Lots of variations! My 2017 XLT with navigation has Sync 3 (hardware). Firmware is up to 3.0 or something now as well.
No mini-plug Aux input in my '17 console (or anywhere else) I can find, just a pair of USB ports and a 12v socket. 12v socket in the right lower dashboard mirroring the transfer case switch placement on the left. A useless empty bin mirrors the brake controller -- gotta have symmetry.
Rear seat has 12vDC and 120vAC outlets.
The 12v outlets remain On all the time. I hate this "feature."
