How to Connect Phone to Car Speakers Without AUX

Getting new speakers for your car that sounds is great and all but the problem is that many cars doesn’t offer a way to connect your phone. That means that your new speakers will not play anything other than the normal radio and how fun is that? For this article, we are going to take a look at the different options you have if your car doesn’t support any kind of connection to your phone.

Getting new speakers for your car is fun and all. But these speakers will not be utilized as they should until you have solved the problem with listening to your own music. In 2018, most of us use Apple Music or Spotify but the problem is with older cars, who doesn’t feature Bluetooth connectivity. Some of them are offering AUX but with more phones dropping that, this is an increasing problem even there. So, let’s solve that problem once and for all today. Here are some of the best solutions for connecting your phone to car speakers without AUX.

Using an FM Transmitter

The cheapest option is to get an FM transmitter. The way it works is that the transmit signals to the car stereo using radio frequencies. You set the same frequency on both the transmitter and the car radio and once you connect the transmitter to your phone, you play music this way. It’s simple and easy to use.

The transmitters themselves come in different variations. You can get cheaper transmitters that you hook up to the headphone jack, but since we no longer have headphone jacks on our phones, that is out of the question. Instead, we have to use wireless technology, Bluetooth.

The Nulaxy Wireless In-Car Transmitter is a Bluetooth-device. You connect it to the 12V output in your car and then connect it to your phone using Bluetooth. This way, your phone will play its music to the transmitter and the transmitter will then forward this to the radio in your car. The Nulaxy device is also great in that it has buttons on it that you can use to control the music with, like switching songs back and forth.

Going with a solution like this will be the simplest way to connect your phone to your car stereo. It’s easy and it’s cheap. You don’t have to mix around with the cables in the back of the head unit.

Disadvantages

But there are disadvantages to this solution as well. Since you will need a free frequency on the radio, it can be a problem during longer travels. A frequency that is free in your city might not be free in the other. It’s also common with disturbances from other electrical things and it also tend to break a lot in signal. I would say that Add choosing an FM transmitter should be temporary or for a one-time use. If it should be permanent, I would recommend another solution.

Getting a Car Adapter

A third option is to get a car adapter. This adapter will be connected to the CD-changer output on the back of the of the original head unit and will then trick the head unit that it’s a CD-changer while being something else. For this solution to work, you will need to know if you have a CD-changer output on the back of the head unit, I’d recommend checking the manual for your car.

There are many different models of adapters, all with different functions. Some of these adapters have only AUX and USB while others will also support SD-Cards and Bluetooth. To give you an example of an adapter, you can check this Yatour Bluetooth Car Adapter. This specific one is for Honda but you can find many others models specific for your car. This is something that is really important since there is no standard for CD-changer outputs so all connections will look different, make sure you get one for your specific car.

Disadvantages

There are very few disadvantages to this solution. One would of course be if you don’t have a CD-Changer output on the back of your head unit, then you will have to go with any of the other solutions. Once again, you should feel comfortable to dismount the original head unit since the connector will be on the back of it. You will also have to store the adapter somewhere and route the cables to where it should be. Other than that, there isn’t that much.

Changing Head Unit

Changing head unit in the car is the best option, as it would integrate the connection in your car, it will look nicer and you will most likely get other benefits as well. However, it’s a bit more complicated and more expensive than other solutions. Today, most head units will come with both Bluetooth and USB port(s). Both of these can be used for listening to your own music and using USB will also charge your phone at the same time, which is nice.

Choosing the best head unit can be tricky, as it will depend on budget, features and what not. To help you out, we have created a double din head unit buying guide which you can use to find one that you like. If head unit is something that you would like to get, I highly suggest that you get a double din as it opens so many more doors. Ever wanted navigation in your car? You can get that with a double din.

Disadvantages

As mentioned, the big disadvantage with buying a new head unit is that it can be much more complicated to install. If you are unsure of how electric wires work or not willing to disassemble your car to mount a new head unit, this is out of the question for you.

It will also destroy that original feeling, as most old cars didn’t have a 6”-screen in the dash from the beginning. If you are the one who loves your original dash, this might not be for you. On top of that, it’s not to say that it will be more expensive to get a new head unit. On the other hand, you get much more than you would get from a transmitter.

Conclusion

As you can see, there are quite a few options to choose from when your phone or your car is missing an AUX port. While getting a transmitter is cheap, getting a new head unit is the best and most stable solution. In my old car, that didn’t have any connections, I bought myself a car adapter as I wanted to keep the original stereo in the car. It worked great for the time I had it, until I bought a car with built-in Bluetooth.

But buying a new car might be a bit over the top just to get your own music, don’t you think?
