XM Radio doesn't respond

I usually drive my 2022 Niro EV with map on large-left section of entertainment screen and XM Radio on the small-right section of screen. Works fine, usually. But just last week, strange thing started happening. I cannot change XM radio station - the right- and left- change-channel arrow/buttons (on small-right portion of XM screen) don't respond anymore. But all other buttons on screen (such as map and menu) work OK.

Even worse, if I press the "Radio" button in dash, which should switch XM radio to the large-left section of the screen, instead I see nothing on left side, while on the right side there's a flashing map (on and off every 5 seconds or so).

I've tried using a pen to reset the entertainment unit, and it restarts OK, but same problem.
Any other ideas before I contact my local Kia dealer?

 

I was ready to set up an appointment at my local Kia dealer to fix the problem I mentioned above.
But I read a Reddit posting saying there's a new software update available online, and although I just updated my infotainment/map system in early January, darn it if they weren't right. There was a new version dated Feb 3, 2023, which I decided to install.

While installing it, it told me the maps were the same as the version I currently had, but I went forward and installed it anyway, and the weird infotainment screen flashing and refusal to change XM radio stations were gone! The infotainment screen is working OK again.
