Hello
You may have connected your XM with amp by aux input connection of the amp. Just unplug the connection and switch ON your amp only. If you hear this Buzz sound even the XM disconnected, surely your amplifiers' output section has damaged. Advance the volume of the amp, in this condition, and if the Buzz sound increase with volume, the amplifiers' tonal stage has got damaged. If you feel the amp is silent and the fault occurs when XM is connected, XM's audio output has damaged. If you gets only Buzz sound from XM, retune your XM and check whether it helps you. If it does not help, check your XM subscription details. If it is ok, and still XM didn't accept, the XM recevers' tuner section has got damaged, and it is irreparable. OK.

MANUAL FOR XM SKYBOX


Unit is very straightforward to operate. Hold down O/1 button for power. Use the "mode" pusbutton to cycle thru AM/FM/CD/AUX/XM. Treble & Bass settings are made by turning the 'tuning' knob.
For radio and satellite presets, hold in the numbered pushbutton until it beeps, and then it's set. You should be able to hear previews on XM channel 1,and that will help you with antenna setup. I highly suggest using the remote XM antenna. The built-in XM antenna need to be put 'propped-up' outslde, otherwise you have to use the external antenna. Use AC power as it eats batteries, or use rechargeable D batteries. Let me know if you have any more quesions. okay?

My xm plays extremely loud thru my car stereo.no matter what i set the volume at.it is either off when volume is set to zero or loud at any other setting.changing the output level on the xm receiver does...


Are you playing it directly thru your FM antenna connection, or using the RCA jacks? You have to set the FM modulator level. It is also possible that you have a new FM radio with a type of ALC that will raise the lever regardless, but your regular car radio volume control should work. do not wire this directly to a power amp, as you won't have the control that you need. Good luck, let me know more.

I have XM radio in my chevy malibu. Worked fine


I believe when the antenna loses power it does not show it on the screen sounds like there might be a break in the antenna wire or simply came out of socket in the rear of the radio.

XM Loading Problem for Volkswagen


I had the same issue. I called XM multiple time to have the signal resent. I told them I was receiving the preview channels and nothing else. I asked them multiple times if it could be hardware issue and they said no. I took it to the dealer and they ran a test ($98) and determined that the unit had failed. They didn't charge me for the $800 unit, but they did charge me $300 for the installation. Its working fine now.
