My USB plug doesn't register my android phone as an mp3 device

Hey everyone. I recently bought a USB cord to connect to my android phone so I could listen to my songs. I plugged it in and switched to the correct mode to play my music off my phone and it worked.

But, after having it work the first time I plugged it in it won't work anymore. Has this happened to anyone else? Cos I was hoping someone had a solution or any idea what happened

 

I haven't tried plugging my android in. I use Bluetooth audio when playing music from my droid. Works good.

 

What is your USB option set to for Android? MTP or PTP? Also what version of Android are you running? It's not a truck issue, its the way your android phone is communicating to the truck. The newer version of Android doesn't support Mass Storage Device and only uses MTP and PTP.
