FINALLY got lossless music out of my iPhone, through a standalone DAC, and into the car while still charging my phone. Big thanks to MarcoZandrini for the help on this!

This only works for cars with Aux-In armrest input, but you need:

Apple Lightning to USB 3 Camera Adapter
Audioquest Dragonfly (I used Red)
Short audio cable (I used one from FiiO)

From there install is very self explanatory, you plug your phone into the Camera Adapter, then hook up the Dragonfly to the USB and attach to Aux In. You then use a lightning cable to plug into USB for power. Proclip users, you need to replace your standard lightning to USB cable that came with your dock with this one on Amazon:

EMATETEK Extender Cable Connector Pass Audio Video Music Photo Data and Power Charge. 1PCS Male to Female Extension Cord Made of All Black PVC &Aluminum. (6.6 Feet / 2M)

You will need to file the hole in your dock a tiny bit, 30 seconds of work.

The photo below if from my wagon, I did both cars. The only difference in this case is that I had the OEM phone cradle, which I removed and added an additional USB outlet down inside the armrest. I plugged into that instead, but it works the same way.
