Pioneer AVIC-Z1/2/3 and steering wheel controls

[Vark]

Long time haven't been to the forums, but here I am

Anyway, I got a used AVIC-Z3 unit and have a question for those who have/had them installed in H2.
What module you use for steering wheel controls? my H2 is 2007 and I currently have Eclipse AVN-5435 installed, which has "native" steering wheel integration from what I have read. I got the truck used and it was already installed, so i don't know what they installed there, but from what I have read, that particular model does not require any PAC-type adapters.
I don't use onstar, but may be installing Bluetooth so want to use that "speak" button on steering wheel as well.
thank you in advance

You can use SWI-PS or SWI-R . Either will work properly.

I used the SWI-PS, works like a champ! I have the Z130-BT

I'm leaning towards SWI-PS, what revisions do you guys have?
Does it support bluetooth and that nifty voice feature for the maps?
Can you use that Onstar button to activate it (on the left with a picture of man talking)?
anything I should pay attention (or additional parts needed) for install?
thank you for replies

I use the bluetooth with the iphone and it works well. It syncs mostof the time. I am not sure what revion I have on the steering wheel interface. Maybe 2 times I have had it not work, but once I stopped and restarted the truck it started working again in about a 1 year period. I would get a Z130 just because the interface for browsing music is so much better.
