One of the most common questions I get since iPhone 7 came out. " Where is the dongle? " " Where is that little wire ? Where is the dongle? "
Here is a demonstration video showing you exactly where to find the dongle that came with your iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus and iPhone X.
Here is quick walk thru of how to set up the gadget. It works on all home or car radio, and the process are the same.
The phone must be naked without the protective case. Make sure the transmitter is plugged in all the way to the headphone jack with a snap. The transmitter needs to make a full contact thru the audio jack to get the best sound and performance. If you have a thick protective case like an Otterbox or Life Proof Case. It may be a good idea that you invest $9.00 ( anywhere ) for a dongle from the Apple store. This dongle / extension is made for the iPhone 7 and iPhone 8. However, it works with the iPhone 6 and iPhone 6 Plus just as well. It adds the conveniences of using the transmitter without the issues with the protective case. It is well worth the $9.00 in this case. DO NOT get the cheaper stuff from Amazon or Ebay. They DO NOT WORK.
Alternatively, you can also use a Y-Splitter ( about $3.00 ) from Amazon or Ebay.
The iPhone 7 or above has NO HEADPHONE JACK. It DOES come with a small extension wire / dongle in the box ( you can find it attached to the back of the headphone ). This wire allows you to connect the newer headphoneless iPhone to the standard 3.5 mm headphones.
Yes, You will need a splitter from Amazon. Please make sure it has MFI ( made for iPhone ) logo on it. It will not work and you may lose some function so please read the fine print prior purchase. MFI means it has been certified by Apple as a compatible accessory. It is usually much more expensive, but it's worth it without the frustration of something that is CHEAP and DO NOT WORK or Die shortly after you use it. DO NOT GET THIS FROM EBAY..You will be SAD and SORRY.

Sound transmission through the FM radio waves is a tricky business. ( This is one of the reasons why the major manufacturers DO NOT feature it on the smartphone.) There are many factors that could result in your sound transmission to be less than ideal. Your vehicle and location are all important variables. I've personally tested on hundreds of different vehicles to make sure that this gadget is compatible with most vehicles and the sound is at it's best quality.
Make sure the volume of your iPhone is set at about 60% to 80%. Max volume or low volume of your phone will cause distortion and interference to your sound. You can set the volume thru your car radio.
Extend or Telescope your car antenna if possible. Changing the angle or direction of your antenna could also improve the sound quality dramatically.
If you are in an area where there is more static interference. Try this! Attach the USB charging wire and let it dangle. ( this is the same as extending the telescoping antenna on traditional radio ), which will boost the radio signal up to 30% and improve the sound quality.
The bulit-in battery will take around two hours for a full charge, and it will typically last 8 to 10 hrs of play time depending on the usage. As a good measure, charge the transmitter overnight the first time, and charge it when needed thereafter.
The transmitter has built-in smart battery. When it detects the sudden surge of voltage in the car charger. It will shut itself off to protect the battery. ( Works much like the surge protector ). When this happens the transmitter will appear to be dead and the battery will not take charges anymore.
To Reset: Simply charge the transmitter thru your iPhone, iPad or iPod charger, or USB charger on your computer ( not in a car ). It will reset itself and works as normal again.
While you can charge the transmitter by plugging it into the cigarette lighter with the USB wire. It is NOT a good idea.The cigarette charger in your car is unstable which causes the battery to seize. Remember to unplug the transmitter from charging when you first start the car.
Always use the USB 1A charger that came with your iPhone, iPad, iPod or USB charger on a computer. DO NOT USE 2.01A USB (faster ) charger. The higher voltage will cause the transmitter to sezie up and damage or reduce the life of the battery.

Is there anything I can do to extend the transmission quality and range ? The RF ( radio frequency ) is all about the antenna. If you can improve the antenna, you can improve the reception. Just as you do with the rabbit ears for the TV antenna. Boosting the power of an FM transmitter beyond certain limits has legal consequences. Check with the FCC in USA, or the "Spectrum Direct" branch of Industry Canada as applicable, to find out the restrictions.
Additionally, try not to place your phone or the transmitter near another electronic device. If you have other add-on electronic device like a GPS. Please turn it off, or place your transmitter away from those devices. BEST OF ALL..... You can use this device anywhere there is an FM radio. You will get the same high quality sound this device is known for. You can use it with your iPod and iPads too.
As mandated by the FCC or your local equivalent. In the USA, the rule requires an ERP of 0.01 µW, or 10 nW, or -30dBm. So ok, you're only going a meter or so, so that signal at the car's antenna should be around -40dBm to -45dBm, depending on the actual distance. And a typical consumer FM receiver should be good to -90dB or so receive sensitivity. When it comes reception and sound quality. It's all about the antenna! Where's your antenna? Where's the FM transmitter? Chances are, the answer to the latter is "somewhere near a DC outlet". So if you have one of those in-windshield FM dipole antennas, you might have a pretty good signal, though the direct path to your antenna might be through your dashboard. But if your antenna is one of those shark fins on the roof, you have a 5-10 millimeters of steel between your transmitter and your receiver. The final sound quality will be degraded accordingly. The FM radio band is essentially a “line of sight” band. To hear a signal, you have to be able to see the tower. FM radio does have some power to penetrate buildings and the like, but ultimately the maximum distance that can be achieved is mostly set by the curvature of the earth. But on the “medium wave” band, radio waves can be ducted and can curve around the earth, especially at night.
FM radio sounds so much better is that the extra space effectively allows them to send more data. Without getting technical, they have 20x as much space, and so can send not just a wider range of audio frequencies, but also stereo sound, and other more modern improvements like the .
