Initially, the graphics were brown and black, and this system became known as GEN1. The colour scheme of the display were then changed to Grey/Black/Red at the same time as the graphics in the instrument cluster changed and this is known as GEN2 and coincided with the MY2013 update. Initially different firmware was used in GEN1 and GEN2, but later on the firmware for GEN1 and GEN2 was merged into 1 firmware release and the colour scheme became a run-time configuration item.
