Thanks!
I don't know why I waited so long to do this given I've got boxes of old computer parts always sitting around. I found a 4 pronged computer cable that worked along with a nice 3+ foot headphone cable (think old school, not ear bud cable), ran that underneath the shifter/cupholder area, drilled a small hole next to the charger socket in the center armrest area, and now all is good. Gigs and gigs of music from my Android with perfect sound reproduction. Nothing too elegant with my approach, but the charger and aux cable just sit in the armrest when not in use so no problems there.
