No Signal on my XM Radio

I just finished installing an Audiovox XM Radio in my car. I followed the instructions and called the XM hotline to have the radio activated. I waited an hour and went to my car still no signal, I called again and they were to re fresh the connection- 2 hours later no Signal. They told me to move the car away from trees and tall buildings which I did. Still I can not get a signal. Everything appears to be hooked up correctly. Please send any ideas.

    The problem was with the antenna, I had a defective one. I tried a second antenna and it all began working, all I had to do was call XM and have them refresh the signal.

    Thanks a bunch!!!

    I have the same radio for about a year (sept 06) I use it on my semi I am a regional driver going throughout the midwest. At first I had no problems when I use to run from from Chicago to Detriot everyday. Then about May 07 my signal started getting a little worst (no signal). I now drive with another company so I travel all around the midwest have tried another radios of the same model XCS9 and 3 different antennas (car, home and truck) still same problem I used it with and without RF adapter. As long as a strong signal is coming in it works but no go with a weak one and 99% of the time signal is weak. And thats the way it should work no signal no sound but where are all of the no signals coming from?? I used a different truck everyday but same model!!! So I only use unit at home which means I never hardly use it because I am on the road most of the time. All connections are right just as before. For instant if I go to North Lima, OH from Chicago and I take the I80/90 toll road there is no signal all the down and all the way back same problem going to Omaha, NE on I80. And the places I do get a signal its just for a little while not worth the trouble anymore I just leave it at home and I hate that I miss all my stations. HelPPPPPPPPPPPPPPP!!!

    I have an AudioVox that has worked for the past 3 yrs and certainly began displaying "antenna" problems. I have cleaned surface mount on top of the car and the spiral antenna boost. No change;, however, some mornings the reception is fine for about 30 minutes before it goes out.

    Question: Do antennas wear out due to exposure to weather?

    What would be my next course of action?

Lately I have been loosing the signal constantly in the house. I've tried different stations to see if it would be any better and it's not. I called xm and they refreshed my signal but it didn't do ant good. It's really annoying to constantly have the signal fade. Everything is hooked up right. This is been going on for about 5 months and my neighbors complain about the same thing.

Any Suggestions

Where did you place the XM antenna on the vehicle? It's possible you have a defective antenna, but you can try a different mounting location. It needs to be on the outside of the vehicle, preferably on a large metal surface.

Its because of the tall buildings and all the power around you breaking the signals.

I purchased a 2008 g35 infiniti & would like to know how to activate or operate the xm radio. thx

Turn the radio on an locate the Radio ID
For XM Radios

Your Radio ID can be displayed by tuning your radio to channel 0. (That's one channel down from the XM Preview.) Make sure to check your ID code carefully. Please note that the following letters are not used: I,O, S, and F.

Call the activation hotline to activate your service


Can't get refresh signal to work for xm radio

to reset the radio - it must be removed from the dash and unplugged.
Be sure to write down any anti-theft codes if your radio requires them.

However - since your radio is getting the 2 channels - it is working properly. The problem lies in XM turning on your account.

Be sure to get the correct # off the radio... sometimes there is a transposition error with paperwork.
The number can be gotten by setting your radio to channel 0. This is your radio ID# required to activate the radio.

Your Radio is working fine - call XM and stay on the line until they activate your account.

I have a suspicion the number was written down improperly.

Be sure when you call that the car is on, and that it is tuned to station #1... also - it can take 15-20 minutes to activate - and must be left on for the duration to catch the activation signal that is sent out.

Here are the steps from XM to activate manually-

Get Your XM Radio Activated Online

Step1 Turn on your XM radio and tune it to channel 0. The display will read your XM radio's identification number. This number will include both letters and numbers. Write this number down and head to your computer.

Step2 Log onto the Internet and go to the XM radio website. A high speed connection to the Internet will make this go faster, but you can activate your XM radio online with dial up.

Step3 Click on the tab that says to activate a new XM radio. This will take you to a screen where you will enter your XM radio's identification number. Type this in.

Step4 Choose a screen name and password to make an account on the XM web site. The screen name should be something that you will easily remember. The password needs to be at least 7 characters long and include 1 capital letter, 1 lowercase letter, and 1 number.

Step5 Enter your personal information for the activation of your XM radio. This information will include your name, address, and email address. You will also need to choose which service plan you will want to purchase for your XM radio. Enter your credit card payment to finish purchasing your activation of your XM radio online.

Step6 Turn on your XM radio and tune it to channel 1. XM will send a signal out to your XM radio to activate it. You will need to leave the radio tuned to channel 1 for 15 to 20 minutes to activate it.

If you have additional questions or concerns - please ask me first before moving on to another expert.
Thanks for using FixYa!!

How do i install the xm receiver?

Yes, the unit should have a FM mode where you can use it to transmit the signal over your FM stereo. The unit should come with a FM transmitter and it should be in the instructions on how to install it. All you have to do then is make the unit play on the same station your radio is on.

XM reciever FM transmitter problem

hi the xm radio hardwired installed? if it's a yes you have to go to a professional(bestbuy, retailers) to have the connection check.. the problem is not within the xm's on how it was installed or set up...

If the radio was not built..well, that's much better we just have to check the audio connection from you're xm to fm radio (make sure to check if what band it is connected..such as AUX,CD etc.) if there's a sound but you're only getting preview channels..refresh must be send on the can call xm to ask for that OR do it online at and type in your 8 digit radio I.D just have to follow the activation instruction faithfully...Godbless!
