[ KB ] How to enable NAV system defeat with the touchscreen

To access the override, you used to press MENU, VOLUME (etc). Those sound like MFD firmware functions rather than NAV functions. Not sure what the specific mechanics were after you pressed OVERRIDE, but since there's a speed input to the MFD, I'll go out on a limb and say the graying out of the buttons was a MFD function as well. Could be the NAV software only defined what buttons should be grayed at speed, and the MFD did all the rest. In this case the firmware in the '06 MFD is what's different.

When you speak of version 5.1, you are talking about just the map database version. The software on the DVD is not included in that version number. Since there are two different v5.1 part numbers (one for an '04/'05 and one for an '06), I would assume there is software on the disk, and it is different on the '06. I still don't believe the disk is the reason why the override doesn't work, but just saying v5.1 isn't enough to say the disks are the same.

A good test would be to pull an '05 disk and see if you can still get to the override. If you can, the override button was part of the MFD system...

 

First off, I believe that diagnostic screen is from the NAV. Pressing MENU causes you to have to press "I Agree", which is a NAV function. Ever notice that some non map based functions require the "I Agree" (such as calendar and maintenance schedule) while others don't? (like phonebook)

I think she was wrong, but I was talking to the parts lady while I was getting my oil changed, and she claimed that the 2005 5.1 DVD had a different part number than the 2004. Also, I believe the 4.2 and the 5.1 has the same software (for 2004/2005). It was 4.2 that added that sky blue line for routes that could not provide turn-turn guidance.

 

OK, I took the Nav disc out of my 05 I think it said version w41 and tried it in my 06. It would not work. I took the disc out of my 06 U40 and tried it in the 05 and it would not work. There might be a special way to reboot the system. But I was not sure. Anyone out there know if I had to tell the system that it had a new disc and reboot????

The only thing I want to add is that the NAV Enhancement Kit from Coastal Tech uses the NAV override trick that works with the '04-'05, but not with the '06. When you press the DEST button you see the same screens as if you did it yourself. Same thing with the "I Agree." It comes up for a couple of seconds and then the button changes color and the screen goes to map.

 

So it is looking like the only way to input while driving is to cut the speed sensor wire for the nav and hook it up to a switch. That way you can enter an address and once in reset the switch. The nav will have to find itself since you were traveling while inputing. Is this it then guys or is there still hope???

That's probably the case. If you go here, you'll see the plans.

 

I unfortunately touched the Loading button, being of a curious nature. Now the NAV system will not do anything except ask for a data disk to be inserted, and the deal and Toyota both claim I broke it. They've replaced the display electronics, and next want to replace the ECU for the GPS. Does this make any sense???

 

I couldn't find it, but it's something scary like disconnecting the front cables, removing the top of the NAV system and then disconnecting (and reconnecting) a ribbon cable. They also saw a reset button inside, which they pressed. That may have done the fix by itself.

In the end it worked, but everything had to be set back up again. When I installed Coastal's NAV kit, I had to reset the search area, and a couple of options on the MFD, but my POIs were still there.

Heh, efusco beat me to it, but that's the whole proceedure that I remember (and I don't remember seeing any photos of it).

 

I just tried this. Works like a charm.

I have been asking about this for months now.

Finding this website is a blessing!

Thank you all for everything. I have a feeling there is going to be a few nights of lost sleep due to browsing this place.

Doesn't much matter for you. It does not work for the 2006 and 2007 models.

I'm also getting a 404. I'd love to know how do do this.

Now I see Tom's post not working on 2006/2007 models. Since my wife's car (2006) is the one with NAV, I guess it doesn't apply to me either. Bummer.

But is there a problem with the PC Knowledge Base?

Thank you so much Evan. As always we can count on you. You are the best.
