2013 Navigation Hack - Bad News
I have Good News and Bad News regarding the Navigation Hack on the Fujitsu-Ten Navigation in the 2013 Outback.
The Good News
I was able to locate the wire that carries the Parking Brake signal to the head unit. 12V indicates that the parking brake is not on. 0V (GND) indicates that the parking brake is on. I cut the wire and attached it to a ground point. The info screen now shows that the parking brake is on all the time!
The Bad News
The Bad News is that it doesn't matter. The Navigation doesn't seem to actually use the parking brake signal for anything - the speed sensor overrides it. If you are going > 5mph, the navigation is locked out, even if the "parking brake" is on.
Unless other information about the navigation unit comes out with how to disable the lockout, it's not going to be a simple matter of tricking the parking brake.
More Bad News
While looking for the parking brake signal, I figured I should look for the reverse signal as well. There isn't one. At least, not a direct line from the reverse lights. The only wires I didn't check are the antenna + video connectors on the back of the unit. Best as I can guess, the only way this can work is if the reverse video turns on when a video signal is present. If that's the case, the hack to see reverse video when not in reverse would involve hacking wiring elsewhere to turn on the reverse camera, not at the navigation unit. This is conjecture, though, taken from the fact that I checked every normal wire going into the navigation unit, and none of them changed from 0V to 12V when reverse was activated.
Don't cut any wires, it won't get you anything.
