Attempting to update my brand new Pioneer AVIC-8000NEX, I have run the SyncTool on the device, Then run the Naviextras Toolbox to update. The Toolbox says that the update completed without errors.

I have yet to do a complete "cycle", so I have not had the same experience... yet.  I can think only two possibilities, though: 1) IIRC, you have to turn AV off, and 2) someone posted in another thread that Pioneer was aware certain units would not update, and they are working on a patch (ETA TBD, as usual... )

Thanks for the response. I will try turning the AV off today and see if that helps.

The same thing is happening to me on my 8000-NEX as well. Been in touch with Pioneer support, who have been useless.

No go here. I tried with AV off. I've also tried leaving the car on and not restarting the nav while I updated on the PC.

Pioneer responded to me today. They stated that it is a known issue and that they are working with Naviextras to fix it.

I wonder if they will ever actually do something. Pay $1,200 for a "top of the line" headunit, and then this. Lol.

Where are you guys seeing a map update for the 8000NEX?

NaviExtras Toolbox software.

Do you see this on the website or do you have to download the software?  I'm looking on naviextras.com and I see the AVIC-8000NEX but it doesn't show any extras at all.

You have to download the software. Don't worry, its a moot point right now anyway since the update is broken. 

Naviextras Emailed me this morning, asking for a zip file of the synctool folder.

Maybe they will actually help.

That's what they did for me too. Nothing came of it - just got an email today letting me know its a known issue they're working on.

Well at least we know they're [claiming to be  ] working on it.

The downside, even if they get it figured out, is it may be on the HU side of it and require a firmware update. Pioneer may wait for more issues to resolved before a firmware update is issued.

Which USB port are you using for the update, and are you doing it through a cable or are you plugging the USB stick directly into the back of the HU? The way I have mine installed, USB-1 has a lightning cable connected, and USB-2 has a M-F USB cable running to the glove box. Given the finicky nature of what's plugged into USB-1/2 if/when CarPlay is running, or if (attempting to) use AppRadio via HDMI/USB, I wanted to make sure there's not some unwritten rule about which port has to be used. I have a ticket open with Pioneer on this as well.

I have tried every variation and combination I could come up with. 
Today, Naviextras emailed to inform me that they are now aware of the issue, and they have reproduced the issue.

They also assured me that if fix comes after my 45-day window for free updates that they will honor the update and insure that I get the current maps. 

Lets hope they commit to that for all of us. I'm having a hell of a time getting pioneer or naviextras to commit to anything. 

2 days ago I got the free update to complete on my 8000, I then purchased the paid update to bring it up to 4Q 2013....error initializing

waiting for the fix aswell

what firmware is on your 8000?

what firmware is on your 8000?

the latest 1.08

Same issue.  I contacted Pioneer tech support who seemed utterly unaware there was an issue with this update.

Pioneer is opening a ticket for me.

I heard back today that the issue was fixed, and I can confirm that I was able to install the update. NaviExtras updated the installable package.

I was able to finally finish the 2013 Q4 update this past Thursday night via the usb cable.

Kinda lame that 2013 Q4 is the most up to date Pioneer is making available.

Just want to confirmed that the map update finally worked on my avic-8000nex on firmware 1.0.8 . I too was getting the initialize error message but after readng the post that it works i decide to try it again and it works.
