I didn't think Sirius XM made a unit with bluetooth connectivity. That would be one option.
I would use a Sirius XM car unit. Plug the power into a cigarette lighter outlet (or hard wire like Bob did). Then plug the 1/8" audio plug into a music input jack on the audio panel. That assumes you have an audio panel with that capability.
The gdl51r also provides low latency weather .
This is anecdotal information .......There were few that said the ADSB miight be delayed 20 min, whereas the XM is near real time. YMMV
