Sorry for the delay, I have been busy the past few days.  I can confirm, though, that all that was needed was the bypass.  It has been working for a couple of days no without any issue.  If this gets patched in the next firmware update, then I will tackle the grounding then.

Also, drenyce311, I am aware that the wire states "parking brake wire", but thank you for clearing that up for me.  That is kind of you.

My generocity is for everyone. I am here to help our community. Thanks for the kind words.

New guy so I would like to start off by saying 'thanks' to all those who have posted regarding this issue. You all have been a HUGE help! Without you, I would be completely bald. . .

I had the AVIC-5000NEX installed in a '07 Dodge Ram replacing the OEM nav system. I go to pick it up after the installation and see the green parking brake wire laying on the floorboard. "Just ground it and you are good to go" they tell me. I asked why they didn't. They reply they can not do it for either liability/law reasons? Never heard of this. Whatever. Easy to do in any event, although connecting to the parking brake lead was going to be a PITA. . . .

On the way home I have to listen to 'her' letting me know that I was speeding. That was absolutely annoying. . .!! I tried to set this in the Map Settings and it is greyed out unable to select it. . . What the hell? I spend the next two hours, resetting, powering up/down, researching to no avail and then it dawns on me, the green parking brake wire??? No, it can't be. . . So I call the installer, who says that shouldn't be the issue, but speaks to the actual installer and comes back to me and says you need to ground it. OK, so I do.

I now then am able to adjust the Map Settings turning the speed visual/audible warning off. Success! BUT, upon startup of the vehicle I get the prompt about the parking brake cable not being correctly connected. I dismiss it and determine that when the vehicle is stopped, I am able to access these Settings. When the vehicle is in motion, they are again greyed out. So it appears that in conjunction with the parking brake, the unit senses the vehicle motion in determining what can be accessed or not when in motion.

I certainly do not want to dismiss that prompt every time and a quick DuckDuck Go search brings me here to AVIC411! I immediately find this topic and the software bypass and activate it! Everything in the world is right now! Well, almost right. Where the hell is the CarPlay update already Pioneer. . . ?? Again thanks and if you have any questions, let me know! A great unit by the way!

ground the parking brake green wire after to having to incessantly listen to her letting me know that I was speeding all the way home!  Geez, enough already!  I remove the AUX cable they installed, thankfully not charging me for it, and a few other minor things.  Start it back up and get the prompt about the parking brake cable not being correctly connected.  Dismiss it and FINALLY get to the Settings to turn the speeding prompts turned off

Does the parking brake have to be grounded? I called a shop today to schedule a date for install and they swear to me it doesn't need to be grounded. I told them it does. They were adamant.

It has been reported by many on this forum the the software option detaed on this thread is all that is nessisary.

The software option doesn't work on the European versions (F60DAB)

Then ground the p brake wire.

I have, that works fine, just pointing out that software option isn't always the answer

nex8000 install today - bypass working like a charm. thanks all

I tried this on my new 7000 and I still get the caution screen upon entering the map function. It doesn't happen if I turn the car off then on but if some time has passed, still appears.

I have successfully applied the supposed hack and even tried it set to on and off, same result.

What am I doing wrong?

Probably redundant but just did this on my NEX 6000 and worked perfectly, I didn't try without grounding the brake wire, I just grounded it, put the unit back in place, did the AV/Off/12 second press procedure and got the Set On message right away. The change seems to be permanent too. Thanks to the original poster!

I have gotten the "parking brake not connected properly" message a couple times, probably once every two weeks. But everything is still working normally.

Why would you ground the PB wire and do the software bypass? 

The bypass on AVIC units has always been to ground the parking brake wire along with another proceeded to properly achieve the bypass so it is by habit that this is stil done. Quite frankly I feel Pioneer may eliminate this "software" bypass with the CarPlay update so this is probably not a bad practice sense it will likly be needed if they do change the bypass.

That is by design. You will always get the Caution screen everytime you start up the car.  My OEM navigation in my truck had the same caution message every time I went into navigation mode. There is no way around it unless your an amazing programmer that will hack it and eliminate the code.

I never knew about this trick, while it's been stated it does not work on the 4000NEX...so I got an eBay bypass so I hope it works (only $10) if not, I will have to do the parking break ground thing I'm thinking.

I ended up using a relay because I thought it was a cleaner solution. I also used the software hack as well. Works great.

for the 4000NEX the bypass relay will work.

Oh so this bypass doesn't eliminate that screen? I must have just assumed that's what it was for. Thanks!

The bypass is to view videos in your vehicle while in motion. (NOT ADVISING TO DO THIS). But comes in handy

Ah, thank you again.

Does not work on 4000 but a switch to ground does the trick

The Microbypass devices work just fine for the 4000.

I have a 7000.  The installer grounded the parking brake wire and installed a bypass relay.  It worked for a few minutes.  Then the 7000 sensed motion, ostensibly via the gps unit, and the restrictions returned.  Applied the procedure for software bypass and it works.  My passengers can now operate the navigation unit while I am driving.
