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.

Summary

Don't cut any wires, it won't get you anything.

I was hoping that was not the case. I wonder if Subaru went to the speed sensor after seeing all the sucessful hacks around here??

I am unfamiliar with the situation here, does the navigation system completely lock you out if you are travelling faster than 5 mph and you want to be able to enter new coordinates?

If that's the case, my guess is they are using GPS coordinates to calculate your speed given that is what every GPS does these days, so what happens if the GPS loses signal? Does the GPS unlock because it does not know if the car is in motion?

I'm guessing it's a Fujitsu thing more than a Subaru thing. Fujitsu uses the speed sensor and a gyrometer to improve dead reckoning when the GPS signal is lost. I did read a forum post about somebody with a Toyota Prius that disabled their speed sensor with a switch so that they could enable/disable it at will. The navigation kicked out a scary error message, but the hack worked to disable the speed-based lockout.

Yes, It also locks out manual phone dailing and the phone book.

Fujitsu-Ten (Torrance,CA) responded to my email advising to contact SOA for wiring diagram.
Speed sensor it is, after all....I am checking with Toyota/Lexus telematics div. (also in Torrance, CA) to see, if they have similar units in their vehicles although they seem to be busy with i-phone apps and voice recognition issues linked to their units (as I have described elsewhere on this forum).

This is not good news at all. As much as I respect safety I hate the lockouts they put in Navigation systems. The major problem is some of the functionality to me is not much of a hazard and more of an annoyance.

Keeping fingers crossed someone figures out how to disable the speed sensor.

Yep - I have put back my 1490T Nuvi on the windshield and wired it down to the fuse box below.

You CAN do that, but you probably don't want to. The Navigation uses the speed sensor for dead reckoning, so you'd be disabling functionaility

It doesn't completely lock you out - it just locks out certain features: Entering a new address on-screen, searching for places, calling phone numbers that aren't on speed-dial, navigating folders on iPod, etc.

It doesn't use the GPS for that speed - it is interfacing the car's speed sensor. It also uses that speed sensor input to perform dead-reckoning. That gives you accurate navigation even when GPS signal goes away (tunnels, dense city/foliage, etc)

Makes the situation even worse for me. I wonder if there is some other way to disable the crippling functions via some hidden menu of some sort.

Anyone have any close buddies working for Fujitsu-Ten?

It's possible that there are some unused pins that help the problem, like they did with the Kenwood. But if Fujitsu-Ten doesn't want to give out a pinout, there's not much to be done to find what those unused pins do. Subaru doesn't use them, so they won't be in wiring diagrams.

There are actually a couple of unused CONNECTORS on the back of the deck. I have no idea!

I know it sucks but jeez its not the end of the world. Buy a 7" LTE tablet, tape it over the nav and be happy.

The reason that the system is disabled by default is to prevent distracted driving which, for 2012 to date, has resulted in almost 1.1 million accidents! Distracted driving is quickly on track to become a more severe problem than DUI.

Think very carefully about whether or not you want to put your life, the life of your loved ones, or the life of another family at risk because you want to override an important safety feature.

There is a conclusive body of scientific evidence to show that driving while texting, smoking, using the navigation system, etc. results in performance equal to or lower than driving while intoxicated.

No matter how good you think your driving and multi-tasking skills are, I assure you, they're not.

So then, should cars be speed limited to the road they are on? This would be easy to do with a GPS location. The last thing we need is more rules, what we need is common sense and personal responsibility.

Please explain to me how it is unsafe for my wife to type in an address as I drive down the road. It would sure be nice if she could, and as soon as a solution is found, I will hack/mod the GPS to enable it.

Explain to us how the car can tell that the passenger is typing rather than the driver. Solve that (and I'm sure it's just a matter of expense), and it's a game changer.

Not many people have a passenger in the car with them 100% of the time to perform such tasks as receiving/placing phone calls, entering navigation, etc. The car has a voice command system to assist with such tasks as a trade off.

The first rule of removing hazards is to engineer them out completely. Common sense and personal responsibility have nothing to do with whether or not an individual can operate a vehicle safely while performing tasks that distract them from the primary duty of being behind the wheel.

You are welcome to do as you please and no one is saying you cannot, but you have to understand that with every choice we make, there are potential consequences. In this case, the consequences can have a severe impact on you, your family, and the lives of others.

Actually Land Rover has an amazing system that allows the passenger to see an entirely different screen than the driver due to their viewing angle. It would be interesting to see if this catches on and becomes more mainstream. It would be a great solution to the problem you pose in allowing the passenger to assist with secondary and tertiary driving duties. However, as Georgeh points out, cost is likely a big factor.
