Radio presets control?

I don't use the radio a lot, nor the phone, nav, apps since I enjoy listening to the rhythmic squeak of the rear leaf pack...but how do I get rid of the 1-5 radio stations presets? Nothing I tried works. I want to make them my stations and get rid of the XM preset.

 

Tune to the station you like, then hold down the preset you want to assign it to for five seconds or so.

No worky. I tried.
- tune to 92.3FM
- hold preset 1 for a time. It changes to the preset station and never changes to the station before.

 

Probably because 92.3 is already on number 6?
Long click and save something else to number 6 them put 92.3 where you want.

 

Thats weird. I dunno, it always worked for me.

 

This has always worked for me.
