AVIC-Z1 INSTALLED!!

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.
