My 2015 would on occasion be driving "backwards" like the destination and origins were reversed. It was amusing, then got really annoying.
It also got lost a lot and often my gps would be hundreds of miles off of where I was, or the car would just go back "home" to michigan.
Never seen the nav or anything in reverse but the camera. Even if the radio was blacked out dead stack, the reverse camera worked every time.
Now if you got in and forgot to unplug and hit start and shifted quickly enough the car would not lock the shifter and you could put it in reverse or drive and it would chime and hold the parking brake, but still move while plugged in. But only a tiny brief window during initializing.
My car had lots of issues though..
