The Ford Focus MK4 is available with an analogue speedometer/instrument panel (IPC) and with a digital IPC. Here you can see a comparison of the two IPCs, analog on the left, digital on the right.

The digital speedometer can be retrofitted relatively easily.
As always, you can find out what you need and how to do it step by step in the video.

Below some IPCs on ebay:

The following speedometer models are known to me.
As always, the last letter indicates (as far as I know) the firmware version.
The main difference (as far as I know) is that NX7T-10849-SC* supports ST boot animation out of the box. NX7T-10849-SX* has the standard focus boot animation.
