I'm moving the conversation over here from the SBS... I figure if someone wants an answer they might as well come here where there are more people who will read them and respond... This question was from the Sirius S50 forum in the discussions of the firmware upgrade. Anyone Sending S50 to Sirius for Firmware Upgrade - Page 3 - SIRIUS Backstage Forum Normally when you upgrade the firmware you don't lose songs or content. The fact is that the S50 latest firmware did not upgrade on a lot of units and Sirius had/has a mail in program where you send in your radio and instead of upgrading you received a reconditioned unit and you lost all your old content. What you do lose sometimes is functionality... Many of the S50 upgrades took some functionality away from the radio such as FM modulator power and range of stations that you could use on your FM radio. They also took away the ability to save what was already in the record buffer if you wanted to save some content. But if all goes well and you can do an firmware upgrade with your S50, you won't lose your content.
