AVIC-Z1 INSTALLED!!

[BuzzH3]

Well, thanks to a lot of people on this forum I got the Pioneer AVIC-Z1 installed this past weekend. Here is some information about my install.

What I started with:
6-disc Monsoon system with factory XM Radio

What I installed:
AVIC-Z1
GEX-P10XMT (XM Radio & NavTraffic module)
CD-iB100ii (iPod module)
CD-SR1 (steering wheel remote control)
ND-BC1 (Rear view camera)

Parts needed:
Peripheral GMAH24B (OnStar module)
Peripheral GMAHCM (Chime module)
Scosche GM1595B (Dash Kit)

I got lucky and the VSS (speed sensor) lead was in the small stereo harness, so I tapped into it there. I noticed several people stated that they got their speed sensor working, but the slope was not working. When I turned the stereo on for the first time, I noticed that my slope was also not working. I found out that you need to drive around for a while for the stereo to initialize. Once it got enough data, the slope started working.
I was also able to tap into the reverse lead in the driver's side A-pillar.
I'm not sure if anyone else has had this problem, but I noticed that the trim ring that came with the Scosche kit does not fit without modification. I had to use the Dremel and take a little of the top inside edge in order for the face to open and close correctly. While this was not really a big deal, it is very difficult to get the edge perfectly straight when trimming it. Yes, I know, I'm a bit of a perfectionist. Also, the top edge of the ring doesn't line up to the dash opening just right. I am still trying to modify it a little to see if I can get it to line up better.
I think that I am going to buy the circuit board that someone on the AVIC411 forum created that enables all Nav functions that are normally disabled when the vehicle is moving. That forum is great for any information about the AVIC line. There are already people that have figured out how to replace the hard drive with a larger one. The Hacks section is very interesting.
A huge thanks to everyone on this forum that helped me with the install. It actually went very smoothly. I couldn't have done without all of the information I got here.

I will try to post some pictures tonight or tomorrow.

Congrats on the install, Can't wait to see pics of it. Do you have any pics of the install steps? I would be curious to find out what leads you tapped into for the reverse in the a-pillar as well as the vss in the wiring harness. Also, does anyone know if the parking brake bypass still works if you have the vss hooked up? Talking about the bypass where you just ground the lead.

I don't have pics of the install process, but I plan to open up the dash soon to add a few more things, so I will get some pics then.
In the A-pillar there are 2 groups of wires. If you look at the top of the a pillar, you can tell that one goes down the side of the vehicle and the other goes to the rear view mirror. The reverse lead is the brown wire in the group of wires leading to the rear view mirror.
The VSS lead is in cavity E of the small plug in the back of the stereo. It is a dark green/white wire. Be careful though because there are 2 wires of the same color. You want the one in cavity E. I don't know if all the H3's have the wire there though.
If you just ground the pk brake lead and have the vss lead hooked up, you will still loose access to some functions when you are moving. As soon as you stop at a light, they become active again. There is a circuit board that bascially connects between the illumination lead from the vehicle and the one going to the stereo. If you use this board, you can connect the VSS lead and leave the pk brake lead unconnected. You will have access to all functions all of the time.

Thanks for the info. Just as I expect with the vss hooked up so since I am not having an accuracy issues I think I will just leave it unplugged. I started out with the same system so mine should have that wire as well if I change my mind. Make sure to post here if you get that board to bypass the parking brake. Have not been on AVIC411 in a while and don't recall seeing it. I did recall there are two bundles of wires in the a-pillar from when I hard wired my radar detector so will probably tape in there.

Hey buzz got mine installed as well this weekend. Brilliant unit.

Have the same prob with the scosche and I will modify it this coming weekend as well. Let me know how your mod turned out.

thx

The trimming worked fine and it fits now, but I'm still trying to get the top edge of the trim ring to line up better with the dash opening. I will let you know.

The new chime module is a little strange. Every once in a while when I get in the H3 (keys no where near the ignition) the chime module will ding once.

[BuzzH3]

I have 1 more strange issue. Not sure if anyone has seen this issue with the Z1 too, but occasionally if I get into the vehicle and start it up quickly, the unit won't boot up. Even pressing the buttons does nothing. As soon as I turn the key back 1 notch, so the engine turns off and it is on acc power, the unit powers up. When starting the H3, if I turn it to acc first, pause for about 1 second then start it, everything powers up fine. I have checked and rechecked all of my wiring. It has done it 3 times so far.

[HummerNewbie]

I have no idea if I started it quickly or not but my D1 didn't boot one time. I shut the H3 off and restarted it and everything was good. Only happened that one time in the month and a half or so it has been installed.

[Mark805]

had the D-1 not boot up like HummerNewbie described... always fine if i restarted.

Lets see some of those custom backgrounds now!

[BuzzH3]

When I installed this system, I removed the AUX input and the HK Drive + Play iPod adapter. I am going to be selling these 2. If anyone is interested let me know or else I will just put them on eBay.

Why didnt you just use the factory XM antenna? It worked in mine.

I tried to, but the little notches on the inside of the connector did not match up with the ones on the GEX-P10XMT. It was easier to just run the new XM antenna then to hack around on the connector.

[Mark805]

ahhh.. yea.. you pull that connector cover off and it slips right in there.. i got the same setup

Grats on the installl... I've been very happy with the unit. And god bless the bypass.. saved my sanity playing a DVD for the g/f on a long road trip. (kept her busy... I of course never looked)

Hey guys.

My 3d hybrid mode does not work, and the sensor shows no speed pulse, however on the vehicle dynamics of the z1 it does record my vehicle speed.

First off what does 3d hybrid do anyway?

And my installer assured me the vss was hooked up.
I am kind of doubting that at this point, since these features should work.

Where is the vss wire located and what color is it?
Thank, in advance, for your help.
