yes, you are partially correct. The M45 also has a speed sensing wire linked to the nav, so even if you have the parking brake switch grounded - it still reads that the car is moving and will deactivate the screen.
Search for the NAV Hack for instructions on how to bypass this, I have done it as well as many others with great success.
