a microsd card in a usb adapter. Right now i am using a 32gb sandisk with over 1000 songs on it.

I like to hear from others what make/model/size and format your using in your Elantra that does play mp3's properly.

Thanks
