pioneer xm radio

I need the service manual for pioneer gex-fm903xm tuner

[trev111111]

I'm still looking for that service manual. The reason that I am looking for it is that I have two GEX FM903xm radios here - one seems to be modified to receive satellite radio free, the other one is not. The modified one has an IC that the number does not cross reference - Pioneer tech support says it does not exist on the mother board. I work in electronics and am trying to get a service manual which might give me an idea as to how that IC is working - so maybe I can figure out what it is

This site appears to have a way to get one if you make some kind of a donation.
