No antenna detected

Check your antenna. If the mast is not extended, your reception will be limited. try an AM station, usually a local AM station will still come in even with the mast down. Have you tried playing a CD (if equipped) ? If that plays well, you've confirmed lack of reception as the problem. If the mast is extended and you still do not have reception, the antenna plug my have come out of the back of the radio. The requires removing the radio to check.

The "hard wired" version that you speak of apparently only refers to the power supply.Do you have a seperate display for the Sirius unit? Now, you failed to mention the type of radio (factory or aftermarket); so, if you have to use an "empty radio station" then you have an FM modulator. This modulator could wired or wireless. The wired version interrupts the vehicle antenna wire and the station on said modulator is usually preset to either 88.1, 88.3,88.7, or 89.1. There is no need to power this modulator up, it comes on when then Sirius comes on. One way to check for power is to turn on the Sirius unit and tune your radio to an occupied Fm station. Wait a few seconds and listen to the reception. Turn off the Sirius unit, the reception should improve for the occupied station. If it is a wireless FM modulator it also has preset stations that you can change but, extending the wieless antenna will greatly improve your reception of the Sirius stations.

First of all check for any nearby source of interference.....Move your unit away from all computers, fluorescent lights, neon lights, microwaves, cell phones, and cell phone chargers. These devises tend to produce noise in the medium frequency band, where AM radio is broadcast.
If the unit plugs into the wall with a nonpolarized plug (where both prongs are the same size), try reversing the plug in the outlet. Moving the plug to another outlet might help, too.
check for fault in the antenna lead, (common) or bad earth on the antenna to body
If you don't have an antenna connected to your FM receiver,With a receiver or tuner, connect a wire-loop or T-shaped dipole FM antenna to the back of your unit. Move the antenna until you get the cleanest signal. Use a signal-strength meter or display to gauge signal strength if your unit has one.

Step 2 If you're still not getting a good signal, try an indoor amplified antenna, which you'll find at an electronics store. Don't buy one unless you get a guarantee that you can return it for full credit if it doesn't solve your reception problems.

Step 3 If your signal is weak because you live a long way from the transmitter, install an outside antenna and mount it as high as is practical. If you're primarily interested in getting signals from one station or from a group of stations in one direction, get a directional antenna and point it toward the transmitters.

Step 4 If you're using a portable FM radio where the only antenna is the power cord, stretch the cord as straight as possible and experiment with positioning again.

Step 5 Temporarily switch to monaural mode to improve a weak signal on an FM receiver.

Step 4 With a receiver or tuner, connect a wire-loop or T-shaped dipole FM antenna to the back of your unit. Move the antenna until you get the cleanest signal. Use a signal-strength meter or display to gauge signal strength if your unit has one.

Step 5 Alternatively, upgrade to a third-party passive or powered antenna.

Step 6 Install a rotatable roof antenna for the best possible reception. Connect your unit to an existing television roof antenna for the next-best alternative.

HI there,

Well Yes you can improve the reception, please follow the below steps -

Improve FM Radio Reception -
 
1. If you don't have an antenna connected to your FM receiver, purchase a simple dipole antenna--a simple T-shape flexible wire-- and connect it to the FM antenna inputs on the receiver. Because FM signals are directional, you'll want to experiment with the positioning of the wire to find the best reception of the station you're trying to receive.
 
2. If you're still not getting a good signal, try an indoor amplified antenna, which you'll find at an electronics store. Don't buy one unless you get a guarantee that you can return it for full credit if it doesn't solve your reception problems.
 
3. If your signal is weak because you live a long way from the transmitter, install an outside antenna and mount it as high as is practical. If you're primarily interested in getting signals from one station or from a group of stations in one direction, get a directional antenna and point it toward the transmitters.
 
4. If you're using a portable FM radio where the only antenna is the power cord, stretch the cord as straight as possible and experiment with positioning again.
 
5. Temporarily switch to monaural mode to improve a weak signal on an FM receiver.


Improve AM Reception -
 
1. Gradually rotate the radio 360 degrees. Leave it in the position where it sounds best.
 
2. Reverse the AC plug if it isn't polarized. (If you can flip the plug over, then it's non-polarized.)
 
3. Plug the radio into a different AC outlet.
 
4. Move the radio closer to a window.
 
5. Experiment to learn if appliances and powered products in your home are causing interference: computer monitor, television, electric blanket, light dimmer, fluorescent light, hair dryer, air conditioner, smoke detector. If possible, turn off the offending item. Otherwise, move the radio to another room.
 
6. Upgrade to an external antenna if your receiver, tuner or radio has a place to connect one.
 
7. Buy a passive AM antenna that doesn't need to be connected to a radio or receiver.

Good Luck!!

Thanks

Reception has little to do with grounding. The ground plan is for transmitting. As long as the coax is connected and is in good standing, it should receive fine regardless of grounding.

There are a few reasons you may have bad reception.

1. Turn the RF GAIN all the way up. This is your receive sensitivity.
   
2. Squelch is too high. It should only be turned up enough to cut out the background noise.
3. Poor antenna. If the antenna is cheap, and not made well, this could be the problem.
4. Not enough of the antenna above the vehicle. It needs to be at least 60% of the antenna above the vehicle.

Hope this helps!

I was having the same problem with a jvc kd hdr 30. I Installed it myself over a year ago and never wanted to deal with the issue. Finally, I decided to take a look at it today.
On my head unit, all wires were connected except one blue one with a tag that says "do not connect to power, for remote device or power antenna only." This unit is in a '97' MBZ E320 with no visible antenna; I think it is part of the windshield. In any case, between the wiring diagram in the manual and the harness that is part of my car, I was left with 2 blue wires to choose from, one with a white stripe and one with a gray stripe. After testing both for power or ground, I determined neither had power with key on or off. Both had high resistance ground when compared to the chassis ground. In other words, I measured between chassis and these wires. First, I took a wire and connected it to the chassis ground and connected the other end to the blue wire coming from the unit while tuned to a local am station. This simply killed all reception am or fm but did not harm the unit. Next, I connected the blue wire with gray stripe of the car harness to the blue wire of the unit and again this killed all reception. Then I connected the blue wire with white stripe of car harness to the blue wire of unit and presto magic I had great am reception.
I am guessing that this blue wire with white stripe must be part of the antenna itself or perhaps is a connection that increases antenna power. Maybe 'power antenna' on tag refers to an actual powered antenna (like as in amplified?) and not as in an antenna that rises up out of fender, as I believed.
This may not help the first person with the question, but maybe it will help someone out there who searches for these kinds of answers like I do from time to time.

Sounds like you have an antenna problem. Find where the antenna plugs into the radio. Unplug it and find a nail or something the same diameter as the center pin wrap about 3-5 turns of a four foot piece of wire around the nail and plug the nail into the antenna input on the radio. If it clears up reception you have a bad or grounded antenna. Follow the antenna wire back to the windshield or fender etc. mounted antenna, sometimes there are other plug in points that get knocked loose.

The headphones are the antenna, you may have to walk around to get better reception. I've never found the radio reception to be great on t. A full manual is available for this product on Sandisk's website.

Turn on the radio and turn the AM/SW BAND switch to the AM position. MW appears in the display. Use the outer ‘fast’ tuning knob to find stations, fine tuning with the inner ‘slow’ knob
when needed.

• If there is interference from adjacent stations, place the BAND WIDTH control in the NARROW position. If there is no interference, leave it in the WIDE position.

• If there is excess background noise, turn on
the SW LPF switch, which may minimize the noise.

• If a station is so strong that audio distortion occurs, reduce the gain level with the AM/SW RF GAIN control knob by turning it counterclockwise.

• The telescopic antenna does not have to be extended for AM reception. The radio has an internal, directional, ferrite-bar antenna for AM reception.

• To optimize AM reception, swivel the radio until maximum signal strength is achieved.

All of that being said: It's very tough nowadays to receive AM in this 2008 electronic world. If your able install a longwire SW antenna outside, and have access to a good earth ground, you can boost the AM signals and beat the noise being generated all around you.

Hi, to all. There are currently two types of Bose Wave Radio system available in the market. The first one being the WRCD with the top loading CD mechanism. This unit does come with the Antennae cable inside the box and this should sort out your problem. Another option is using an outdoor aerial antennae and connect this to the antennae port behind the unit. The second one is the new Wave Music System with the front loading tray mechanism. This system uses a unique concept of using the electrical cable included in the box and utilise your electrical pwoer line as the antennae receptor. I recommedn to keeping the pwoer calbe fully extended. Another solution for this is that Bose service centers do have a specific spare parts calbe called the AM/FM antennae cable for WMS which you can simply buy for around 20$ I assume. this basically bypases the power calbe and routes antennae reception through this minicable (brownish colored RJ calbe).

Glad to be of service...
