Anyone know if there is a way to hook up a USB port to a HU that has AUX In? I would like to use a flash drive to play MP3's

 

Unless your head unit has a USB port then no you cant connect a USB flash drive through aux to play music.

Your options would be to get a new head unit that supports USB devices, or use a MP3 player to play your music instead of a USB drive.

 

OK, I thought that may be the case but no harm in asking I guess. I have a good HU so really dont want to get rid of it. I will look into an Ipod
Thx
