I have a Stiletto and when I put it in the docking station I get a Antenna not connected, when there is a antenna connected to it! do I need a new antenna and where can I get one?

Sounds like it could be the dock itself, but could also be the radio. Do you have other docking stations to test it out in? If it works in one dock but not the other, we know its the dock that needs to be replaced. If it does the same thing in both docks it is probably the antenna connection in the receiver.

Does it get a solid signal when its in a docking station? Its likely that the internal antenna on the unit is disconnected. Antenna headphones would correct the issue, though they are not very durable at all. I know that our repair guy is able to fix the internal antenna, but I would ensure that is the issue first. Try plugging it into a home dock, car kit, or boombox to see if it works through one of those antennas.

Simple. Go to http://xmfanstore.com , click on "Antennas and Extensions" under "Shop Categories" on the left most side of the site; there you will find "XMFanStore XM2go Direct Connect Antenna Adapter" .

It plugs into the SIDE antenna port of your XM unit and you plug the antenna into that.

You may have a defective satellite antenna or cable

I've had this same thing happen to mine frequently - all I do to solve the problem is to remove the battery for about 20 seconds and then reconnect and power it back on. Always works fine after that (knocking on wood)! Hope this helps!

Try docking the unit without the battery attached. The unit will recycle and that may solve the problem. You will, however, need to continue to dock the unit without the battery...

The unit has an internal antenna (that is really poor) that is activated when you unplug the external antenna. This is why you get some signal when you unplug the unit.

I assume the problem is the antenna itself.

My suggesion is that you charge up the unit, take it to a place that sells XM equipment AND has a demo unit working. Be sure to take your docking station with you (it has the plug in for an external antenna). Ask the sales rep to please connect your unit to an external antenna to test your unit as you are trying to determine if your antenna is bad. If it works, you need a new antenna (cable may be cut on the inside or antenna may have water/weather damage). If it does not, then there is an electrical issue inside the unit and the unit itelf will need replacement/repair.

I have noticed various changes in my invehicle FM reception as well. There should be a external antenna that came with your car kit. This is precisely for these types of issues. It is designed to run along the windshield inside the car closest to the Cars radio antenna. It should plugin to the bottom of the cradle. Then tune it into a clean FM station (one that has no local station on it) and position the cradle and/or ext. antenna till you get the best reception in your vehicle. It could very well be that the antenna has come has loose on your car stereo backplane. You would probably notice decreased reception on regular AM/FM stations as well though.
Your wifi reception/functionality is a completely different animal and has no bearing on the FM transmitter in the car cradle. When your on wifi your not receiving signal from a sat. anymore just simply streaming internet audio like your computer.
Good luck.

You cannot adjust the volume when the stereo cord is plugged into the back of the dock. Instead, plug the stereo cord into the front headphone jack of the dock. You will be able to adjust the volume then.

Satellite radio antennas do tend to fail sometimes. In the early days of Sirius/XM they were made a lot better, but now I've had problems with them a lot more frequently. If the antenna is plugged in securely and it still shows the 'antenna' error code, you most likely need to replace your antenna. It is possible that something else along the antenna signal path is causing your problem - Sometimes the antenna connections in the dock or the receiver itself can cause the issue, but most likely it is the antenna.
