Hello all. I'm looking for some help with an audio playback issue. I've recently purchased a 2006 Honda Inspire. Inside the armrest console there is an aftermarket device (pic attached) attached to some type of serial cable. There's a 3.5 female aux connector on said device. I'm struggling to find a way to establish audio playback through this device. It doesn't help of course that the menus on my internavi system are mostly in Japanese. Gas anybody had experience with operating this type of setup? 

Regards

Kane
