I just got an 06 Odyssey EX-L with RES and I'd like to use the rear aux jacks to play audio over my speakers from my computer and MP3 player. Numerous other people say they've done it, but I just can't figure it out. I've plugged in audio cables. I've tried to use the Aux/XM button (It does nothing). The manual says almost nothing about the aux jacks. Thanks in advance for your help.
