Disable navigation saftey feature 2007 G35

[smithm7]

I'm new to the forum, so I hope I am posting this in the right location. I am interested in trying to disable the safety feature on the Infiniti G35 navigation, which prevents programming while the car is in motion. I have a 2007 G35 Sport 4DR. In addition, if I could enable the screen to play video while the car is in motion that would be a plus.

Fairly easy to do. If you go to the the FSM (factory service manuals) here you will get all the information you need.

What you are looking for is what happens that disables the ability of using the system properly. While I don't believe in 'programming' it in the sense of adding in text and so on I do believe in being able to 'use' it instead of playing with work arounds.

Basically you need to consider that when you speed up from a stop the system features becomes disabled, so speed sensing is what is killing you.

You can do this in a couple of ways. One is a kit which does a couple of other things such as push the enter button for you, another is simply bypassing sensing of speed via a toggle switch, still another simply doing the same with a little extra smarts using a simple timer to restore normal function. The normal function is important as it influences your position sensing between GPS updating. That is there is a motion sensing device, a sort of electronic gyro that knows which direction you are traveling and keeps the unit updated. It then calculates position based on your last position. In short you need to reestablish the speed signal.

As far as the video goes, I would not disable this feature except for the addition of a car computer type of use for adding gauges, etc. to the system. If you are simply doing it to watch video, then I consider that a real no-no and so will the cops. The info is in the FSMs.

I have not used thier products (yet) but after doing a BUNCH of research they seem quite reputable...Good luck

I recently installed the HKS CAMP2 in my car.

For those that do not know, the HKS CAMP2 is a digital gage display that is capable of monitoring various engine parameters using either the factory sensors, additional sensors or a combination of both. This is a screenshot showing 6 gages on the factory LCD:



In order for the gages to be displayed while the vehicle is in motion, you have to:

1) cut the parking brake signal to the head unit and ground the side coming from the head unit. No, you will not get a parking brake warning light in your dash because this is just a signal to the head unit.

2) put a 2 position switch in line with the vehicle speed signal. When the switch is closed, you will have normal navigation (if so equiped) function. When the switch is open, you will be able to view your CAMP2 display BUT your navigation will not refresh fast enough. You can locate the switch anywhere convenient.

To determine which wires to cut and splice, here are the pin connections for the back of the three head unit configurations available:

It looks to me like if you wanted to you could remove the multifunction switch and install a relay that would disable the speed sensor and brake when the aux was pushed (or any non-nav related switch for that matter). Reenabe it when any nav related button was pushed. Some consideration would have to be taken for something like Info, status, etc.

I would like to see using another connector so you would not have to cut the original.

Thanks for the information

Thanks for the info. Btw where did you get your body kit?

Thanks for the link. Looks like they have a lot of great things. I am curious if anyone is familiar with them reagarding quality and ease of installation?

A relay could certainly work, but in this case, the ebrake signal serves absolutely no purpose except as one of the lock outs to the nav functions in the HU. There will never be a reason to reconnect it.

So that leaves only one wire (VSS) that really NEEDS a switch for proper nav function. And this wire may not even be needed if you do not have nav. A relay would be extra work in this case.

I thought about making a pigtail as well, but that would require a damaged HU and a harness for donor connectors. The HU has proprietary connectors.

Here is the back of the HU:

I don't have a body kit. That's the factory body work.

I also have the KP Tech module in my car. Very straight forward installation if you are comfortable with automotive wiring. You'll still need to cut the VSS wire though. With the KP Tech module, you operate the relay from the OK button. Another bonus with the module is that it also auomatically presses the OK screen on initial start up.

Can the pins be released from the end? While the connector is proprietary the pins may not be. I have done this on many other connectors which allow not doing any cuts so you can restore to original if desired.

You put the relay or switch on a single pin connector with a short wire with another pin on it that then fits into the original connector. The idea of the relay is that you can either have it work off of a pushbutton that will restore the speed signal after a set time or off of the multifunction switch, any button pushed that has something to do with normal nav functions (such as map) would then reenable the speed signal. To me while the 'ok' is a little bit of a pain I don't really consider that much of a worthwhile project.

However in the case of the Nav I am not so sure there isn't another solution. I have noticed that without the car running, such as if I am simply programming it I don't have to push the 'Ok'. Is there something we are ignoring?

The OK button as used in the KP Tech module essentially triggers a relay. The module can be programmed for timed operation after the OK button is depressed, or latched so the OK button has to be pushed each time you want to switch between nav operation and AUX operation.

The ideal solution is to go directly to the nav screen. I haven't had time to mess with it, but it essentially takes an RGB input. If there is a backup cam on the car, I believe the LCD actually has multiple inputs.

What I am referring to is that if the car is not running and I want to program the nav I do not have to press the OK button to clear the warning screen first. As soon as I start the car I do. This indicates to me that just maybe there is another way around the OK button than simply simulating pushing it.
