I'll try to explain...
On my 2018 Durango with the older Uconnect system, when I was on FM radio, it has its own presets you can set for favorites for FM channels. And when you went on SiriusXM it has its own presets for favorites. That way, when you are listening to FM radio, you can cycle through your favorite FM channels you saved, and when i clicked siriusXM, i could cycle though siriusXM saved favorites. Now with my 2021 Durango Hellcat, when i set 5 of my favorite FM channels, and then i click on siriusXM, the favorites still show my FM saved channels.. Is it just me or did i just forget how it worked?? shouldn't the favorites stay with the selected source??
