Several game versions ago – and a couple of times before that – the ‘truck info’ data was re-configured by SCS. At that point the displays in the cab of mod trucks for mileage, cruise control, fuel consumption, etc went completely black. In fact, I have a old version of KW T408-SAR and the GPS display is black. I cannot fix it.
You can specify which readout appears on the display panels in the truck. As I recall, the K200 in ATS uses the W900 truck info data whereas in ETS2 (because there’s no Kenworths) it uses the Man TGX data?
It should fit, but SCS change stuff from time to time without warning.

Also, you can write your own truck info file. Verrrrry tricky. RTA have done this before but it falls prey to game updates making it produce ‘unexpected results’ 🙂
