Navigation Input Override (Speed Sensor Bypass)

Yes, tried it. Other than adjusting the mic volume and checking the sensor performance, you can't do anything real meaningful. No override of the lockout.

 

I will have to look for it, but there is a video on YouTube somewhere that shows the process to override the NAV on a Prius. It may be an earlier model, and the commands are similar to what was mentioned a few posts back. But in the video the guy actually enters the command and displays the funtions as he is driving. The hack is cool, but the software fix is a much easier and cleaner option. I will post the link when I find it again.

I think this may be it, I can't view it from work so not sure: www.youtube.com/watch?v=RvW6k0Q1wV8

 

Okay, forget my previous post, I've been digging deeper into this and I have more info now. I've read a couple of things, but still think there are more menus available that I have not yet found. That being said, I have confirmed that there is a service menu and I have been in it myself. However, there are no "override" buttons as in previous versions. When I say versions, it would seem that through what I have read, the latest DVD for the NAV makes it impossible to access the complete programming menu. So when they make changes at the dealer, they maybe place in a special "service" DVD to allow modifications. Now if any of you would like to take a chance in playing around in the menu I was able to locate in regards to button testing, GPS coordinate testing, color bar testing, and a few other little items, here is the process. Now before I post the sequence, I have to prefix it with a disclaimer that I do not know what kind of damage you can cause if you go plunking around in this menu. Here it is...

Turn the car on.
Wait for the map to show.
Press the "DISPLAY" hard button on the bottom right.
(this will display the contrast and brightness sliders)
You should also see the map in the background, with a TEAL colored borders at both the top and bottom of the map.
It is between the TEAL lines you must enter the taps:
TOP LEFT
BOTTOM LEFT
TOP LEFT
BOTTOM LEFT
TOP LEFT
BOTTOM LEFT
From here, proceed at your own risk, lots to look at but not what we are looking for.
Hold DISPLAY to exit.

SHORTCUT FOR THE ABOVE SEQUENCE:
Hold DISPLAY while turning your lights on and off three times!
Once your in, you can again hold DISPLAY to exit.

Another menu I stumbled upon:
Hold INFO while turning your lights on and off three times!
Hold DISPLAY to exit.

I'm sure it is a matter of time before someone finds the magic combination to get us where we need to be to see the lock/unlock settings, the beeper settings, and the NAV safety bypass. I hope this helps further our quest! Have fun!

This is how it works on our Lexus. However, this backdoor (override) was removed in the newer versions of Toyota GPS - hence I can't upgrade without losing this ability... Looks like they pulled it out for the Prius too...

 

Whoohoo! Congrats! Any chance you could diagram your completed circuit for us? Tia.

 

The sequence I posted was tested by me on my three day old Prius III.
You are correct that there is no "override", but there are other menus available.

Has anyone read this?

Just for the record.. I think the whole thing is silly to lock us out... you can fiddle all you want with your stereo or CD player and fumble through songs and list and stations as well as play with your air conditioner controls and other functions in the car, I think finding a location is no more driving intensive than scanning for channels or playing with your CD changer, cell phone, texting, ipods DVD players.. especially ejecting and putting in new CDs... what happened to common sense?

Next they will try to make it illegal to pick your nose while your driving!

Too many crooked lawyers twisting common sense into a profit.

 

Do you still have to remove the center console and disconnect all the wires etc?...

Its great you figured out a simple circuit... I'm now trying to figure out a simple install.

Funny... I did the "cut wire" hack on my 2006 prius and although the satellite would update my position in a staggered delayed way "due to no dead reckoning", I could leave the switch switched as long as I wanted and I maintained ability to changes settings without it reverting back in 30 seconds like you say.. not sure what the difference is.

I'm very interested in your solution... just wondering whats the easiest way to install it now that you've done all the hard work yourself.

 

Yep - exactly what I found too.

What frequency (or maybe R1, R2, and C1 values for the 555 timer) did you end up using for the timer circuit?

Thanks hawkmoon! Glad to hear it's working as expected!

 

Wow - that's someone with entirely too much time on their hands!

 

Too bad. I had hoped that we could at least change the cut-off speed. Thanks for trying.

 

For what its worth... my wifes phone is too stinkin sensitive and picks up every noise in the car, including my own voice coming out the mic and goes back into the phone and causes me to hear periods of silence as the vox on her phone kills the audio to echos of my self.
In the hidden menu I went into the bluetooth settings turned down the input sensitivity as she drives a prius too.

 

Why Toyota bothers to hide stuff like that in a hidden menu is beyond me. There is not obvious safety issue. If it were just to generate income at the dealer, wouldn't they do it for more settings. Weird...

 

I think it has to do with the general knowledge base of customers as most would just screw things up and then complain to Toyota about it.. similar to people wondering if there is a warranty on their computer because it comes up with a "blue screen" because they loaded some conflicting drivers that jams windows logon

Operator error is 95% or more of the cause of computer related issues. Not that the operator is wrong, they just don't understand the software enough to be tweaking it.

Its good they allow others who don't mind venturing at their own risk to do so.

Now, if they would just do the same think for the Nav over-ride.

I don't see how they could ever be sued for a hidden menu that allows the customer to allow continual input to the nav regardless if moving.
Even if it reset every few weeks, or even every time you started the car... at least you could set things up for a long trip.

It would be obvious in court the customer was doing it on purpose.

But then you get lawyers that sue MacDonalds for the customer spilling hot coffee on their laps because they are clumsy.... I guess they ordered "cold" coffee?....so.....

At least they could make it easier to mod ourselves so they would be released from liability.

 

Actually a lawyer did not sue MacDonalds, a customer did. And I believe that a jury (who actually knew the facts) concluded that MdD's was more at fault. Now if you want to talk about lawyers who seek out named plaintiffs for class-action suits in which only the lawyers receive any meaningful compensation, then that's another story....

But still, of all the settings to hide, the Bluetooth microphone volume would be close to last on my list.

 

I guess its your vantage point... and not sure why your so sensitive about the subject, but the lawyer could do nothing without the customer, yet the customer could do nothing without the lawyer.

I think the customer filed and the lawyer did all the talking, arranging, and actually did the sueing as we have made ourselves dependent upon their influence and skill before we can bring a cause against another..... nevertheless, without the crafty wording and working the laws that were made for man into a twisted image of "man being made for the law" it could never happen.

People who make a living twisting truth and justice in the name of standing behind the law they misrepresent is a sad excuse for a living.

Yes, the criminals need representing too.. that doesn't mean they are right, nor does it mean they should win.

Evil has always been in the hearts of men.. but without crooked lawyers and judges, only justice could be served instead of these ridiculous lawsuits.

Jerks like this is why you can't have access to your navigation.

 

Trial lawyers may or may not have anything to do with the NAV lockout being in place, but they most certainly nave NOTHING to do with our efforts to overcome the lockout and they therefore have no place in this thread. Please drop this subject and return to topic. Thank you.

:focus:

 

Lawyers have "everything" to do with why we can't access nav while moving..... give them enough rope and they will also have something to do with our efforts to overcome it.


When you can put in a burglar alarm system and then get sued because the burglar cut his hand busting out your window... yes Toyota could also get sued in spite of efforts to overcome their protection against it.

Thankfully you have to have more than 330 posts before they deem you wise and knowledgable enough to become a mod on PC.
