How to Get Bluetooth in a Car Without AUX?

There are four ways to connect your phone to your car’s head unit or stereo without using AUX or Bluetooth: 

Use an FM Radio Transmitter

An FM Radio Transmitter is a device that can connect your phone to the radio that’s already installed in your car. For example, if you have installed a car radio in your car, you can use an FM Radio transmitter to connect it to your phone. 

Just buy an FM Radio transmitter online or at a nearby electronic store. Then, turn the radio on in your car. Next, connect the transmitter to your phone’s headphone slot. Now, any music you play on your phone will be played through your car’s speakers.

Use a Cassette AdapterWant to know how to get AUX in an old car? You don’t need to if your car has a cassette slot available. Most old cars come with cassette slots. You can get a Cassette Adapter & use it to play music through your car’s speakers. Connect the adapter to your car’s cassette slot. 

Then, insert the cassette adapter’s 3.5mm jack into your phone’s headphone slot. Now, on the cassette slot, look up an option titled “tape.” Select this option from the audio system’s menu & start playing music via your phone & through your car’s speakers.

USB input

Suppose cassette adapters offer the perfect alternative to AUX for old cars. In that case, USB inputs do the same for new models. Most new-age cars come with inbuilt USB ports. You can use these ports to play music from your phone & through the car’s speakers. Just get an extra USB cable. 

Then, connect it to your phone on one end & to your car’s USB port on the other. You’re guaranteed to get a reliable connection that doesn’t just produce good sound quality audio but also facilitates phone charging. 

In addition to charging your phone, you can also take calls while driving. So, a USB port is essentially a better version of an AUX for a car without AUX. But what if your car doesn’t have a USB port? Then, you’ll need to buy a USB Bluetooth adapter for car without AUX. 

Hands-Free Bluetooth App

This solution is becoming increasingly popular among new-age car owners who want to add Bluetooth to car without AUX input. Many new-age cars have built-in Bluetooth properties. This type of Bluetooth is known as a “hands-free Bluetooth call.” 

Car companies have given owners the ability to connect their cars to Bluetooth without requiring any intermediaries. If your car happens to have this feature, you should download an app that’s designed to activate this feature. 

mySPIN, CarAuto BT, Car Connect, etc., are some apps that are specifically designed for this function. Download one on your phone to play music through your car stereo. Of course, you can use the hands-free mode for calls as well. 

How to Connect AUX to Car Without AUX Port? 

You can add Bluetooth for car without AUX by getting an FM transmitter. Just plug the transmitter into a power socket in your car. Then, connect your device to the transmitter via cable or Bluetooth. 

Now you can use Bluetooth to play music in your car via your phone without requiring an aux input. Here’s a helpful video that demonstrates how to setup & use an FM transmitter in a car that doesn’t have an AUX port or Bluetooth:
