Adding XM radio to factory Nissan radio

Trying to add an XM radio to a factory 95 NISSAN Pathfinder RADIO (model#PN-9661H) via the 8 PIN ROUND DIN (CD player connector).

Does any one know the pin out for this connector?

The only other way to add the XM is through an RF modulator and use 2 RF adapters for the special diversity plug.

I haven't found any adapter for that factory plug to use for XM. I think you'll have to go with the modulator.
