Are there any audio panels with *built-in* XM radio receivers on the market?

No, but there's one with Sirius (the PS Engineering PS8000).

I've owned a PS Engineering audio panel/intercom for two years now,
and you will be pray it from cold dead fingers. The squelch (DSP
based) is pure witchcraft, and the support from the company is
excellent. Mark, the founder, pops on these here groups from time to
time.

You can't go wrong with PS Engineering stuff.

Not a paid endorser, just a happy camper.
