I have Three Roady XT's that A/C adpaters have failed. All have a high-pitched noise and warm to the touch. One adapter has failed causing the radio to power-up and shut down. Are there other Delphi customer experiencing this problem? The only fix is another adapter and a aftermarket/universal adapter may be hard to find.
AC wall adapter was failing for me. Car adapter worked OK. Found a 2A 5V adapter and changed the connector with success. Again hearing occasional beep but in car, no explanation found. Have had several good years of service; should not complain.
I found the problem lies in the XM adapter after replacing with a new one. I went to Radio Shack, purchased an Enercell AC to DC power adapter with the switch on 5V and an "N" 273-188 Adaptaplug. Voila! No irritating buzzing noise. Not cheap, but did the trick!
I just got my radio and home kit today, the hi pitched noise is awful so I looked online and found you. I finally hooked the car adapter into a wall plug adapter and volla- NO NOISE! Whew.
It's a $9 adapter I got for my ipod car adapter....just has a hole to plug in the car adapter and you plug it into the wall.
I am also on my third adaptor and I have yet to listen to the Roady for more than 2 hours total over 6 months. I have tried to find an after market adaptor without success. I can find only a 2500 mA adapter and that won't power it up. Any suggestions?

I had exactly the same problem with my Roady XT. The power supply gradually failed, with the symptom that the reception kept getting weaker and more spotty. Finally, the Roady would not turn on. The screen flashed as you describe. I happened to have another 5VDC, 2A power supply in the closet from some other electronic gismo from the past (I save the power supplies just in case). the connector on the old power supply was not correct for the Roady XT, but a little surgery put the new plug on the old supply... (verified by a volt meter). When I plugged it in the Roady quickly turned on and showed full signal strength. This had never happened in 2 years of use. Apparently this radio needs more power than the stock power supply can provide. Now it "loads" stations in 2-3 seconds and never fades.
We've been having the same problem with our Roady XT unit at the office. Sometimes I think it's possessed because it goes in and out, changes to the mute mode, and sometimes turns itself off. Just got another Roady XT unit today. It played fine, then went into the mute mode. Called XM and they told me to reset unit to factory default. It's fine at the moment.
Basically, you just need to have the antenna unplugged when you power up, and push menu right away, then select. Not sure why, but it worked on all of my Roady XTs. On the oldest one I had to push menu more than once. Good luck!
