Now, let’s restore the true tone with the multi-functional programmer.

First, connect the display extended module with the programmer. Next, connect the original screen with the display extended module.

Once finished, disconnect the original screen and connect the aftermarket screen with the display extended module.

This time we use the programmer to write the data to the aftermarket screen. Once finished, disconnect the aftermarket screen.
