Well ain't that a whoot. I bought mine from radio shack a month ago and threw away the recipt and the packaging. I guess I'll just buy another unit (but not the sportster.)

Re: Sportster 4 not working...

My sportster 4 won't boot up past the splash screen either. Sirius said it's a memory problem and i need a new one. Of course, my warranty just ended 2 months ago. That's frustrating.

Re: Sportster 4 not working...

This sounds like a power problem with way the vehicle's lighter power works... If I have my car running and I turn the ignition off but just to acc (not ignition off to pull the key out), my sirius stays on but as soon as start my car again from the acc ignition position the sirius turn's off then reboots and crashs in the startup. Clearly my car cuts the power to the lighter while using the starter... and this sequence causes my sirius to crash. All i have to do is turn my car off to the point where i can pull out the key and start it from there... then my sirius boots up fine.

maybe there is a voltage problem with how the sirius auto starts when power is connected??

Re: Sportster 4 not working...

I had the same issue. This is what Sirius calls a "Frozen Unit". There is no bypass, unfortunately, and it must be returned.


I had mine for 3 days and it froze on the Sirius Logo screen when booting up. If you bought the unit from Sirius, you must contact their E-Commerce department. If bought from a retailer, take it back to the store.


Sorry, mate.

I own a Sirius Sportster 1, up until the other day it was working perfectly. It now is working as if it the service has been terminated. It does not complain of lack of signal or antenna. Everything...

They recently updated all of the channel line ups, and since then some of the older receivers have had some issues updating. I don't know that there is a fix for this, however, if you look on the back of the receiver, your SID/ESN number should be displayed there (in addition to on channel 0). If you have them resend a signal, hopefully this should correct the issue.

Sirius Receiver goes silent and displays Acquiring Signal.

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.

Sportster 4

Did u go to the menu to get the Sirius ID# or ESN# or did u get it from the box or back of the unit itself?? I used to work in activations department for sirius and the most common reason that a plug and play unit would not activate is a mismatch in ID #'s. I have seen units with one ID number, but the box or the back of the radio actually being labeled with a different number. By the way,only one signal can be sent to the radio every 20 minutes or so and most reps you talk to don't even know this. So after sending the first signal, all they are doing is clicking a button on the screen and getting a message back that says "Duplicate Provision" meaning that the signal cannot be sent because it is already sent. If you were hearing audio on channel 184 when the signal was sent and you made no adjustments during this time, and the SID or ESN number is the correct one for your unit, and the radio doesn't activate, I would get a replacement. But this never happens in my experience unless there are other signs of defect.

Hope this helps!!

Sportster randomly turns off.

Remove the batteries from the boombox. If there is no batteries in the boombox, and it still does this, then the boombox itself is no longer any good.

Power but no signal

I work for sirius so I know about all of these different issues and the most common one is the connections. It is imperative that the radios be connected to power with the cig lighter adapter. This adapter had circuitry in it that lowers the cars 12 volts to 5 volts which the sirius unit ooerates on. The old units were 12 volt and could hard wired into the vehicles fuse block, but all of the new radios operate on 5 volts. If this is not the issue with either of you then you have defective units. Being that all warranty replacement are with remanufactured units, your chance of getting a problematic unit increases after the initial return of your new unit.

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....

Sirius sportster sp-tk1, always displays "acquiring signal"

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?

Sirius XTR1 Receiver cycles on dog screen with beep - keyboard locked

Hello, I had the same problem with my xact xtr1 and I was advised by xact that they have no repair process in works and most likely wont. They did say let it run for 10 minutes and once you have a menu switch to factory defaults which proves to be a worthless fix. I would have to pay $39.95 for a new radio...horrible customer service. The bright side is that Sirius will not charge me the $75.00 transfer fee as a good faith gesture. I have decided to switch to another radio and leave the Xact brand out of the equation, if there is no upgrade or modification to the existing equipment why set yourself up for a future failure.

Power but no signal

I am running into the same exact issue. I have had my Sportster about 14 months now and this is the first problem I've encountered. We had a cold night in the low 20s and the next morning the Sportster started in with these issues. It's been two weeks now and I have the same exact issues (have power, all connections in tact, no "no signal" message, etc.). Sirius recommended a factory reset through the menu option. I was able to do that, but the problem was not corrected. If anyone has any advice here, please let us know..... Thank you. -Peter

Sirius not working after taking to dealership for unrelated problem

How did the dealership resolve the battery draw issue. Did they rewire the Sirius for you. If so they could have wired the unit wrong. If you have a newer vehicle most of the wires in the dash are a very light gauge and most fuctions are controlled by, what's called a Body Control Module. Some of these wires are not a very good place to draw power from not onlt could it damage your Sirius Radio it could damage the electronics in your car as well. I suggest getting it looked at by a professional. Then go from there.
