Clearing XM Radio Stations

Is there a way of removing radio stations once you have saved it? I have accidentally selected a couple of duplicates, and would like to remove them.

 

I can think of two options. Either put another station in its place or disconnect the battery which will reset all of them.

 

It's been a while since I had my battery disconnected, but I'm pretty sure the radio has non-volatile memory for the presets. I think it held on to my presets after my audio system upgrade. You can change the number of presets displayed from 6 to 36 in increments of 6 (through the Setup\Audio menu) or you can overwrite with another channel.

 

I have the same question. Another option, I think I haven't tried it yet, is to go into the radio setup screen. From there I think you can clear all of your presets. Again, a work around to something that should be an obvious feature, IMO.
