Just a note. If you have a June 06 and older Z1 and you do this fix my flasher will no longer work. It upgrades the Z1's to the July 06 and later bypass.
AGAIN.... If you install this CD, my flasher circuit will no longer bypass the Z1. You will need to use the 07/06 Bypass (2 wire ground) listed here:

If you choose to install this CD.
You install this update AT YOUR OWN RISK!
You can continue to read through this thread for my problem I had installing this CD if you wish. I had problems. And I don't want any of you surprised to find out your flasher bypass no longer works.
I would recommend that you try the non-update first:
http://avic411.com/forum/viewtopic.php?t=2450
Turn your cell phone speaker volume down to it's lowest setting (not the ringer volume, but the ear piece volume) before pairing your phone to the Z1. If it's already paired, you need to do a level 3 reset to get rid of your phone (see the manual for the level/mode 3 reset procedures and what you will keep and lose) before repairing it. This worked very well for me but not quite as well as the update.
Actually it is true, he told me that some kid came by and he did the upgrade for him, 20 minutes later he called back saying that his flasher bypass no longer worked.
What I also heard was that after this upgrade the 2 wire ground bypass DID work though.
I cant get the link to work it goes to some site that says I have to purchase the info what is the bluetooth problem is it the echo in the mic and what is the fix

You can get to it for free, but there is a waiting period and it's not really intuitive.
Ok, how about I'll waste some of my bandwidth:

Note, I'm just reposting what LeonPhelps posted. I have NOT tried this yet, I have extracted the files and poked around in the iso. But I have not stuck this into my Z1 to see if it does anything. I'm not "endorsing it" just posting it on a site with "easier" downloading.
I will eventually try this with mine, but I want to do it when I have time to do the new 2 wire ground bypass.
Seems like the end of SMinntech 
I will post something on my site once I test this.
Just tested on mine, it does improve a little but I found that it worked even better when I put the setting for volume out of the right speaker only. With the right speaker there was no echo at all.
Oops Sorry
I had this update a couple of months ago, I have not been here for a few months.
Anyway, the update helps some. I can turn the volume up more before I get feedback.
I am not sure about the bypass, My original Z1 had a ducatiboy flasher circuit. That units motorized face had a bad accident and was replaced with a new unit, we will not get into the accident 
. I have not done the new bypass on this unit yet.

BTW: hello and thanks for all the hard work ducatiboy

Would it be a problem, if I left the "flasher" connected and than did the new bypass? I am assuming the map update in 07 will "fix" the flasher bypass as well. So I might as well fix my BT now and switch the bypass now also.
FWIW, I just installed my unit today. The build date is Sept, I think. When I tried installing the fix it said it was already installed. I wish I could let everyone know if the fix remedies the echo but I can't get my HTC S620 (T-Mobile Dash) to work with the AVIC yet.

Nope it won't hurt anything. The only "negative" is that if the circuit ever did fail, the Z1 wouldn't dim when you turned the headlights on. But it would have done that anyway if it failed. But now, it won't hurt anything (as far as I know). I would hate to find out that if you tried flashing your lights, the Z1 would, on purpose, lock you out of stuff out of spite. But I doubt the pioneer engineers did something like that.
so this fix may just be a band aid for the problem as well since the update was said to already be installed on bfly's unit? Ill go try this right now and post back

I finally got my phone working with the Z1 (JETware Hands-free Extension was the problem). After pairing the phone I gave a friend of mine a call who is usually pretty critical about call quality. He said it sounded fine, no echo.
Set-up = Mic on the driver side a-pillar near the roof line and speaker only coming out of the driver side.
bfly, thats great, i was noting though that your unit did not take the update since it already had it, didnt it?
anyways, tried this update and...
1. Yes it does update... it goes through a double confirmation to ensure you want to update. It also mentions features will be disabled during the update, and then prompts to let you know that the features will be enabled after reboot.
2. YES it seems to improve the bluetooth piece, and its functionality. I placed a few calls to different people using different types of phones, such as cellular and land lines, and even voip. All of which yielded not one echo, not one complained until I raised the volume on the z1 phone volume to 80% or so, then they complained of echo. Keep in mind that is well over 3/4 the way up on the volume and is rather loud anyways.
3. Perhaps this fix has been available in newly manufactured units since bfly's unit woudnt take the update, and since its been said that this update has been out for a couple months already.
A bit more testing and testing from other people might help more, but it does look good thus far.
P.S. not sure if this is related but it seemed to improve the voice command part of the z1 also. For example, when dictating to the unit it seemed to respond more accurately.
Ok so I installed the flasher bypass awhile back cause my unit was one of the first out. But what I am hearing is that if I do the BT update that will no longer work right? At that point what will I be able to do to get it bypass again? Thanks for the great forum and help!

I think what some are reporting, but it's not totally confirmed yet, is that you'll be able to do the July 07 bypass....doing the connector 2 ground, etc.
but, that's totally not confirmed yet as to what that does. Meaning, does that do anything else, etc.
I think we are all waiting on some more testing.
I'm going to wait on Ducatiboy to confirm all this.

I do plan on doing this update to my personal March 06 unit. Verifying that this really stops the flasher from bypassing and also that the 2 wire ground will then bypass the unit. I just won't be able to get to this till Sunday at the earliest. I will do this and report on my findings, but I can't do it for a few days.
i downloaded the BT fix from Sminntech.com, unzipped and burned to cd, inserted the cd in my Z1 and it tells me a CD ROM has been inserted but that's as far as it goes. do i need to be in a particular place on the Z1 to activate or enable it, or enable some kind of autoplay? i'll keep messing with it but if someone can offer advice i'll be the guinea pig for this fix. thanks
such is the life of a guinea pig, i got the disk installed (need to be on map screen). i reregistered my phone and tried test phone calls on various volume and speaker settings. i was told the echo was still there but not as bad but i also had the spkr volume turned right down so with any outside noise it would probably be too quiet to hear anyways. to summarize it, i don't think the echo issue is fixed and now i've disabled the flasher. i tried methods 1,2, and 3 of rebooting the HD but i still cannot override the lockouts. Ducatiboy, we'll be looking for a new fix from you.

woodman171,
you could just try the connector 2 ground bypass and see if that works. Since your flasher doesn't work anymore, I would try that.
woodman, what exactally did you do to get the update to work? I have the same problem you did. All i get is cd rom inserted after putting in the cd. I've tried inserting it on both the av and map screens but get the same response.
Do you need to put the iso file in any type of folder? i just burned it all by itself on the cd. Do I need to include dummy data with it to equal at least 100mb?
I have the newer HU that is bypassed using the two ground wires since the flasher circuit did not work.
Any input on this problem would help.
Thanks

Ah, I knew this was going to happen when I saw that the file was an ISO. An ISO is not a file you put on the disk, the ISO file is instructions to tell a burning program to re-create the disk. See the difference?
CD roms (and dvd's for that matter) have all sorts of settings to configure and they also contain data. This ISO file has both, it's a snapshot of the CD, so another program on another computer can re-create an identical copy of the disk.
I don't know what program you use for burning, but you can't use windows cd writer. In Nero, I believe you click on Burner - Burn Image (or in 7 it's File - burn image). Look here for a more complete list.

or
Had a feeling something like that was going on...when I clicked on the iso file on my computer, a CD copy program opened and asked if I wanted to burn the CD....Just like it was supposed to.
Will give it another try and report back on the installation and the 2 wire bypass.
You are a life saver..Thanks again!!
Again, ducatiboy comes through with flying colors. I was able to burn the iso image into a usuable update cd and the unit updated just fine.
And the good news is the 2 wire bypass is unaffected--all funtions are still available while driving including DVD viewing!!
Now i just need someone to call to see if the echo has been fixed.
If anyone needs the update CD, just let me know and I will be happy to mail it out to you.
