We can't be sure exactly what happens, but by the looks of things, it fries the configuration memory, meaning that the dash's configuration is lost. With the memory fried, it reverts to the default, which is Km. Reprogramming won't help, because the configuration memory would have to be working in order to save the changes.

I don't doubt that it's fixable if you can identify the fried components, source suitable replacements and have the surface mount soldering skills to do the job. The problem is that, as far as I'm aware, nobody offers this service and nobody seems to know which bits need to be replaced.
