k, so new to the forum name is mike live is MS got the z2 in now an 07 F150. It was working, kinda in an 04 that i sold a week ago (it would catch it and i'd have to reset periodically), i had the z2 moved to the new truck and the system notices movement everytime, it has to be sitting still to work. that being said used the bypass as posted here to update the first time, thought it may have been lost during the transfer but when the new disk is inserted it says the update is already there any ideas ???

Hey guys. I flashed the Z2 with that unlock software, and I need to know if this is normal. I haven't done any wiring changes whatsoever, but the locked features now work anytime the car is in motion as long as the EBRAKE is on. I can barely push the ebrake in so it just clicks and then all the features unlock. So is this normal? Do I just need to ground the ebrake wire now??? Speed pulse has never been connected. I was told it is digital on the Mercedes and you need some expensive converter to make it work.

2-wire bypass has been done wrong or has come loose

Its probably still calibrating and will start cutting off once it has finished. Do the 2-wire bypass described once it does

OK, i read as much as i could, but 39 pages is a lot to read!

I just got my Z2 yesterday. had a great audio place install it. they even installed a toggle switch (suppose to emulate the ebrake). Im not sure if they did the 2 wire bypass, but i assume this is what they did.

when i check the config on the deck, it says hardware verison feb 2007.

the box the deck came in says oct 2007.

i tried to do method 2, the software/firmware update, and when i did, it said it was an older version than the current one in the deck.

the toggle, from what i can see, on the ON position, frees up some options that arent clickable. so i assume this is the ebake emulator ON. the issue is, once im in motion, it turns off the DVD. the audio from the DVD is fine, but it says that viewing is prohibited..

I even did a reset (front panel next to the eject button). all that did was freeze the DVD, and so i had to pop it back in.

Any help is appreciated. thanx..

also, talked to my installer/friend. he said that he didnt remember seeing any empty wire holes on any of the wire harnesses. am i facing maybe one of the newests z2's???

toggle switch won't do it, there is definitely a blank space to put the second wire for the bypass.

First like to thank everyone for finding how to bypass the Z2.

I have a little problem since I downloaded the bypass. I had a friend download the file on his Mac, My z2 updated then said it was done updated then it said it had to reboot. It rebooted and said starting pioneer start up on left top of screen. Then the screen went blank, I tried and reset unit nothing happened, unpluged power nothing happed. So I took the firmwire update disc I got from pioneer and inserted it. It did the update all 92 then right before it was finished it said update failed.

Now my Z2 just says "starting pioneer navigation on left top of screen and then flips to a screen that says starting update and then says update failed. then satrts over again.

Do you guys have any ideas? Thanks for any help

Sounds like you fucked up the filesystem by loading two incomplete firmware updates. If it says it's continuing the update before it gets into the map application, it should do the same without any disc in. Empty the CD player, push the reset button and it should finish up the second part of the update. If it boots into the map, put the bypass disc in again and see what it does. If it all goes for broke, you might end up having to pull your HD and reload the image, or sending to pioneer.

I've read several post about the Avic not taking the "Freeze" update very well.

From what I've read....persistance and crying seems to work.

Thanks for the quick responds....

I tried everything, from reseting unit to pulling power. (Not tech so don't know what you mean by messing with HDD) Still says starting Nav on left hand side then goes to the update system to system update failed. then starts over again. Talked to someone from pioneer and they said I should try and do a hard reboot. Which means to hold reset when vehicle off then turn, then start vehicle then when start up screen comes on hold map button. It should say clear files then you can confirm it, but my unit will not allow me to get to that step. Any one try this before or heard of it? Any help is better then where I'm at now. There to get fixed before big trip this weekend.

Downloaded the file. Hit map. Hit ok to update, and then it says "update file has already been updated". When I drive it locks up. Just had it installed a day ago, and the installer said he did the 2 wire by pass already. When I start it up sometimes it says the e-brake is improperly connected.

Is the 2 wire update done wrong? Did they chnge anything? Am I just not doing it right?

Thanks in advance!!!

2-wire bypass done wrong. thanks for reading the thread...or even the last page.

main question was that the new ones are coming with the update already. Read a lot of this forum, and didn't see much on that.

Pulling the deck back out... pulling out sucks!

Thanks!

my deck was labelled oct2007, so one of the newest ones. i went to pioneer to get the info to check what i had. so according to my decks info, i got the 2.14 update, which makes sense why the deck wouldnt let me update the firmware.

im waiting for tuesday so my car audio installer can tryt he 2 wire bypass.

The bypass works and I get no ebrake messages, but the nav gets lost quite often. I had the installer unplug and replug the gps antenna because signal strength was not very good. Now I usually have 2 green bars and plenty of orange satellites. When it gets lost I check signal strength and I lost all green bars and most satellites. Any ideas? Also he swears the VSS wire is wired correctly, but when looking at speed pulse in the connection status menu it never comes off 0 while driving. In 3D calibration speed pulse is always 45. From what I read that does not seem correct. I did not reset the unit after I installed the freezing firmware. Should I start with a soft reset or did he do something wrong? Thanks.

Try resetting, but sounds like it's not connected properly. VSS shouldn't be 0 when moving. Where is your GPS antenna located? Clear view of the sky?

At first on the dash. Now it is just above the front windshield. So yes clear view of the sky. If the VSS is not connected correctly would that cause the nav to get lost often?

I did the by-pass to mine. The navigation's functions are available when the vehicle is in motion but the DVD's picture won't play. I also get the parking brake message at start-up. I'm going to try the one click of the parking brake thing to see if that does anything.

Then you did the bypass wrong. Re-read the instructions and give it another shot

Hmm, VSS shouldn't cause it to get lost, but if the antenna isn't getting strong signals from the satellite, that would do it. Fix both and you shouldn't have a problem.

thanx for all the info. the hack works on the latest firmware(2.14). the picture to the 2 wire bypass is just a little miss leading cuz the whole time we were looking for the big white connector, when in fact the connector itself is no bigger than 1/2 an inch wide.. other than that, everything works.

i have a may AVIC-Z2 and downloaded the mega upload file put it onto a disk then installed the burned disk into my AVIC-Z2 and in about 3min it said it had to reboot it rebooted and i was then able to DRIVE & AND USE NAV & WATCH DVD AT THE SAME TIME ! thank you " Hyperite " YOU ARE THE MAN ! thank you leo in apple valley ca

I have just had the Z2 installed with the by-pass and it works great. I checked the Z2 version and it is 2.00 and I understand there is a 2.14 version out. My question is do I really need this up date? if I do will I loose the by-pass? If not how do I go about getting the update and installing it? What exactly does the update do?

Thanks

There was a firmware update put out if you are having problems with the deck freezing. It does not change your bypass. Its on Pioneer's site if you want it

First let me apologize, I know this thread has been done to death. I've read it all the way through, but I still have a question. My Z2 should be here this week, and I'll be installing it.

So in order to bypass it, do I need to:

A. Just do the two wire?

B. Do the two wire and run the ISO provided in this thread?

C. Get the latest firmware from Pioneer, get the freezing fix, and do the two wire?

I'm just confused, because from what people have been saying, it seems that with the freezing fix, you don't need the ISO. Also, does it matter when my Z2 was manufactured?

Again, my apologies, I'm sure I just missed the answers I need in the thread, but I want to make sure I'm doing it right.

Thanks, would appreciate any help.
