GRT Avionics

I bought an xm wx module second hand and have installed it. I didn't get any docs with it as to what its ID is. Also the GRT User manual offers no help.* Any help on getting this up and running?
thanks,
Don

*Note to GRT tech pub writers. Take a look at the Garmin GTN 650/750 user manual. That's now the gold standard for user manuals.

The unit should have the ID on it, or in the setup menu for weather, you will see the ID when you get it hooked up.
Then its a matter of activating with XM, then telling the unit through the EFIS to go into activation mode.
