SUCCESFUL/FAIL: Success
LEVEL OF DIFFICULTY: easy

INTRODUCTION
There is a hidden diagnostics menu available in the entertainment/navigation system that lets you play with all sorts of weird and wonderful items. Of the most interest (to me, at least) was the ability to switch on the reverse parking camera while driving normally.

WARNING: As I'm uncertain of their purpose, I strongly recommend you avoid the "memory" functions available in this area. Alternatively, if you know what they do, please add an update to this topic.

STEPS
1. Hold down the INFO button (to the left of the screen)
2. Whilst holding the button turn the lights from off to on (not auto) and back to off 4 times until the menu appears

To access the reverse camera, press the MENU option at the top right of the screen and select the CAMERA CHECK option. To exit the diagnostics screen, press and hold the DISPLAY button until the system reboots (you'll get the "I Agree" screen again). See attached photos below.
