Sirius Sportster 4 Problem

My Sportster 4 has given me several problems since new. Backlight started going out slowly now it never comes on unless I squeeze the receiver top and bottom. Then I was having a problem with it not recognizing the antenna. That was resolved by pushing it down into the cradle. Now I'm getting an "acquiring signal" error. This one I have not yet resolved. Any suggestions?

    My sportster 4 will not work unless I squeeze it while in its cradle. When I let go I get the "antennae not detected" message. Works fine in the house but not the car.

Sell it or so many of the units run into this problem and nobody knows how to fix it.

Same problems here also, had sp-1 for 4 yrs no probs at all! I even have a brand new antenna, needed to be replaced any way, thought that would fix problem (ACQUIRING SIGNAL) No luck ,why does everything...

Go to XM, I did. But first, call Sirius and ask them to 'refresh' your receiver. Leave unit on channel 1 for 30 minutes and see if problem go away. Make sure to turn off and on with pushbutton on unit - not remote, and do not just diesconnect power..

My sirius radio sportster works sometimes and others doesn't

Buy radio shack electronic contact cleaner (in a can) and spray a small amount on the male connector from the antenna wire, and spray a small amount on the male connector in the base of the Sportster that the sportster interfaces with. Place the antenna connector onto the base unit and remove it several times and swirl it while connected. Place the sportster into and remove it from the base several times. This usually will fix the issue. Sat signals are extremely sensitive to the slightest oxidation or dirt or whaterver on that tiny antenna connection point.

Sportster 4

Dick,
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.

Sirius radio

Cliff, If you mean a schematic then u are going to have a tough time finding that. It is manufactured by Directed Electronics, so you might try to contact them, but they might not be willing to divulge that info.

Good luck!

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....

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.

Sirius Sportster

Unfortunately this is a fairly common problem in the Sportster, caused by worn contacts in the tuner. Sometimes you can temporarily resolve the problem by wedging a thin piece of cardboard behind the tuner in the cradle, to create a better contact; but eventually it will just wear out again.

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
