These days many cars come equipped with a USB port for an auxiliary input so that they’re able to connect to an external device such as a smartphone or MP3 player and use it for playing music.

For those using an older car, like with my 2002 Volvo S60 , you might not have a USB port or an auxiliary input and in this case you’re going to have to either use CDs (that’s if your car comes with a CD player) or you’re going to have to consider using an FM transmitter.

Without one of these transmitters you’re basically stuck just listening to the boring radio and this can get quite tedious quickly because of all the ads and music that you might not like.

Having an FM transmitter will allow you to connect it to a smartphone or mp3 player where you’ll then be able to play music, audiobooks, or podcasts through your car radio system on any FM frequencies that aren’t in use.

This kit can be used for using smartphones and MP3 players for listening to music over your car stereo if you don’t have an auxiliary input or USB port in your car.

To get everything working you have to plug in the 3.5mm audio plug into the headphone jack of the device that you want to use and then with the digital tuner you need to tune to a station that’s not being used so that you’ll be able to play music over it.

Depending on where you live, especially if you live in a busy city area, you might have a little trouble finding stations that aren’t used but if you go through the different frequencies you’re bound to find one that will give you a suitable connection.

One great feature I love about this kit is that the car charger plug that powers the digital tuner also comes equipped with an additional USB port so that you can use it for charging your smartphone or other device while you’re driving.

I love using it for my iPhone, especially when I’m using GPS, because I’m able to listen to music and keep my phone charged at the same time while being able to follow directions so that I don’t get lost.

Depending on your preferences there are a few different colors to choose from and overall I would recommend checking out the JETech Wireless FM Transmitter Kit if you’re looking for an easy and straightforward way of being able to play audio devices in your car through its own stereo system.
