I had a portable XM radio plugged in to the audio input, but between the
power, antenna, and audio cables it was messy and cumbersome.

I took a different musical route for my Skylane. At home I have the ability
to capture XM radio into 1-2 hour long .mp3 files. I download 20-30 hours
worth of music to my my RIO mp3 player and use the mp3 player in the plane.
The player is tiny and has a single wire from the player to the input jack
for my audio input. Very clean and easy setup.
