All of a sudden my radio displayed acquiring signal and now nothing will work. I have reset it to factory default and still nothing.

Resetting the Printer to Factory Default

Settings

Resetting the printer to factory default settings can be useful when

you are troubleshooting with the printer.

CAUTION Resetting factory defaults clears the page buffer, removes downloaded

fonts and macros, and returns all print menu settings to factory defaults.

To reset the printer to factory default settings

1 Press MENU until RESETS MENU displays.

2 Press ITEM until RESTORE FACTORY SETTINGS displays.

3 Press SELECT until the following message appears:

RESTORING

FACTORY SETTINGS

This message displays until the printer has completed the
initialization

Reset to Factory Defaults (Pg. 34)

Reset to Factory Defaults will set back all radio

features to the original factory default settings.

To do so, press PTT, SB2 and SB1

simultaneously while turning ON the radio until
you hear a high tone chirp.

Here is a link to the user guide: http://www.twowayradiosfor.com/pdf/RDX-Non-Display-manual.pdf
Programming instructions begin on page 36.

Best regards.

www.tssradio.com can help you fix it.

Remove back cover and leave battery in. There is a tiny hole that you can use a small paperclip to do a RESET. After that, plug your AC adapter directly into the bottom of the radio. Go to MENU and select "SET FACTORY DEFAULTS". Then turn off, wait a minute, turn back on again and select "mode" to see if you can hear your prerecorded music. If these don't work, then you likely do have a defective unit. Let me know how this works for you - okay?

I have a 3 year old Sportster 2 replay unit that worked perfect until 1 month ago. I posted my problem on this website a day before you did with this same problem. I googled to no end and even spoke to Sirius who wasn't willing to replace my unit at no charge since it was out of warranty. I found an unusual solution on the internet that worked for me. I place my receiver in the freezer for at least 20 minutes (this was recommended by a guy somewhere on the internet with the same problem). I have actually left it in freezer overnight too. This has solved my problem. It is the craziest thing but I thought I would try it before I resorted to replacing all my accessories and receiver since Sirius was less than cooperative with the issue. Anyway, hope this helps.

Try resetting it to defaults if you haven't done that yet. I had a similar problem with a Stratus 4, and that took care of it for me.. Sounds like perhaps some kind of NVRAM gets corrupted and a full reset clears it up.

Good Luck. Hope it helps you like it did me.. Just remember to jot down all your presets first, because you will need to reset them.

Hi guys!! I am a sirius satellite radio employee and unfortunately, when this happens (usually when the receiver is about 2 years old) the radio is pretty much shot. It is a common problem with the older sportster models, but not so much with the newer one. As the receivers are probably more than a year old, they are now out of warranty and the only resolution is to call us at sirius and say you want to cancel the subscription on the radio. When cancellation is imminent, we will offer to send you a replacement (although it will be a different unit not compatible with you current docking stations) at no cost to you. Sometimes an antenna replacement will actually stop the problem, but it will happen again very shortly afterward, and thus it is only a temp fix to a permanent problem. Hope this helps you out!!

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....

Sirius does not stand behind their products, There is no out of warranty repair for their radios,  and they do not offer sites for repair. Seems  like this is a definite problem with this model. Their solution is to buy a new radio,(with all the new-docking,boombox etc) accessories. also they charge $75.00 to change to the new radio.I liked my sportster 1 because of the FM modulator. It just had to be centrally located and all the radios in my home picked it up(no docking) the new radios require $50.00 docking stations for each stereo location and radio location, unless you bring a boombox everywhere, and the sound isn't the same.    I feel there should be a class action lawsuit against Sirius for these reasons and I might look into it. What do all you think?

my guess is that in some point u droped it or something like that the problem sounds like a crystal fault and with u cannot do nothing before u send it to fix try opening the device and see if the wireing of the antenna R fine good luck windman
