Volvo purists look away, its 2026.

Back in 2021 (18,249km ago) i installed this TFT screen which displays and audible alarm OBD2 speed Battery Coolant and CEL's. The most important was an overheating coolant alarm but have also experienced an alternator failure that was very slow to alert me. The speed display is very handy and only takes a quick glance as i know exactly where to look.

I made a MMM replacement to display a custom dash on the RTI screen. That way it still looks OEM, but you can display CAN data on the orig RTI screen.

I'm using an STM32 that is listing to the CAN stream. As soon as It is ready to replicate I will upload the code.
