An FM transmitter is a great device that allows people to listen to their favorite music or audio books in their car. These devices hook up to a smartphone or MP3 player and, as the name implies, wirelessly transmits the sound through these devices to the head unit of the vehicle.

Getting The Most Out of an FM Transmitter
FM transmitters are wonderful inventions. They allow users to break away from whatever radio stations are in the area and play their favorite music or audio books through their car’s head units. And to accomplish this task, all that’s required is finding the best transmitter and taking the time to set it up properly.
Unfortunately, this is where some people have difficulties. They either buy a transmitter that’s not right for them, or they fail to set it up properly That’s why we’ve decided to offer this basic guide on getting the most out of a modern FM transmitter. Let’s start with the basics.
Get the Right Model
It’s important for a consumer to pay attention to the features found on the FM transmitter before buying it. Ideally, they would buy a transmitter that allows for manual tuning. This is important so that local FM interference can be avoided. Some of the more inexpensive models don’t give the consumer this option. Instead, they only give them only a handful of presets or automatic tuning. This doesn’t give the user enough options to be able to allow the broadcasting of their signal without interference. This can result in all kinds of different connection problems.
Input options are another thing that has to be considered. The majority of the transmitters available connect with a simple audio jack that’s connected to the 3.5mm jack of the MP3 player or smartphone and if that’s all the user needs, then that should be pretty easy to find. However, if the user needs a different connection method, then they are going to want to find the best model possible that offers that particular input. Some transmitters can be connected via Bluetooth, others have inputs for USB devices or SD cards. All it takes is a little bit of time to find these models.
Checking the Dial
One of the first things that have to be done when the transmitter is first set up is to sync it with the head unit of the vehicle. This means placing the transmitter and the head unit on the same channel. While this may initially sound pretty easy, however, it can be a big pain in heavy populated metropolitan areas. That’s because most of the FM dial is populated with radio stations around big cities, so it can be difficult to find a channel that doesn’t have interference. Fortunately, it can be done in all but the most populated areas.
Often times, the beginning of the dial and the end of it are the best places to find an empty frequency. After all, below 93 MHZ and above 106 MHZ are usually the parts of the dial that are likely to be the emptiest. Work from the beginning and work towards the end to find a frequency that’s not being broadcast on by a radio station.
Fine Tuning the Signal
Just because an empty frequency is found on the radio dial, it doesn’t mean that there isn’t going to be any interference. Powerful stations can often have a profound influence on the frequencies around the one they’re on. That’s why it may be helpful to look around a bit. A station may use the 94.6 MHZ frequency but interfere with the 94.4 MHZ frequency which is otherwise empty. The user may have to work their way through the frequencies 0.2 MHZ at a time. If it’s impossible to find a clear range of channels, then the user may have to choose the one with the least interference.
What if it Still Doesn’t Work?
For the vast majority of people, setting up an FM transmitter is pretty easy. However, there are circumstances where the FM frequency landscape is just too overpopulated. In those instances, the user may have to try something a little bit different. If they still have their heart set on an FM transmitter, then they may have to remove the antenna from their car entirely to use it in heavily crowded FM landscape. If they don’t want to do that, they can also try replacing their head unit with another one that allows the antenna to be turned off. When neither of those options is viable, then the user may just have to use an FM modulator to transmit their music or audio books.
Buying an FM transmitter and setting it up isn’t all that difficult. And there’s probably no better time to buy one of these devices because most of them are packed with a ton of useful features that make them useful to just about anyone. They’re a good option for consumers who don’t want to have to depend on their local stations to deliver the music they want to listen to or want a device that will allow them to play their favorite audiobooks.
