The song incidentally featured on the car’s surround sound is “Dreams” by Gabrielle Aplin & Bastille, which is available to download on iTunes here: https://itunes.apple.com/gb/album/pan…
I do not own this song.
This is a demonstration of the “hidden” service menu on the Black Panel Display, which I have unlocked. This also shows the instrument test.
To bring up this menu, press and hold the trip reset button between 10-12 seconds, with engine or ignition on. Ignore the engine oil reset opportunity and keep the button held until the menu appears.
Press the trip reset button to navigate.
Hold the trip reset button to enter and exit menus.
I hope this helps as a guide/tutorial!
