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
