So your saying you could program the unit so that when I press the ok button twice quickly, it would either ground or engergize that extra wire? That could be used as the switch for flipping over to a DVD or TV input. That would be awesome. No need to mount a switch anywhere.

 

Exactly.

It actually isn't two short pulses, its one slightly longer pulse followed by a short pulse. The first pulse must be a bit longer to prevent you from accidently turning on the (-) output while programming the unit for a destination.

 

The signal going from the stock head unit to the stock amp IS line-level, but it's only 500mV or something like that. Nowhere near the 2V average that aftermarket head units put out. However, there are amps that accept a line-level input at that voltage (JL Audio for example). I originally wired my system by taking the output from AFTER the stock amp and used level-converters to bring it back down to line level. I'm going to try going straight from the head unit to the amps now because I was getting tons of HISS in the background... There is a thread about this and it's pretty active, so you could monitor it to see how it turns out.

 

Not sure, but it seems I may be the second person to try this module in my TL.

Here is my findings:

I followed the install instructions found earlier in this post. It worked as described but only about 50% of the time.

After triple checking all my wire connectors, I am sure that it is the module itself that maybe defective.

After finding the right timing setting, I restarted my TL (probably 30-40 times). I used a timer to make sure the go/agree button was coming up at the same time.

Sometimes it would work, most of the time not.

All of the connections are right but it seems to be the module that is not working properly.

Very frustrating as this should have been a 45 minute install that took over 3 1/2 hours with an unfortunate outcome.

Anyone else try this yet? I am wondering if I am the only person with this problem...

 

wow...you can take your dash apart and put back together in 45 mins? Did you ask fast4dr if his works flawlessly before ordering your unit? Only thing I can think of is that the timing is still off from the KP unit to your navi system. Somehow the KP unit is getting power sooner than the nav unit and is prematurely sending the pulse before the OK is coming up. Sucks that is doesn't work..guess I'll just have to reach ALL the way up to the screen

 

It wouldn't be impossible for the module to be defective. If it is we will fix it for free under our warranty.

Things I would check first are:

1. Make sure the KPtech 'yellow' wire loses its voltage when you shut the car off. The module has to reset each time the ignition switch is shut off. I would leave the ignition off for at least five seconds before turning it back on.

2. Check your timing. This can best be done by using a volt meter on the KPtech 'ORANGE' wire. This wire should read 5vdc as soon as you start the car. When the KPtech module outputs its signal the voltage should drop to 0vdc for a brief period. It's no secrect that the Acura screen takes a while to come up, and it may be a different amount of time each time. So, if you hook the red lead of your meter to the orange wire and the black wire to ground you should be able to start the car up and watch the voltage level and see if the module is working or not.

Also, if you manually push the 'OK' button before the module automatically pushes the 'OK' button it will cancel out the module's abort function. So, if you turn the car on and ten seconds in to the 30 second delay you hit the 'OK' button the module will never press 'OK' for you.

Please contact me via PM or Email if you want to set up a warranty repair.

Thank you and good luck,

Kevin

 

The only button I know of is on the display...which would be off when the car is off. What button are you talking about?

 

There needs to be a physical button, not just a touch screen button for this to work.

 

COBRAGUY,

You have to push the silver toggle button that's located just under the display. That's the physical button that KP is talking about...

 

Yes, mine is currently only working part of the time. It's not the KP module. It is sending a pulse every time. I had a volt meter on it while I was figuring out the delay time and EVERY single time, the module worked, but sometimes it wouldn't kick off computer to recognize the input. Maybe the KP pulse is not long enough. How many milliseconds does the pulse last Kevin? 500?

I haven't had the time to take it back apart and mess with it. I was going to extend the time on the KP module a little to make sure that when the OK button on the screen appears that the computer is ready to accept the signal. I think when I set mine up I was setting it to "press" the Ok button as soon as possible after it appeared on the screen, but since the computer sometimes takes longer to boot up, the module sends it's pulse before the computer is ready. Although a few times when I was messing with it the OK was clearly on the screen for a sufficient amount of time and I saw the pulse occur, but it didn't register. That's why I was thinking maybe extending the pulse time might help.

Will

 

The pulse is actually about 750 mS.

It's interesting that it works sometimes, but not others. We could try extending the pulse a bit. Did you by chance meter the wire that you connected to without the KPtech module hooked up? The output is designed to work with a 5vdc signal (goes to ground when button is pushed). If the logic level is different we may need to make a slight hardware change to fix that problem.

 

I agree.

 

I've made changes to the output of the hardware and now I'm just waiting to hear back from Fast4Dr to confirm he is willing to test out the new board.

 

Ditto, I don't think I'd bother doing that even if it didn't cost any money! I would want it to go direct to the Trip Computer anyways

 

I guess it's to each his own, but when you get in your car and start it, do you have to turn the radio on each time you start the car or does it just come on where it was? If I had to get in the car and turn the radio on everytime it would be annoying. Same thing with the Ok button. For less than an hours work when I get in and start the car the navi comes up without having to do anything. Is it a big deal to reach up and press ok? No. But I would rather spend an hour putting this mod in than reaching up 5-7 times a day for the next five years. It's also the rebelous spirit of someone telling you have to do something and me giving them the finger, except now I don't have to use it.

Will

 

So did we ever figure out what the issue is? Fast4dr, are you going to test the new board? This is a mod I am looking at and would like to know the current status.

 

The replacement board should go out in the mail tomorrow. We just had another person order a Honda OK bypass and I sent them the new design. I'm pretty confident the new design will work, but only time will tell. Of course, if they don't work we will gladly refund everyone's money (which would be 2 people as far as I know).

 

kpierson when did my order go out,and when will i get it do you have a tracking number thank you

 

I don't handle any of the actual shipping so I'm not sure exactly when it went out, but I would guess Tuesday of this week. We ship all modules via USPS so tracking numbers are not provided (helps keep costs down).

Thank you,

Kevin

 

did you get the new part yet and if so how does it work let me know thank you.

 

you got mail let me know?

 

Yes....I got your mail and have NO idea what you are talking about. I am NOT a vendor of this product. I make custom made carbon fiber parts buddy....scroll up a bit...I think the vendor of this product is here in this thread. Ask him to help you out. I cannot do so as I did not sell the product nor provide support for said product. Sorry. I probably confused you as my SN also has a vendor designation due to the aforementioned product and I posted in this thread....but in fact...I do not sell/support this product. Thanks!

Vendor....please take this over from here.....thanks -Mike.

 

i put it in and sometimes it works and sometimes it doesn't.did you send me the update one or not i love it but only if it works all the time and not some of the time.the part is the nav ok for my 2005 acura tl

 

I'm currently working with Fast4Dr to resolve this issue. Yours was the new design, but it doesn't work any better then the old design. Our next step is to output 3 short (-) pulses each time, instead of only 1. This will give us a better chance of getting the pulse to work every time.

That will be the solution until I can get access to a TL with navi. The joystick doesn't work exactly the way we had thought it did, so some research is needed!

 

I would really like to see a picture of the Navi buttons, to get an idea of how many there are, and if they are illuminated. I would also like to know which each button is for.

Also, if possible, I would like to see the circuit board that is inside the switch housing. On the Infinitis they have a similar wiring harness like the one in the picture, but we went directly to the circuit board inside to make the connection. It works every time that way.

 

Here are a couple pictures that I currently have uploaded. I will look for more.

Would it be easier if I mailed you the buttons and board?

 

It would be easiest to test everything with a vehicle present! Any chance of snapping a quick photo of the back side of the circuit board so I can see how many contacts are on the joystick?

Thank you for your continued help with this!

 

kpierson LET ME KNOW WHEN YOU HAVE THE NEW ONE WORKING SO I CAN TRY IT?

 

I don't have pictures of the other side and it's all back together currently. Sorry. Did you find anybody else in your area with a TL willing to help?

Will

 

I'm working on him! He told me he was interested in the window module, but not too interested in the 'ok' bypass. I'm going to try and work out a deal with him though, just to let me test it out!

 

Update for all you watching this thread. Kevin sent me a new module that sends three pulses instead of just the one, since sometimes the first pulse doesn't seem to register with the navi.

I hooked up the new module and Success!! The new module presses the "ok" button with 100% accuracy.

Will

 

That is good to hear but I am holding out hope for a software patch so I don't have to tear the dash apart. I am pretty comfortable with all the mods done so far to my car but this seems the most invasive.

 

hey whats up did kevin send you a new module or just a new chip.and did you hook up the nav dvd part that you were talking a bout.let me know thank you?

 

You are exactly right, sir. This is as lame as you can possibly imagine. Meanwhile, I found the place in navi software where it displays the dialog. It will take a couple of days to figure a way to bypass it.

/AngryDad

 

you got mail let me know thank you

 

Lame? You are trying to do the same thing in the Navi software, right? I know it is more elegant to do it through the software, but until somebody figures it out, this will work for me. It's a very simple mod actually.

Good luck figuring out the navi software, nobody has seemed to be able to do it for the last 2.5 years.

Will

 

hey whats up did kevin send you a new module or just a new chip.and did you hook up the nav dvd part that you were talking a bout.let me know thank you?

 

He sent me a new module because I had already sent mine back, I have no idea what nav dvd part you are talking about.

 

As a Nissan Murano owner who's had the KP Technology Ok Bypass module for nearly a year now, I can say I love it. Every friend of mine that has a Navigation system in their car wishes they had the bypass too.

Don't bash someone for providing a solution to something that obviously, people want and are willing to buy and install. I installed it in my Murano and never looked back (or at that damned Ok dialog either).

If you find a software solution, good for you, but there's no need to call the solution "lame". Show some manners.

 

So your saying you could program the unit so that when I press the ok button twice quickly, it would either ground or engergize that extra wire? That could be used as the switch for flipping over to a DVD or TV input. That would be awesome. No need to mount a switch anywhere
