Any luck? Not sure how often yours deleted, mine seems to be odd times.I got the update for the rear camera done. Z47. The tech told me it was also a radio update. The popping in the speakers when I open the doors is gone but I’ll have to wait and see on the presets. Hope something else doesn’t pop up.
If I drive it daily, it keeps them for a few days, then will randomly reset the AM/FM defaults, but keeps the SXM presets. If it sits for a few days, they'll all be deleted.
I noticed that when it deletes the presets, the radio lags and takes a long time to turn on. It will also reset my theme on the dash.
Odd thing today, the scroll knob didn't work, unless I was in a different menu off the radio display.
Buggiest system I've ever seen.
