USB to AUX, have bought this
 

Hello Volvo fans,
My name is Nebojsha and I come from Serbia, Novi Sad.
Anyhow I have one question. How can I make volvo s80 2008 with only AUX input let music from USB stick ?
I have bought this stick, but it doesn't work.

You may find that the recordings on the USB stick need encoding if the format is wrong it won't play, try one track first and see if it works by right clicking on a track and using a different format.
