I am experiencing the same radio characteristics. First just 1 preset starting jumping from 106.5 to 98.5. Even if a tune the radio to 106.5 manually, it jumps. Now 2 stations are doing this.

I'm also experiecing the other related problem mentioned on at least 1 preset... after pressing the button the station changes but the display continues showing the previous station.

In my area (san francisco bay) I notice that I'm getting more PTY data then I used to... Not sure if some stations just starting transmitting PTY and if maybe this ridiculous radio (I'm not a fan) is not handling that correctly.
