Ghost channel change

I will be listening to a channel (rawdog for instance), and all of a sudden it will change to sirius stars 102. It doesn't matter what channel I'm on, it will always jump to 102. It won't do it for a month, then will jump 3-4 times an hour Strange or what

Okay, definitely do not spend $500, that is crazy, but I think I got your issue here. Since the Sirius / XM merger, there are sometimes 2 different stations, on Sirius, the other XM. With channel updates things have changed a bit. For instance, your channel 144 is probably now channel 123. Channel 36 can be found going to channel 81. So basically replace those two presets with the new channel numbers, 123 and 81.

Hope that helps!!

Good luck,

Go to your channel selector and move it to Channel 0. That should be where they are running their free promotion.

You need to call sirius @ 1-888-GET-SIRIUS (438-7474) and they will remotly reset the radio for you. This has happened to me twice and this is the only way i have found to fix it.

All of a sudden the display says invalid channel and 0% updating channels sirius says the radio must be broken

I would try a different antenna first, then exchange radio if that doesn't work. You will have to 'update' the radio for about 30 minutes after you first activate it, but after 30 minutes it should be fine. Try the activation channel (channel 1) - call Sirius for a 'refresh'. After 30 minutes, your undate should be done. Turn the radio off with the pushbutton on the radio. Turn it back on - should be no more updating. If so, then there is a problem.

Sirius Radio Invalid Channel message

1) Do you have a Sirius account?

2) Have you called Sirius and given the serial number of that receiver?

Those are the first two things you have to do to get a Sirius receiver working. (The original owner could have changed his account to use his new receiver, if he has one.) Go to - the "activate" part - for details.

&R=11812445&C=17577363&K=NBy0rr?h=2mv3s7&r=11812445 Your SIRIUS radio contains an FM transmitter that allows it to operate wirelessly through your car FM radio. We have determined that the output of this transmitter exceeds the limits established by the Federal Communications Commission (FCC). As a result, the unit may interfere with the performance of radios operating in areas adjacent to your radio. There are no health or safety concerns associated with this issue.
  • If you listen to your SIRIUS radio wirelessly through your vehicle's FM radio, then please review the solutions listed below and select the one that works best for you. SIRIUS will provide you the best solution at no cost.
  • If you use your SIRIUS radio only when docked in a boombox, or directly connected to your car radio or home stereo using audio cables or a cassette tape adapter, then no interference can occur and no further action is required, provided you have turned off your FM transmitter. To turn off the FM transmitter, first press the MENU button. Use the channel up/down buttons to highlight “FM Transmitter” and push the SELECT button. Use the channel up/down buttons to highlight the "FM On/Off" menu item and then press the SELECT button. Use the up/down buttons to highlight "FM Off" and press the SELECT button. To exit the "FM On/Off" menu, press the MENU button. Use the same procedure to turn off the FM transmitter if you use Solution 1 or Solution 2 below..
Solution 1 - Direct Wired Audio Connection: If your vehicle radio has a “LINE IN” or “AUX IN” jack, you can use a stereo cable to connect directly to your SIRIUS radio. This solution is the easiest to install and provides the best audio performance. Many newer vehicles provide the required audio input jack. It will normally be found on or near the front faceplate of your vehicle’s radio.


Solution 2 - Cassette Tape Adapter
: If your vehicle has a cassette tape player, you can use a cassette adapter that allows you to play your SIRIUS radio through the cassette portion of your vehicle radio. The adapter slips into your vehicle radio as easily as a cassette tape and provides better performance than a wireless connection. fcc_a_2.jpg

Solution 3 - FM Extender Cable Kit: An FM extender cable will provide a special transmitter antenna that allows you to obtain the best audio performance through your vehicle’s FM radio. This solution is easy to self-install, but does require that an easy-to-hide wire be run in your vehicle so the transmitter antenna can be placed in close proximity to your vehicle’s radio antenna. Using this FM Extender Cable Kit, you will continue to use your SIRIUS radio exactly the same way as you do currently. fcc_a_3.jpg

Solution 4 - FM Direct Adapter with Professional Installation: An FM Direct Adapter provides a wired connection between your SIRIUS radio and your vehicle’s radio. You will continue to listen to your SIRIUS radio through the FM tuner of your car radio, but the FM Direct Adapter eliminates the outside static and interference you sometimes experience when using a wireless FM connection. This solution usually requires professional installation. We will provide a certificate redeemable for installation at an installation center in your area.
Please go to and select the solution that works best for you. If you have any questions, please call 1-(877) 635-5130. Detailed instructions will be included with your solution.
You will improve the performance of your SIRIUS radio and reduce the potential for interfering with adjacent radios if you properly tune your FM transmitter. Please see the FM Transmitter Set-Up Tips below for more information.
We are sorry for this inconvenience. We are confident these solutions will allow you to continue to enjoy the great music, news, sports and entertainment that only SIRIUS Satellite Radio can offer with no impact on your radio’s performance.


FM Transmitter Set-Up Tips

To tune your FM transmitter turn off your SIRIUS radio and tune through the FM channels on your vehicle’s radio to locate an FM channel (except 87.7/87.9) that is not broadcasting in your area. If you use an FM channel that is being used by a local broadcaster, it will interfere with the performance of your SIRIUS radio. Once you have located an FM channel that is not being used for broadcasting in your area, save it as a preset on your vehicle radio. This will become your SIRIUS preset. If you’re not sure which FM channels are not being used in your home or travel cities, you can go to and search for an FM channel based on zip code.
Turn on your SIRIUS radio. In the SETTINGS or MENU on your SIRIUS radio, locate the “FM Frequency” adjustments. Set the channel number on your SIRIUS radio to match the SIRIUS preset on your vehicle radio. Refer to your user guide for detailed instructions on how to do this. The FM transmitter in your SIRIUS radio is automatically set to FM channel 88.1. This may not be the best channel in your area.

Display "Updating"

I am having the same issue with my Eclipse radio with Sirius. I called my installer - Al & Ed's - this was the first that they have heard of this. This suggested that the unit be powered down - disconnected and reconnect the power - but warned me that all of the presets would be lost.

I am going to take it in and have them do that. I will re-post re the outcome.

Very frustrating.
