A/C Adapter Noise and Interference

I have Three Roady XT's that A/C adpaters have failed. All have a high-pitched noise and warm to the touch. One adapter has failed causing the radio to power-up and shut down. Are there other Delphi customer experiencing this problem? The only fix is another adapter and a aftermarket/universal adapter may be hard to find.

    I am having a noise problem too. When I turn on the radio with the AC adapter there is a high pitched buzzing noise. I have not been able to locate a new adapter yet.

    The AC adapter in home kit makes high pitched terribly annoying noise.
    I hooked the car charger into an AC adapter and it does NOT make the noise anymore....so its in the ac plug in.

AC wall adapter was failing for me. Car adapter worked OK. Found a 2A 5V adapter and changed the connector with success. Again hearing occasional beep but in car, no explanation found. Have had several good years of service; should not complain.

I found the problem lies in the XM adapter after replacing with a new one. I went to Radio Shack, purchased an Enercell AC to DC power adapter with the switch on 5V and an "N" 273-188 Adaptaplug. Voila! No irritating buzzing noise. Not cheap, but did the trick!

I just got my radio and home kit today, the hi pitched noise is awful so I looked online and found you.  I finally hooked the car adapter into a wall plug adapter and volla- NO NOISE!  Whew. It's a $9 adapter I got for my ipod car adapter....just has a hole to plug in the car adapter and you plug it into the wall.  
...good luck

Just wait until you're over 60; my kids can hear the high pitch, but I can't! You could try another power supply, but it has to have the 2000MA or 2AMPS of power to fire up the unit.

I had the same problem. Worked around it by going through the cassette tape adapter. Seems to have solved the problem.

I am also on my third adaptor and I have yet to listen to the Roady for more than 2 hours total over 6 months. I have tried to find an after market adaptor without success. I can find only a 2500 mA adapter and that won't power it up. Any suggestions?

We should sue Delphi for resolution of this problem. I feel that the adapters are a fire hazzard.

My Dell inspiron 13r laptop is emitting a very high pitched noise when it is on. I have tried reinstalling my audio drives but nothing seems to be working... Please help

If it is a relatively quiet, high pitched noise, it may not even be from your speakers. I've experienced a high pitched noise whenever i plug in my AC adapter to my PSP, so there is a chance it might be power related.

I can hear a soft squealing noise when my Roady is in the home dock. Also it starts changing stations randomly by itself. Any suggestions?

If you're using XM Direct to input channels, press the select key after tuning to the channel. If you're not, perform a factory reset. The squealing noise is because of interference with your speakers, it's normal (unless you don't hear any music).

Delphi Roady XT. Changes channels by itself. Can I fix that?

Try a new wall plug/adapter. You need the 5V adapter from Belkin. Worked like a charm for me--after suffering with this problem for a week....only cost $10.

High pitch sound in background

A high pitch sound while connected in the house is either a problem with the reciever or you are picking up interference from somewhere. However, the high pitched noise when using the unit in a car (especially through an aux. connection), is caused by the alternator of the car. This can be eliminated by connecting a filter in-line with the aux wire (much like filters are installed on the radio power line). The filter is essentially a low pass filter that filters out noise above a certain frequency. You may have to get creative and modify your aux. input cable (i.e. - splice it into the aux cable) in order for this to work, or you can just turn the volume down a bit - it should be less noticeable at lower volumes.

High Pitched Sound

I am to believe that your static sensor on the playing head is touching the the head and it sould not. just bend it up "slightly" and the noise should disappear

Delphi Roady XT Quit Working

Chances are it's not picking up the XM signal. First, contact XM to resend your setup. if that doesn't work check your antenna connections.

Noise with casette adaptor

Well Jill the problem you are having is called inducted noise. The lighter power adapter cord is inducting electrical current to the cord used by the cassette adapter thus creating the the noise you've been hearing. Do your best to separate the two cables as much as possible. I realize that your unit may have both cords coming out of th same side, and that's fine. the longer the run of wire, the easier it is to have induction issues. If the cords do come out on the same side, run one up and the other down away from the other cord. Do not coil the lighter adapter or cord either, it increases the chance of being able to induct noise. If your unit is to close to the lighter assembly you may need to move the unit to another location in the vehicle itself to help combat the noise issue. Other options include to shield the cassette adapter wire, i use aluminum tape for heating/ac ducts. The only other option i can see is purchasing a FM modulator which will transmit the units sound wireless-ly through an FM radio channel. You will want to check and see...i do believe most XM radios have a FM modulator built in. Hope this helps, and good luck.

High pitch noise when tv warms up

High pitch noise is created mostly by a Coil or a transformer,is not easy finding the source if you are not familiar with this type of coil since there many sizes and shapes,the set needs to be on while trying to find wich part is doing it SO if you dont know where and how better call a Technician and you will be safe.
