Sirius s50.... I installed my sirius studio on my new computer .... when i plug my s50 to the computer it dosn't show up on the playlist....i cant drag anything to my s50...

I had the exact same problem happen to me yesterday with my S50. My guess is that the software got corrupted somehow. I fixed mine last night be reinstalling S50 software via USB cable to my PC. Note: You need My Sirius Studio application loaded on your PC. Be sure to press Exit button on My Sirius Software Ap after you reinstall S/W. Patiently wait for S50 to 100% complete before disconnecting. Then, manually turn on S50 (while holding in your hand); do NOT put in car/home dock yet. S50 will then update S/W. When this completes, now you can put in dock. I don't exactly recall, but I think the S50 indicated the dock was being updated, then it defaulted to channel 184 indicating to call Sirius to subscribe. Since I already have a subscription in place on my S50, I just pressed channel 2 (The Blend) from my remote, and then my S50 began updating all channels. Success! I'm so happy my S50 is now working again! Good luck to others experiencing same problem; hope this helps! I can only imagine the frustration trying to get help from Sirius folks for this type of problem...

I am most certain that you have to return the radio most likely you do have a faulty radio and you have only one or two choices here. Return or take it to a tech...I would use the warrenty and send it back...sounds very faulty...this is common with these radios.

Firmware version was too old to be reconized by new version of My Sirius Studio (MSS). Put Stiletto into recovery mode, pulled the latest driver from sirius, updated, which allowed MSS to see the unit.

make sure your device is fully charged, then attempt to turn on again. you may need to use the restore tool available thru the sirius website or mysirius studio.

Remove battery for 10 seconds and re-try.

bring back to the store broken product

When the S50 is place overnight in the Home Base Unit or connected to the AC Adapter it will not charge battery completely.
The I have purchased two new batteries and both have not been properly charge by the units mentioned.
The charge provided to the Battery is of short duration 10 or 15 minutes maximum.
I have telephoned Sirius Company and their response was that they don’t have repair service for this unit any longer.

You have to use My Sirius Studio as the interface to your S50 to add/remove MP3 songs. Depending on your Windows version (hopefully 2000 or later) you should be able to connect via USB and Windows will autodetect the device. My Sirius Studio is a poor man's iTunes where you have to add music files before you can drag them to the playlists you created on your S50. You can download the software from the Sirius web site, including the latest update. Keep in mind you have to disconnect the S50 from My Sirius Studio. You can't copy files to it and then unplug the USB cable.

It's a bug.  I hit this as well.  You've gotta update the firmware, and you will stll have to delete all your songs and start from scratch before it will work normal again. 

The number for Sirius is (800)869-5364. They are very helpful when I had the same locking up problem. They will walk you through the process to update the item. Worked 100%^!
Had absolutely nothing to do with the battery.
