Avic Z3 Install ?'s

[DJKO]

I'm putting together a parts lists for everything I'll need to complete the install of an Avic Z3. I haven't seen anyone on here post info on it but I assume it would be very similar to the Z2.
Could someone who has installed the Z2 let me know the Man. and Model of the wiring harness and mount that worked for them. I have seen some posts stating that some of the double din kits hadn't worked out.
Also wondering that since I'm going from the 6 disc/cass. head unit to an aftermarket nav. unit, how it will get some of the necessary input data (i.e. speed sensoring), to properly function.
Anyway, all info you guys could give would be greatly appreciated. Here's what I got so far:

Wiring Harness?
Mounting Bracket?
OEM Nav. Bezel
Antenna Adapter
Avic Z3
Pioneer Ipod interface
Pioneer Sirius interface

Missing?....I have no steering wheel controls to worry about
