Yeeeeeeehaaaaaaaaaaaa. Since it doesn't seem like the software thing was going anywhere I ordered the KP technologies "OK" button bypass. I just took the dash apart tonight and pulled the nav and radio. I figured out which wire to connect the KP unit to. I am working on installing it now, but thought I would come in the house and share the good news. Not sure if anybody else has hooked this up yet. This is about as difficult as installing the window roll up module, except that you have to take the dash apart, which is not hard, just more complicated than the door panel. Will post more when I get the chance.

Picture of the wire that gets grounded to press "ok". the tan wire on the left.

 

This came up a few times in older posts. Glad you are trying it out! Keep us updated!

 

definitely keep us updated...glad you had the cahones to take everything apart and figure it out...good job!

 

A little vid for your enjoyment... 3.4 Meg

Right Mouse click here and choose... "save target as...."

 

Thanks, no problem, that's me on the sportbike with khakis and loafers. I am not afraid to take anything apart. My Taurus SHO has been apart to the ground. I've had the 5-speed gears in my HANDS! Nothing like touching the inner guts.

 

Yeah... heard about this but hadn't seen it done.....

 

nice! Cost? Where did you buy it from?

 

$40 http://www.kptechnologies.com

I'm done the install. I will post more when I get a chance. I will be working straight ahead until this weekend.

Nice mod! Great job on the install guide there!

 

Awesome news! Do you mind if I link from the KPtech support forum to the information you posted here?

 

Nice. you may be my hero. Keep us posted on if the mod works.

 

whoa! so it actually works? I was considering buying it and trying it out. Unfortunately, the wait time to get the map is still long

 

I still don't understand why Lexus and Acura have the most invasive navi nag. The warning on the MB just goes way about 5 seconds after start up and the BMW is a tap on the iDrive anytime after start up. The acura ties you up to make a point I guess.

It sounds like this mod hits the OK button but you still have the delay.

 

With the mod, what screen does the navi load to? I would like it to be audio, however, I assume it is the map.

 

The Nissan system requires you to press the OK button to, and goes as far as to prevent you from actually using the NAV system if te vehicle is in motion!

 

Nice work, and props on actually ripping the navi apart to do it. I dont know if I would want to try the mod but that OK is sooo annoying.

There has to be a software way to get it cracked. I would love it if it would just show a loading screen, no warnings, and go straight to the navi without an OK button.

Again, nice work.

 

what if the tan wire always had ground?

 

If that tan wire is in fact the 'OK' button and you grounded it continously the Navi sysem would most likely ignore the input all together and consider it faulted. If it doesn't ignore it then the 'OK' switch would act as if it were stuck, always being electronically made.

 

You could test that by holding the 'OK' button in manually with the car off, then start the car and never let go of the button. start and restart the car a few times and see what happens.

 

How much of a time delay did you put on the unit?

 

As much as you need. Its adjustable between 0-30 seconds through a small knob on the unit.

 

I managed to get on the internet from work. (Hospital) "IT" has it blocked, but I pulled the sam file on a machine and got the supervisor password.

Anyhow the unit is working, but I need to increase the delay just a tad. Sometimes when I start the car the computer takes longer to boot up. It seems like the car navi unit boots up in different amounts of time sometimes and I have the unit set to "hit" the OK as soon as possible. I think the OK button comes up in about 25 seconds. If the nav takes longer to boot, then the pulse misses the OK button. I just need to extend the time a little I think. If some of you out there can time yours and see if we match.

Somebody was asking if you ground the ok all the time. You can't do that because then the nav features of pressing buttons wouldn't work. The wire that gets grounded is the same as you pressing straight down on the silver joystick. I took the board out of the buttons and joystick section and sat with a continuity tester on my meter until I figured out where the signal was going when you press the joystick button in.

For anybody doing this mod you don't have to dissasemble any electronics. All you have to do is get the radio and nav unit out. They come out in one unit. Take 4 screws off the back of the nav screen which release a metal cover and that will give you access to the tan wire. Then just use a quick connect and connect the KP wire to it. Attach the KP unit to 12 volt when ignition is turned on and ground and get the timer set right and your done.

I mounted the unit on top of the radio, but I think I am going to move it to the top of the nav screen. That way I can pull out the top vents and have easy access to the KP unit.

I will attach some more pictures when I get home.

What a hacker you are!

Looking forward to the additional pics.

I'm interested in how the module looks like.

 

OK so I've got a question. I have the Canadian model of the TL Navi system which gives you on the same screen as the OK button, a "Francais" button to switch the Navi to French mode. I'm assuming that if at the nag screen, a middle click of the joystick hits OK, this mod should work for me as well right?

 

OK - I watched the video... all this thing does is push the button for you??? The warning screen stays, with the same delay - then unit just automatically 'pushes' the button.

Am I missing something - I mean what's the big deal about pressing the button yourself?? I could see value if this mod eliminated the warning screen or at least the delay but it does not appear to do any of this.

Seems like a waste of time and $, unless I am missing something??

 

Well ... there is already a NAVI hack to remove all the warning text, leaving just the button. If the button is auto pressed, someone might even be able to make the button color black - effectively, removing the entire thing from view.

 

The module simulates the 'OK' button being pushed, so if you can start up the navi system and just press the OK button then it should work. Also, if you push the 'OK' button at any point before it sends its output pulse it will cancel the automatic pulse, so you can still change to France mode if you so desire.

 

Nope, you didn't miss a thing. All it does is processes the 'OK' button for you. It does have the ability to do some other stuff, like turn on a DVD player or switch Navi to video (with a firmware upgrade, at least).

Its amazing how the 'little' things can be so annoying. I absolutely love my OK button bypass, it's actually my favorite module.

 

Yes, the module simply presses the ok button for you automatically. Well for me I hate having to press that damn ok button and if you get doing other things, the screen goes off and you have to press two buttons. I'm a tinkerer and love gagets. The car should have come with auto headlights that turn on at dusk and off during the day. Can you make that module KP?

I don't think you can get rid of the delay. I think it is the nav unit loading the software.

I did not take pictures of taking the dash apart. Basically you have to pry up on the metal pieces and they will pop off. I started at the center console box and worked my way up to the radio. They came off pretty easy, but near the radio they are a little stubborn and you have to pry with enough force to pop them free, but not too much as to bend them. They are made of plastic covered by a metal wrap. There are some good directions somewhere on the site on how to take the dash apart. I think they were related to the comptech short shifter. I did not remove the side panels or take the glove box apart. I simply pulled hard enough on the side panels to get to the screws holding the radio in. It was a little tight, but I managed. The two flip lid boxes underneath the radio attach to the bottom of the radio so you have to slide that forward to get it off the bottom of the radio.

Here are some more pictures....

This is a picture of the schematic board just for reference, You don't need to do anything with this.



This is the joystick switch on the board



Back of the nav screen after being separted from the radio stack. You have to remove the metal cover to get to the tan wire.



Back of nav unit. The two plugs toward the dash in this picture have the power and ground wires you can use.



Closup of wiring harness. The yellow/red wire has 12 volts when the ignition is turned on and the black a ground.



Back of nav unit and where I installed the KP module. I am going to move it to the top of the back of the nav unit. I think there will be enough room behind the dash and that way I can pull the top vents to mess with the delay if I have to. Probably not necessary though. Once you get the delay set you should be good.

oh so this module does it simulate pressing the push knob.... so grounding it all the time would not work....

 

Very nice. So let me get this straight. You just need to remove the headunit and tap 3 wires in the back of the unit? Or do you need to take the headunit apart?


Instructions on removing the dash

 

FAST4DR, I installed auto-headlights on my car with the DEI 545T. They work perfectly. I never touch my headlights switch. I posted a DYI somewhere on Acurazine. If you search for 545T, you should find it.

 

fast4dr, I have a question, although off topic. Does the stock headunit have rca outputs on the back of it? I am looking to get a sub and amp. I know I can tap off the center sub in the back, but I am curious.

 

Awesome pictures!

 

Will, What do you tap the red wire on the kp module into?

 

You need to take at least pull the headunit out from the dash and remove the 4 screws on the side of the metal case holding the screen to the brackets. Then remove the 4 little screws holding the metal cover on the back of the screen. That will give you access to the tan wire. The other two wires (power and ground) are on the harness attached to the screen as seen in the pics.

You might as well pop all the plugs off the back of the cd/tape/lcd and pull the whole unit out. Then you can remove the screen and have a little more room to work.

Will

 

Hey Thanks!! Might just be my next mod. I need to put it on our outback also. It's headlight system is worse than the acura.

 

No other plugs other than the harnesses.

 

I guess it looks red in the picture, but it is actually orange and it goes to the tan wire on the back of the lcd screen. It grounds the tan wire simulating you pressing the OK button.

Will

PS. There were two other wires attached to the KP unit that I did not use and pulled from the harness. One was for a backup camera sensor. Not sure what the other one was for.

 

The purple wire is for a back up camera, it basically pauses the count down if the car is in reverse. The green wire is a VSS interupt output. On the Nissan/Infinitis you can't program the navi while in motion, unless you 'trick' the navi in to thinking the car is standing still. So, if you press the 'OK' button twice quickly it will energize that output and keep it latched for as long as you are inputting data. This can also be switched to a general purpose on/off output through a firmware upgrade.
