Question: It looks like a standard 3.5mm plug.  Could I use this with my iPod?
Document: Bought it for our boat, antenna plug was easy. Now here's the BUT, it comes with a 2.5mm plug. everything including our XM has a 3.5mm plug. For $5 I bought an adapter.
I had this professionally installed, so I can't speak to any do-it-yourself people. Also, it cleaned up alot of the wires i had running around the dash and i have my cigarette lighter back as a power source.As an interesting sidenote, I also use an FM transmitter for my Zune and it sounds like there is less static on that as well. Could be coincidence, but I'll take it.
This is a must have if you have a SiriusXm Radio in your car and don't have an AUX port (where you plug an ipod into), This turns your antenna into a AUX port.
You do have to make sure your antenna wire will work with this adapter. It is the standard antenna plug that has been used forever on car radios. The install took me all of 10 minutes while waiting in a traffic jam. Oh, I finished the wire routing later, but that took all of 5 minutes as well. Get this. Thank me later.
The product has good build quality and the installation is very simple. I bought this product without doing full research. My main intention was to use this as an AUX input for my factory stereo. Sad to say it doesn't work with any mp3 player or iPod or phone. The technology that's being used has to do with RF signals. If you are looking to hook up an mp3 player through the rear radio input, what you really need is a FM modulator.
Sound is now crystal clear without any static or interruptions. There are no other inputs into this device, so if you want to hook up an iPod as well and play through your factory radio, you will not want this device. For the Tacoma, a company called USA Spec makes a nice adapter that functions like this device but also allows an input for an iPod.
Definitely a must have. Say good by to the static caused by the standard FM setup. That use to really annoy me.
The instructions say you might need antenna adapter but this was not the case for me. I know you will not need the antenna adapter for 99-02 Mazda Protege, 03 and up Mazda 3 and 03-12 Mazda 6. I own these cars and I know they have the same radio connection. This will more than likely work for all other Mazda as well since they don't change much when it come to the connection they use.
This item is described to fit any manufactures antenna. My stock radio in my 2000 Chevy express van  has a shorter, smaller diameter antenna plug. Both plugs on this adapter are to large to work. I was forced to buy two antenna adapters at a cost of $21.10. Which is more than I paid for the adapter. I encourage people to check there antenna plug before buying this item. If the outside of the plug is about 3/8" it will work.
This product works fantastic! I live in an area where the FM stations are close together and have a lot of trouble getting a dead area to use. This unit completely solved my problem. However the area you check vehichle fit is not accurate. My 2003 Dodge Caravan will not fit without some adapting. The standard adapters cost as much or more than I paid for the unit. The unit uses Motorola type rf connections where as the Chrysler products have there own thing that is not even close.
Answer: No!  This does not convert the signal used to drive standard earphones into an FM signal.  The Sirius, XM, and SiriusXM satellite receivers have built-in FM transmitters.  This device just couples the output of the transmitter directly to the antenna of your vehicle to avoid interference.
