How to listen to music from Nexus 4 (LG) thru AUX in 2009 Yaris?

Which the car stereos I had in the Europe of the '90s did. Advantage? You could keep the discman running on a pair of AAs for many more hours because it didn't need to provide an amplified signal, just a signal.

I guess that wouldn't work at all with the standard aux-in jack on a Yaris.

If you ever plugged a headphone into one of the "non powered" ports, you'd find that it is just the same as the headphone jacks but without volume adjustability. Ie, max volume.
