Re: only on/off chimes come through radio

The input source is controlled by contacts in the actual input on the side of the radio. It sounds like the contact for an aux connection is stuck closed. The contacts need to be separated, and probably the only way to do this is to disassemble the radio. If it is under warranty (less than a year old), I would suggest calling SIRIUS warranty for a replacement. If not, and you don't feel comfortable taking the unit apart, find someone who is because the unit is most likely salvageable!

My old unit stopped working;(worked perfect for many years) so I replaced with a new same model and I have bad interference and FM static. Sometimes the FM station overrides the express radio and all you...

The very first XM radios, (SkyFi2, MyFi, Roady2) up until they were put in red boxes, had a VERY strong FM transmitter, so strong, that when Sirius was their enemy, they complained to the FCC and they made the FM transmitters real weaklings. So unless you have one of the first two batches of XM radios, the FM transmitters now are real junk and you're better off using an AUX input on the radio or a cassette tape adapter. Okay? Thanks.

The low signal may be due to loose connection of the antenna cable

The static level is so high I am unable to hear the radio.

Under menu, select FM frequency. Try using different frequency. A nearby FM station could be bleeding its signal onto the FM frequency your unit is using by default.

My receiver comes on and I get the error message "Acquiring Signal" and everything appears to be connected. Just started doing this. Using the Aux. jack in my Nissan. still need a sirius antenna plugged into the device. If you just started using this you may just need to resend the signal. Just call the sirius/xm people and follow the recorded prompts to send a new satellite signal. Then make sure you are parked somewhere that it is receiving a good signal and wait. It could take up to 30 minutes to reset completely.

Loud High pitched noise

That's interference from some microwave transmitter on a tower. The interfering signal is covered up by a strong satellite signal. When you lose the strong satellite signal, then the ground-based microwave signal takes over, which your receiver trys to play back. (It's an unintelligible encrypted signal)

Is there a tower with a big "drum" pointing in your antenna's general direction? Are there "stunned" (or dead) birds in your parking lot from time-to-time? Your antenna must be moved to a different part of the roof, or even relocate it to the side of the building where you have direct line-of-signal to the satellite.

Hope this helps!

Sirius Stiletto 2 constantly "acquiring signal"

This is an odd fix, but I read it yesterday after having the "Acquiring Signal" issue for a week. I put it in the freezer for 30 minutes, brought it back to my desk and now it works. I don't know why or how, but I am happy.

FM output

I had the same problem. Only thing that I came up with that was consistant is plugging it into the aux jack on my radio so you don't have to depend on FM frequency. But, my unit crapped out this week and I hope it is under warranty.

Sirius radio with xm antenna

Not advised. They have different resistance and are set up for different Sat signals. Chances are you will decrease the life of your radio if you get a signal at all.

SIRIUS Sportster "Acquiring Signal"

Let me save you $30.00. A new antenna will not help, nor will cleaning the contacts. I just did both of those and it did not help. I have mine in the freezer right now cooling it down. Sirius told me that I should not leave it in the car because it gets to hot. They told me to buy another unit....

No Signal After Reconnecting Roady2

Try playing the Roady 2 through a fm radio with the audio jack(middle connection) disconnected and the FM Frequency & Fm Radio set to the same station. At least this will tell if the receiver is working. I suspect that you got an aftermarket audiojack for your stereo. Might want to check that. Go back to the manual FM Modulation setup instructions. Any FM receiver will work. Good Luck
