My cars satelite radio will only function on FM

Check the connections between the head unit and the XM tuner. If the connections are good check for power and ground.

Yes, many of the channels are now the same and you will pay a little bit more for an additional package called "Best of XM" to add some XM-specific channels to your Sirius radio.

You need to subscribe to Sirius Satellite Radio. Call them at 1-888 539-7474 and they can walk you through the procedure. Once you start listening to satellite, you will never want to listen to AM/FM again.

The audio plug overrides the FM frequency setting. That way if you use a tape adapter to run the music through it will use that source instead.

A lot of FM channels are getting crowded into a lot of markets out there. The best way to fix the problem is to use a direct FM module. This way your Sirius will override the FM channel whether it is used or not.

Here is a link for one:

they are very easy to install.

Most of the New Aftermarket Stereo's now have the Connections for Sirius and XM Built in so you just need the Sat. Install Box. Really Simple. If you want to go a Cheaper Route Just Purchase the XM or Sirius Reciever and Mounting kit for the Dash or Windshield and It will play through an Empty FM Station on the Radio Via the FM Transmitter. Got one in all of my Vehicles and they work Great!

satellite reception problem

You can get a Windshield Mounting kit and Sirius Unit and use the FM Frequency Modualator that is Built in and just not use the XM.

Any Radio will work with Sirius if you use the FM feature and tune your radio to 107.1

Sirius radio connects via a special dock. Sorry, but you're screwed with your XM unit...
