Disappearing Favorites


2020 AWD GT, 2008 FWD GT
I purchased my 2020 CX-9 in June. Since then, I have had my pre-programmed Favorite FM Radio and XM Radio channels get deleted twice in the last two months. My battery didn't die so I'm not sure what would have caused it. It's quite annoying to reprogram all my channels every few weeks. Has anyone else experienced this?

BTW, I'm still on the original firmware and have not upgraded to the latest.

I have a 2019 Signature and this has happened to me too. I think that it mostly happens when the infotainment crashes and reboots. At least, that has been my observation and it is irritating as hell.
Happened to me three times and and once initial SiriusXM trial ended .....no more loss of favorites. Have had issues with the sound on the infotainment lock and only work with CarPlay and not SiriusXM since then.
