Same here, tried everything, sometimes it's off, most times it's on.... Just gotta remember to turn the volume down before shutting off (neighbors not liking my choice of music at 3:45 am, lol)....
Ditto here also. I always hit the power button before shutting off the ignition. I hit the kill switch 1st then radio, then ignition. It's hit or miss. Maybe we should try powering off the radio 1st before shutting the bike off? I lose my SiriusXm presets sometimes too.
