Has anyone figured out a way to disable the Navi system safety override that prevents you from using it while moving? I hate that feature when a passenger could easily operate the system but is not allowed to.
GroundLoop said:I agree. I haven't dug into the pinouts in the service manual yet, but there might be a signal to the head unit that the car is in "Park", much like the one for Reverse. Hopefully that's not moved to CANbus.
There might be a wheel rotation signal that can be interrupted as well -- effectively making the nav think the car has stopped, until GPS convinces it otherwise.

It's all in the CAN-bus, however maybe a false speed signal could be sent to the navigation system... Hmm...TEG said:Is the vehicle speed signal a single wire that can be tapped into?
I found one on my wife's Highlander and put a switch inline so you can disable the signal while in motion and get temporary access to nav input. But the GPS gets a bit confused if you leave it off so you can't leave it disabled for long.

TomT said:I believe that you might find that you also have to disrupt the GPS antenna signal...
keydiver said:I'm betting NOT. Why would they make it so much more complex than they need to? They have a simple speed sensor to do the job of disabling access, and why clutter it up by also looking at the GPS?TomT said:I believe that you might find that you also have to disrupt the GPS antenna signal...
keydiver said:OK, to put all controvery aside, it works! Its a simple matter of cutting the gray/silver striped wire to pin #28.
