I was checking into the Z1 on pioneer's site and it seems to only mention that it's compatible with XM radio. However Crutchfield has the Sirius tuner listed as an addon for it.

Can you use Sirius with the Z1, and if so is the interface intuitive or a joke?

Thanks :)

Yes you can, the part # is SIRPNR2. I actually have both XM & Sirius on my Z1. the interface is pretty much the same as the XM.

The SIRPNR1 will also work (I have this installed in the Mustang)
