From what I was reading the the owners manual for the upgraded Pioneer head unit, it looks like XM is the only serivce that this particular head unit offers us to install.

I already have a Sirius radio tuner box from a previous vehicle that I owned and I wish to install it with this upgraded head unit.

Is this correct; we can only install XM and not Sirius?

Thanks.

Our xB2's are "Satellite Ready" meaning the head unit is capable of seeing ANY satellite tuner where a non-sat-ready head unit would not be able to see the tuner.

To answer your question better......I have a Sirius tuner in my xb2 and it works great.

Just making sure. I know what the Sirius output plug looks like for Pioneers and from the image in the manual, it doesn't look like there is a outlet for it.

I will check later.
