First I would like to Thank bdl99(Brian, I guess) for creating this thread.
I tried the DIY solution following the diagram provided by Brian:

I'm using a SPDT slider switch, when the switch is on one-end position, everything works like normal(watching movie with e-brake on, GPS acts normal), however, when the switch is on the other position, the GPS gets no signal as expected, but it wont play video on screen, the reason is the system doesnt get e-brake signal.
I followed the wiring diagram as shown here(
with DVD and Nav override):

My question is: where should the PIN65 grounding wire connect to?
Thanks in advance for any help!
