I have a 2015 Ford Expedition Limited.
There are not redundent controls for all of the controls.
The rear HVAC control on the front touch screen can only be accessed with multiple screen touches (when operated by the driver or front passenger). After several moments, the rear control screen disappears and must be selected again to use it. I do NOT like this feature as it is poorly designed. The control can be set for the second row passenger use, but it is cumbersome for the driver and passenger to adjust.
When the vehicle is started, there is a noticeable lag before the radio station activates. Often, the song/artist listing is displayed that was present when the car was shut off is still displayed.
The voice recognition system is terrible and I no longer try to use it.
This is my first Ford and I am not very satisfied with the control system. I do like most of the other features and the vehicle overall (although there are some very poorly placed switches).
Yea, I forgot about the rear control. I usually just have it selected to the rear seat area control. You are right, it is rather annoying.
Also, I don't use the radio that much, but I know what you mean by the lag after starting up. For me, it didn't seem all that off from every other system I used (OEM and aftermarket alike), so I guess I am just accustomed to waiting a few seconds for the radio to fire up. But again, It is a valid complaint and point.
As far as the voice recognition, I am not sure if you have tried it, but I ran the learning utility where the device listens to your voice as you are speaking a preset number of phrases. After I did that once, it was almost seamless. Not perfect by any means, but up there with all of the other voice recognition devices (including Amazon Echo) I have used.
That being said, I still prefer to push buttons with my hand vs speaking out loud.
