Tried playing music back through my headunit this morning, Alpine W203Ri double din, but kept getting the message "UNIT ERROR" come up. Have looked in the manual and it just says the USB stick might not be supported by the headunit, use a stick with is supported.
Any suggestions, the stick is brand new so its not like its ancient or anything.
The music I added to it, I literally selected in iTunes and then dragged it onto the stick itself. Have I done it the correct way? Have just looked at the music on the stick, and the majority of it is in M4A format, but there are about 20 which are MP3 version. I can appreciate it not supporting M4A format, but its not even picking up MP3 versions.
