Hello Blake,
The Ford Focus does not support controlling the AC via the screen. In most cases, if the original factory display allows AC control, then our unit should also support it.
Regarding the issue of the bottom AC buttons not disappearing, you can go to:
Please press Setting– Factory Setting (enter password3368) - Car model to choose ”, and change it as shown in the image below. This should remove the AC buttons.

For the instrument panel temperature unit issue, I would like to confirm the following:
- Can you switch the unit option in the “Vehicle Information” menu?
- If not, please check whether the 8-pin CANBUS connector on the back of the unit is properly connected.
- If you can change the unit, but it reverts to kilometers after restarting the vehicle, please refer to this post to resolve the issue.[Login to see the link]
Since you are using a vertical screen, click [Login to see the link] to download the corresponding firmware package for vertical screens.
Let me know if you need any further assistance!
