The term "RSAG7820" usually refers to the model (commonly manufactured by Rise/Right suppliers). However, the firmware is specific to the Screen Size (UI resolution) and Can-Bus Protocol .
The text printed on the circuit board usually looks like (for example, RSAG7.820.5687 or RSAG7.820.6334). However, the board number alone is not enough to find working firmware.
