using sirius/xm without an aux port

Well if you have a cassette player, you can use an adapter and plug it in to the back of the dock the radio plugs in to. Or you can buy this little black box that eliminates outside radio frequency. On one side you plug the antenna jack from the antenna and there's a cord on the other side that plugs into the radio. Then there's a smaller plug that goes into the back of the radio dock that I guess power it or something. It works well to eliminate outside frequencies. I only have to change the radio station once or twice to a more empty station to get a clear reception.

 

they call that antenna adaptor Sequoia explains a FM Modulator Adaptor or a FM Direct Adaptor, aroun 15-20 bucks, works well in my truck

 

You can purchase a FM adapter from a truck stop for about $25 dollars. It plugs into the sirius/xm radio and the other end goes into the back of your radio. Most radios can be pulled out enough to plug this in. You might have to ask another driver who has the same truck and radio as you or call the truck manufacturer and ask them. We had a 2007 Freightliner with no outside auxillary so we had to go from the back. Once we got it all hooked up and bought us a $40 mirror mount antenna for sirius/xm radios....we NEVER had to change the channel again and the sound was great!!

I use the cassette adapter.

 

If you feel you may be in the truck for a while, you may be happier going to some major truckstops or a dealer for your particular truck and by an XM or Sirius ready radio, pull out the old one, save it, and stick in the new one and get the antenna to the back of it. It's integrated and not in the way and wiring is limited to only the antenna. (Your truck may actually be pre-wired for satellite radio and have an antenna somewhere wired to near the rear of the radio)

Many of these radios are "universal" but to be sure, pull your factory radio out and look to see what type of main harness plug it has before buying another.

 

the xm sounds better transmitting wirelessly to the radio. no need for an adapter.

the drawback is the jesus channels cutting into my braodcast. and i've tried various channels. so i stick with aux port.

the drawback with the aux port is the slight whining from the alternator.

i have a splitter wire so i can plug both my phone and xm into one port. when i want to use my phone as a mp3 player. i disconnect the charger to get rid of the whine.

 

You have a ground loop. Try running a wire from your cigarette lighter's ground to the ground on your radio, this should fix it. Or buy a radio with built in satellite, which gives the best sound and least hassle.
