A word of advice/caution:
Using the Pioneer crimp connectors may be convenient to ground the parking brake to the factory ground.
Mine is intermittently loose. Just solder it up like the rest of the connections so you do not have to redo it later.
I grounded:
1. The Unit (black wire)
2. The Parking Brake wire
3. The relocated Mute wire
All to the vehicle chassis (ground).
Works perfect.
I just installed my radio last night and only grounded the radio's black and parking brake light (light green) and did not work. I'll try adding the mute (yellow/black) cable to the ground as well 
Thanks for the tip!
does anyone tried software bypass on firmware 2.0? this is preventing me to upgrade as i do not have hardware bypass,only software bypass. does it works?

Dano,
I'm assuming you grounded the mute button after you switched the cable from its original location to the one shown in this post? or did you just grounded all 3 cables from their original locations?
Just wanted to confirm (for those who havent done a bypass yet) that I just edited the pioneer.ini using windows CE (SD bootable) from http://www.avic411.com/forum/viewtopic.php?t=17542 . You need a copy for the DATA.ZIP file located "My Flash Disk\APL2\iGo\ or inside LPUE080\APL2\iGo\ from the Pioneer update zip file (firmware 2.0 in my case). Open the "DATA.ZIP" file using WinRar (google if you dont have it), open the project_config foler and you'll find the pioneer.ini file.
Open the INI file and look for the line "parking_break_speed=16.0" and change the 16 to 200
Save the *.ini file and when prompted to update the archive (by winrar) select yes....
Now copy the new copy of the DATA.ZIP file into your SD card.
Download http://www.avic411.com/forum/download.php?id=4696 extract it and copy both folders in there into your SD card as well.
Now place the SD card in your F series (while is off), turn it on and it'll boot into windows CE. Once the copying process its done click on the "X" at the top right hand corner. Then click on START/PROGRAMS/WINDOWS EXPLORER and go to My Flash Disk\APL2\iGo\ rename the existing DATA.zip to DATA-OLD.zip and then copy the DATA.zip from your SD card into My Flash Disk\APL2\iGo\.
Works great (at least in my F900BT that is)
Hope this was detailed enough for everyone to understand.
willjv did you try it on firmware 2.0?
Yes Akka!
I am on FW 2.0 with an edited pioneer.ini (which was edited "after" i upgraded to 2.0)
Hey guys sorry for the bothersomness again. But im 100% new to all this stuff. I took the F90bt to audio express today to get a quote on install. They want 95 for install and another 40 for bypass. They say that you need a special module box to bypass the f90bt. after reading this forum i thought that was bs? is it? I see that you say theres a software hack. Well how do u get into the config files for the gps? on your computer? i mean how do u get the config files from the nav system onto the computer for editing? Also i understand the wiring procedure bypass method, but what do you mean by grounding the parking brake wire? like if i wanted to move the mute wire to the new slot before i take it to them for install how do i ground the other wire?THANKS!!!
I am a newbie and inexperience so I don't want to mess with the test mode (at least not now).
Will it work if I update the .ini file from LPUE080\APL2\iGo\ from the Pioneer update zip file (firmware 2.0) and then apply the upgrade?
Ive been browsing 411 for the past 3 days and i finally got it so i can watch movie while driving, thanks for all the info guys...
I have a 07 H2 and my 900 was installed by Best Buy. They did a good job and everything worked, but no help on the bypass. (can't blame them, not being a private shop and all) So I found this site and you guys are great! Thanks so much for what your doing, you have just elevated my purchase.
So needless to say, I did the bypass by myself which was a bit of a pain on the H2. The whole booting to windows CE and changing the GPS parking brake settings seemed a bit daunting for a newbee like me, but it wasn't all that bad. I had some trouble trying to edit the speed in the Winrar, so I had to open it in a word pad, then edit it and then copy that back into the winrar. weird...
I then needed to do the parking brake. I didn't know which wire was the parking brake, so I finally found someone's thread that said the light green wire coming out of the back of the deck, (black plug). Well I spliced onto that wire and ran it to a ground. Walah...it worked...minus the 2 hours of pulling my console apart to get to the wire in the H2. Crutchfield had the full step by step instructions for 10 bucks on taking it all apart, but I found a post that listed written instruction on how to pull it apart.
Thanks again guys!
followed the instructions and it worked great with my f-700. Thanks
I have the F900 BT. I tapped into the ground wire to the PB and it works but the brake light warning is now on. I guess i did this wrong. HELP?
ARRGGHHH!!!
I had a loose connection and was getting intermittent Parking Brake warnings. So I soldered instead of using the wire taps.
After a few days of no issues the warning signal came back on. I'm assuming I must not have the yel/brn fully seated as the wires are grounded at the same post with the main ground for the harness.
Unless you need to do a hard reset or something.
Time to uninstall the harness and start voltmeter testing on the bench before the reinstall. I am "teh suck".
Ok so if I understand
Take the parking brake wire from HU and ground it, then move the mute (yellow/black) wire from pin 1 to 2 (like on the pix). After do software bypass.
Is that all?
Well I removed the wire from the parking brake and just grounded it to the body. Warning light is off so I guess I am good to go. Next is the hard wire fix and I should have video.

If this software/hardware bypass will remove msg about improper connection of parking break wire?
Is this actually a picture guide? I can't see any photos on this thread. I am logged in and have no problem seeing photos in other threads.
I grounded my parking break and did the software bypass, but on two occasions(both noticed when I was going 80 on the highway)... I am getting an error that says something like:
Improper parking break lead detected. Please consult the manual...
Has anyone else got this? Why dose this come up? Does this have something to do with speed?
Software bypass (with parking lead grounded, mute not moved) is speed-dependent. All you do is control at what speed the system startes thinking you are driving with the parking brake engaged.
Just change the value in pioneer.ini to something higher...
So 128 reflects 80Mph?
That's what I was thinking...
But it's just a warning, all I have to do is press OK? Is that what it would have done above 10 MPH normally?
Yes. The value is in KM/h so 128/1.6=80M/h. It will lock out controls just as it would at 10 M/h with no bypass.
I use 256.0 -- I figure 160 M/h is fast enough not to be playing with the headunit
Ahhh I see . I shall do the same, thanks.
ive done a serious amount of reading on this forum, and i have read contradicting posts about this topic...i have already done the software bypass, do i only need to ground the parking brake wire?? do i also need to do the work with the mute wire??

Need to do both.
If you have the unit out, it is 2 minutes to slide the yel/blk out of pin 1 in the white harness and move it to the bottom row and 4 over. Too easy not to do. Especially if you ground the parking brake wire to the harness ground.
