AVIC-Z2 Pre/Post-June Bypass Files

READ THIS ENTIRE THREAD BEFORE PMing ME OR POSTING A QUESTION. IT IS EXTREMELY LIKELY THAT IT HAS ALREADY BEEN ANSWERED.

Ok, let's start this off by saying that you take responsibility for your own actions, not me or Pioneer or this forum shall be held accountable if you watch a movie and plow into and kill a family because of this functionality.

That said, a big thanks to a couple people on this forum, without whose help would have made this impossible (you guys know who you are).

-----METHOD 1 (can be tricky, but techies might want to know how it works)----------
After some extensive testing with the Z2 images and the CNDV700HD update disc, I've found the files responsible for allowing or disallowing the 2-wire bypass. To use these files, you will need to already have a Z2 (or Z1 with a Z2 image....hint hint), and have your hard drive unlocked. Simply download these files (link below) and overwrite them onto your SDATA partition (only overwrite the ones included). Like the Bluetooth update for the Z1, a zero-byte file called PRG.FLG in the root directory is the marker that the other files look for to allow the bypass. After you copy these files, a low-level reset is required (the recessed button next to the "face-down" eject button). Some of these files are already updated on the June version of the software, but to make this a one-stop-shop, they're included again for you anyway. Thus: This will work on any of the known Z2 versions.

-------------------METHOD 2 (assed out easy)------------------
CDROM ISO!!!!
1. Download this 30MB file: http://www.megaupload.com/?d=4T5MBJL7
2. Burn to CD or DVD as an image, not using built-in windows burning.
3. Insert in Z2, press Map, and run the update! (e-brake must be applied or wire grounded
4. Press the recessed reset button once, and your Z2 is now 2-wire bypassable.

This is for Z2 UNITS ONLY!!!! This will not upgrade your Z1, and actually might leave it unusable, as it relies on some firmware that isn't installed. Turns out the update disc was pretty easy to cut down to just the files needed to update for the bypass.

Enjoy!

So this means we have to use the sticky about unlocking the Z1 HDD and pay $42 from the other sticky so we can copy these files on there, and use the Z1 "grounding 2 wires" bypass correct?

Since the forums seems to have found a bypass I'm thinking about buying a Z2 now, but just want to make sure.

Yep!

Hyperite...GREAT job, This is what I and most likely many others had been looking for...one question what about the files in PRG0? from what I have viewed from the other systems( Z1 early and after blue tooth and Z2 early), those files had been the same as those in PRG1...any comment...should we also insert the DATA folder into PRG0? Is PRG0 the folder that is used when the system resets to factory settings? wheeoo that's alot of questions for one post I'm sorry you don't have to answer them all if you don't want to. but this is rather exciting.

[Hyperite]

They are the same files, but they aren't referenced at all, not even after a reset. You can overwrite if you want, but it shouldn't matter. Also, this is entirely a moot point as I just updated my post with an easier way

Very nice, thanks Hyperite.

So method 2 means I don't have to buy the HD adapter and go through the HD unlocking process etc right?

Thx again

Correct, you do not need to remove your drive at all.

You are the man, thanks for making this post and posting the ISO

Hyperite- Thanks for your help, was there anything else on the update disc relevant to Z2s?

This happened with the bluetooth update disk. Take the disk out and put it into a PC and try to copy all the files from the disk into a folder. If it works, I don't know how to help you. If it fails then it's a bad burn, if it's like the bluetooth update disk you should be able to reburn it and stick it into the drive and complete the update with a new disk.

will this work for a mac too??
