Give it time. It will need to process the data. Test with a brief recording. If it takes more than ten times the length of the recording, try reinstalling the software.

MODE picks whether you receive XM or listen to your recorded music. Press MODE so you can read a specific XM channel. Then (if you have an antenna & power) you can run the dial up & down

Leave the battery out and see. Do you have the sleep timer set, or have it set for recordings? Try a complete reset and see if that clears things up (unless you have recorded content you don't want to lose).

Press "mode" button so that the reciever is receiving music from satellite signal on the station you want to record. Then press "2Go" button - screen will ask you to press again to confirm - press again, and it will record whatever was being received. It will record over what was already in 2Go. In menu, under "myXm" there are choices to clear the entire memory of recorded music.

Don't use the wearable antenna - reputed to not work well - was not a good design idea - I don't think any of the other receivers have this feature if that tells you anything. Record music you like on the myXM feature, and play that when you would otherwise want to receive on the antenna. If you are listening to live news, etc, there may be no good solution. (I have read there is an antenna headset, but don't know much about it, but some reports that it works.)

I get the same problem once in a while. Try removing the back cover and hitting the reset button via a paper clip--then try accessing the stored content. The MyFi should "release" the stored content.
