I have a Z2. Effectively did 2-wire bypass and ISO update. DVD works magnificently, BUT my navi is all screwed up. It shows me going at a 45 degree angle away from my current direction and only shows half speed. GPS antenna signal is high, VSS speed sensor is connected and showing a signal. The unit will update my current location approximately every 10 seconds (GPS?) but still shows me going off course between updates.

 

Also, it seems as though the unit is only showing me going about half the speed I currently am. Only had the problem since I updated. Any suggestions, besides the obvious resetting the system and checking grounds (which I've already done). Thanks guys!

I just had this problem too. I reset factory defaults and reset the 3D calibration.

Go to the source menu and change the setting for 'Rear Monitor'

 

I have two headrest monitors that worked perfectly before the bypass. After the bypass (which otherwise worked great) they say "no signal" and I can't find anywhere in the Z2 to re-activate them. Any suggestions????

Still nothing on this. I can switch through all the Source options and the headrest monitors are stuck on No Signal. I thought maybe the software update caused the Z2 to forget about the monitors and it has to be told again that they're there -- I had to do this with the backup camera, for instance. I guess there's nothing like this with the headrest monitors?

Just wanted to drop a line to say thanks for figuring this out guys. Also I just bought my Z2 last week and when I put in the Update CD after performing the 2 wire bypass, it told me the update had already been applied and everything works like it should!!! This goes to show me that Pioneer must have caught on to the update and started releasing new systems with the update already installed. Thanks everyone for your comments which also help answer any questions people may have.

I have a Z2 and the pic in the two wire mod is for a Z1. Do both units look the same?

Yep

Yes both harnesses are the same. Harness 2. when you have the clip facing up, the right 4 spots on the harness are blank 2 top and 2 bottom.

So the pic represents the end result? And All I have to do is remove the yellow and black cell phone mute wire place in the connector as shown and it's grounded? (I don't have to ground the yellow wire?)

and since my Light green parking brake wire is already grounded the last step is load the software?

Correct the picture shows the end result. The yellow wire in the picture is the wire the person chose to use, I used the mute wire as well since it fit nicely in the connector and locks in place.

Yes run the update process and your good to go.... Don't forget to hit the reset button lastly which is what I read most people are forgetting to do.

My z2 was made march 07 what steps should i follow for the dvd playback bypass . Also i am having the freeze issue and cant seem to download the firmware upgrade with any success (HELP). Pioneer is sending the disc.

Download and burn the 30 meg file from the sticky at the top of the page. Then do the 2-wire method of grounding

Put that disk into the Z2's drive and do the update. Then ground the 2 wires.

whtcrxghst, normally I would never disagree with you. But he is having trouble downloading the iso from the pioneer web site, so downloading the 30 meg one from the sticky might also be problematic. And Pioneer is sending him a disk to fix the freeze issue he is having trouble with... this will also update the unit for the bypass with the 2 wires. So just wait till that CD from pioneer comes in and update your Z2 and then ground the 2 wires. Don't bother with the 30 meg iso on the first page.

Thanks for your reply ill wait for the update disk and add the two wire method.

My bad. Forgot the Pioneer disk does the bypass too

Ok Last one maybe. Does it matter if I do the ground first or load the software first?

Gracias

No, but you will get the parking brake error message if you do the ground first. Doesn't hurt anything, its just annoying

I did the wire bypass with no problem. Burned the disc and can view all files on cd in windows explorer. Insert the disc, then it says it has already been updated. I just bought the HU, nothing has been done other then the wire bypass. Is it already installed?

Having Problems burning the disc I"m using Nero

Thanks in addvance,

-------------------METHOD 2 (assed out easy)------------------

CDROM ISO!!!!

1. Download this 30MB file: http://www.megaupload.com/?d=4T5MBJL7

2. Burn to CD or DVD.

3. Insert in Z2, press Map, and run the update!

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!

Link works fine.

The Z2 Bypass download worked like a champ!! Quick and easy, assed out easy!! (method 2)

I believe i have a real problem....

First let me say i had done the bypass succussfully on my Z2 unit before the "freeze" update was re;eased by pioneer. Now many people had success with this while i did not. After trying to install the update the unit says the update failed and rendered the unit useless, literally. No reset would enablethe use of the unit. If i had a copy of the harddrive i'm sure that would have done it but in any case i sent it to pioneer and they "installed the Freeze update" for me.

Here's where the kicker gets in, now the unit works wonderfully and doesnt freeze;, however my bypass is lost. I thought i'd try to download the ISO provided as i did the last time. After putting the disc in, unit says update already installed.I have triple checked my connections and the mute wire i used for wire #2 is locked in the connector as it was when the bypass worked. i have reinstalled the grounding wires to a differnt place where i know they are grounded and then back to the origina position where it worked before sending it to pioneer.

Is there anything i can do? Anything you suggest? I read most of the time it is problems in the grounding of wire #2 i'm quite confident that this is not the case. I have pressed the rest button in order for any changes i made to take effect but the parking brake error message pops up.

I looked at the OS version number and found 2.0000 i thooought i rembered seeing it at something other than 2.000 is this wrong?

thanks, I will down load it again and let you know

Double replied time

Thanks Hyperite, but i can't get it to work. After I insert the disc and press map is says "CD ROM inserted" and nothing else happens. Am I missing a step?
