I had my CN-NVD905U professionally installed by GeekSquad/Best Buy. I am very, very happy with the system, notwithstanding the high price tag to buy map updates, and the disabling of critical functionality unless the parking brake is set. Unfortunately, GeekSquad would not do a bypass for me, so I'm left to my own devices for getting this done.
I have no interest in watching DVDs while I drive, but I find it utterly obnoxious that I can't make even minor changes or selections to my navigation while I'm driving in safe areas.
I have read on this forum and some others that one can simply "ground" the parking brake cable to bypass this safety "feature".
I have a few questions:
1. I have heard that the Strada has built in speed monitors that will ensure functionality is disabled even if the parking brake cable has been grounded. Is this true?
2. Will grounding that cable have ANY other negative impact on the operation of the system, or my car? If it will, I'm not against doing this, but if I'm going to go ahead and do so, I'd like to know what to expect--the good, the bad and the ugly.
3. How do I do this? I'm not a mechanic or an a/v engineer, so I'm hoping for some guidance on how to find the cable that needs to be grounded, and to what I need to ground it to.
Thank you,
Dan
All you have to do is find the cable that labeled side brake ( I believe it's green) and attach that to any metal part of your vehicle and it should by pass the safety feature.
I would suggest not ground the cable because as you know that a signal will travel the path of least resistance. you could interfer with your ecm and that is a whole different set of problems that will cost you a ton of money to fix. there is a reason for the safety features. I know it's a real pain, but the devices were designed this way so that the liabilty issues would never come back to bite them. I know this is not what you want to hear, but please rate the solution anyway.......thanks
well i am a mechanic for a living and the sensors as far as speed are interfaced with the ecm. they cannot be circumvented for any reason. the navigation unit is piggybacked onto the ecm and uses the parameters of the speed sensor on the vehicle to send a signal to the unit. by basic fundementals trying to tamper with the ecm will not only effect the performance of the vehicle but the nav unit as well. as far as the geek squad is concerned they may know how to install a electronic device to a vehicle but they have no clue as to what a nav unit piggybacked to a ecm will do. the ecm runs everything your vehicle does. I can use a scan tool and change the settings of the sensors however i still can't circumvent the safety features in a nav unit. and there is no one who will either because it just can't be done. this is food for thought. don't be mislead by alot of what you might read on this. my purpose is you give you the best advice that is avaible. beware of so called experts that tell you that electonics can always be tampered with and then installed on a vehicle.one more thing the DOT and the Traffic Safety Board do have mandates as well as what the the URL(UnderWritersLabatoryhave stated when they approved the use of these units in passenger vehicles
it is unfortunate but there are quite a few experts here that are not experts they assume you will buy the solution hook line and sinker when in fact they have know idea on how to solve the problem. when you asked for a detailed response i gave it, usually the ones that won't are the ones to watch out for. do me a favor and rate my help to you it would be appreciated... thanks
what most people don't realize is that most models have a cable that operates the brake itself, however on the electronic side of it there is a micro switch that is activated when you press the pedal same as the brake pedal. you also have antilock brake modules to contend with. i have installed lock out valves for brakes on trucks that come equiped with aerial lifts. so i do know quite abit about what you can and cannot do with safety issues on vehicles. if there is anything you need help with as far as cars trucks or heavy equipment just let me know by clicking on my user tab.

Even the government hasn't intervened to mandate that vendors of navigation systems make these "safety locks" on their products. And you surely well know, there is only one reason the system was designed this way. That sole reason is so that Panasonic can mitigate any legal and insurance liability if someone crashes their car while using the navigation features.
So yes, you're right, it's not the answer I'm looking for. While I appreciate your taking the time to read and respond to my original question, I would appreciate a more direct response to the questions I posed, and let me decide what is safe operation and what is not.
If you have details as to what specific kind of interference with the ECU one could plausibly expect, that would be a productive start.

Thank you for the detailed response. It doesn't sound promising, but I am curious because quite a few references on THIS site mention that it works fine when the parking brake cable is grounded as a bypass.
