That's a bummer OldHiker.
The wait is worth it for the music though.
$60 sounds about right for the install. I could do another one in under 2 hours. There was a lot to figure out the first time. Plus those guys in the install shops have the quick connecters and stuff to speed it up.
The SIR-GM1 would be simple to install if the factory XM was there. No need to remove radio then, just open glove box and unplug the old XM and plug in the new Sirius unit. You reuse the same mount and the wire will reach. Putting the Sirius in where no XM was before requires much more work.
