Got my z2 installed last week and i think i saw the manufacturer date of after june 2007(cant rem) on back of unit bfore the install. I think the bypass was done by installer cause the message would come up that break lead is connected improperly pres ok, somemessage like that. But the problem was that when iwould go over 10mph the dvd will stop playing. You can still hear the sound but cant see the video. Anywayz after seeing this thread i thought i needed to install the update to make it work. So i used the method 2, burned the iso, put in the z2 and it went through the options of updating, and then copied the files to the HD. After which i press the reset button, but now it just frozen on the Pioneer main screen that comes after u start the car and none of the buttons works and touch screen wont work either. When i put a cd or dvd in, i can hear the music and sound but nothing else and only the volume up and down key works. How do i unfreez it so it goes back to the normal screen. Plz help...

It SOUNDS like you didn't let the update finish. When it said "remove disc and reboot" or whatever, did you instead press the reset button? Because that will remove the queued files to be transferred to the EPROM on the reboot. Need to let it complete the full cycle before pressing reset.

Anyway, if that's the case, your options are still guesses: you can try running the update again, but I have doubts that'll work since the filesystem doesn't seem to be active if it's hanging on the splash screen. You can try a full system reset (search the forums for how to get into the service menu, i don't recall). And your last option would be to remove the drive and reimage it with the one available from the forum.

I downloaded the freez firmware update from pioneer's website and installed that but after finsihing the install, it gives the error message that the update was not installed correctly. After turning it of and on and doing couple of resets, However now the system is working back again. But I dont know whether the update was done or do i ahve to do ur method #2 update which is the 30mb file Again. Although all the functions on the z2 are working, i still lose video after going over 10mph. Do this method #2 update(30 mb file) HAS TO BE INSTALLED on z2 in order to make the system fully operational with dvd watchign no matter how fast i am going. The installer did said he installed the bypass wires and i had to update my system so should i try it again and see if that work?

thanks for ur help

Another quick question too, to do ur update #2(30mb file)...you say E brake must be applied or wire grounded. In my situation since the bypass is done, I dont have to apply the e brake? Cause last time i did apply the e brake and i dont know if that cuased the system to hang, since the wire was grounded via bypass and ebrake was applied too at the same time. Plz let me know that too..thanks

Sounds like you didn't burn the freeze fix correctly. Either do it correctly, or try the 30mb file from this site. Both should make your deck bypassed if your installer did it right

Thanks for the help. I'll remove the unit and check the ground to the bypass pin on #2 connector soon.

I am a little confused as to why the system reported the update had been previously done. I assumed the system had to be update so the bypass could work. The bypass is a hardware and software affair isn't it?

The confusing part to me is I am not totally sure the software part of the bypass is done. Why would the system report it had already been updated?

I was able to get the ground wire inserted in the #2 connector pretty good. I followed Hyperite's directions and with the photos it was simple. The ground could have came off but I doubt it.

In any event I'll pull the unit out to check the ground.

Check your grounds and that the pin is firmly seated in the 'bypass' hole in the harness

 

I installed an August 2007 build AVIC Z2 today. I grounded the E-brake wire and removed a unused lead from the pioneer harness to add to the empty space on connector #2 and grounded it as well.

 

When I tried to update using the image files I burned the unit told me update was already done.

 

Of course I do not have DVD play capabilities once the truck is moving. I assume I lost the ground on connector #2 but if some one here could check my work so far I would appreciate it.

I pulled the head unit out the other day and checked the ground to the bypass pin on connector #2. It appeared to be seated well in the connector but I took the time to strap it in such a way as to keep it tightly in the connector.

Now I do have DVD play capabilities while moving! The AVIC-Z2 is great. It is THE way to enjoy sound while on the road. Nothing I have ever used intergrates XM and an iPod so well. Pioneer has got it right.

Thanks for the help and thanks to Hyperite for starting the thread.

Just finished my install.

Did the two wire bypass, put the CD in Hit map then reset. and it works 1st time.

So far so good.

Thanks for all of the help.

Worked perfect on my April Z2.

Did the two wire bypass on a Sept unit and it's working great.

Did the 2 wire bypass on a Sept 07 unit with no software update and works great.

Thank You All!

same october 07 2 wire and it seems to work

ya I just got the june 07 unit, installed it today with bypass already done, but it didnt take the update cd. when i put the cd in, it says update already done. press okay.

but it works while driving, plays dvd, and address search works fine too. so wat is going on

The software change took play at some point during June production. Some June decks need it, some don't. Apparently, yours didn't

Ya i think so, but i have a question, how would i check that i have this updated firmware, because even though i am not getting any nags error, messager or nothing, but in the information tab, i have only 3 out of 8 buttons that i can choose, like traffic setting, XM, but all the others are not avaliable, like other traffic buttons, favourats, set my favarots, so is there a way to enable those as well

Ya, pay for the XM NavTraffic service

My Z2 is now bypassed! Thanks Avic411.com; this site is the shiznit! My experience with the bypass:

I was originally concerned with the 2-wire bypass. I didn't have the installation guide because the installer forgot to put it back into the box. Once I got that, it was easy to see how the lime green parking brake sense wire tapped into the brake switch wire. I cut the brake sense wire about 12" from the back of the head unit. I then dead-ended the half going down to the parking brake switch and taped it out of the way till I go back in and remove the entire wire. I then joined the upper 12" of the brake sense wire coming from the head unit, with the relocated phone mute wire. Then I spliced both of those wires together with an external ground wire that I ran to a good ground.

The above wiring, combined with the firmware update allowed my Z2 to access all menus and watch movies without the brake applied. However, as soon as I started moving, I'd get the pop up telling me that the brake wasn't set properly. So I went back in this morning when it was light outside and pulled out the connector 2 plug. Sure enough, the phone mute wire had slipped back a little and it's pin wasn't even with rest of the pins. I had noticed when I removed the phone mute pin with the screwdriver (I used a 1.0 mm precision slotted screwdriver) part of the little tab that holds the pin in the connector broke off. As a temporary fix, I zip-tied and taped the wire harness in a way to force the pin forward into the connector-I'll probably end up super gluing the wire into the connector as a more permanent fix later on. Moral of this story; be careful removing whichever extra pin you decide to use.

Once again, thanks to everyone who posted their problems and solutions. I've added a Rapidshare.com mirror for the update iso image here:

I did method 2. Put the cd into the drive, pressed map, and after its done updating. It says, old version updated, please update new version. Or some crap like that. Clicked "OK". reset the system, and it works perfectly. But after i turn off my engine or some time goes by, i have to redo this process. Is this normal? Or it this supose to be a one time thing?

Sorry, just to clear things up. When i put it in cd, it says this is the old version, u need to put in new version to update, so all this time i thought it was already updating. Weird, because it works after i reset. And the reason why i keep having to do this is because somtimes the navigation detects a brake lead, which doesnt allow me to watch dvd while driving. Still wondering if this is supose to happen? Resetting the system all the time can be anoying.

Sounds like you didn't do the 2-wire connections...

For the two wire bypass that you have to ground the two wires...mute and green parking...do those have to be grounded separate than the other grounds?

No

so I am going to add the black ground from the headunit to the yellow and green which all goes to the black harness ground? It just seems to easy but I hope that's how you do it

Ok.... To start things off I am a newbie at this. I just bought the avic z2 and am going to perform the bypass. I have already done the 2 wire bypass on the unit and am now ready to install the update. My question to anyone willing to help is do I burn the hack as an .ISO file. This might sound like a dumb question but like I said.... I am a newbie.

Thanks in advance!

No, the ISO contains many files. It's like a ZIP file that the burning software knows how to interpret. You'll need to burn it as an image with Nero or Magic ISO. Confirm that you did this correctly by looking at what files are on the CD after burning. Should be a bunch.
