Just sharing my recent design for a smartphone car dock/mount/cradle/charger for my Galaxy S7 Edge in my 2016 Volt. I had a wireless charger that I liked but I wanted one that would plug into USB to support Android Auto integration. The drop-in design is custom fitted, incredibly secure, and easy to use one handed, in and out, no fiddling with USB cables.
The dock mounts securely without damage by attaching the vertical posts in the Volt's center console using a cheap ram mount attachment. The instructions on how to do this and all materials used are available on thingiverse http://www.thingiverse.com/thing:2041572.
Total cost of RAM mount, 3D printed dock, and hardware was under $20.
Also a short video overview, which also shows how I launch waze automatically in the foreground (using tasker) while still running Android Auto in the background: https://www.youtube.com/watch?v=fB2ULfGEWvA
