How to Convert Normal Music System to Bluetooth in Car?

Gone are the days when we used to carry a stack of CDs or connect AUX cables to enjoy music in our cars. With today’s technology, Bluetooth connectivity has become a must-have feature for seamless audio streaming, hands-free calls, and overall convenience.

But what if your car has an older music system without built-in Bluetooth? Don’t worry — you don’t need to replace the entire stereo. You can easily convert your normal car music system into a Bluetooth-enabled one with just a few affordable gadgets. Let’s explore how to do it and the different methods available.

1. How to Convert Car Music System to Bluetooth?

If your car doesn’t have Bluetooth, the simplest and most cost-effective solution is to use a Bluetooth receiver or adapter.

A Bluetooth receiver connects to your car’s existing AUX input or USB port and pairs with your smartphone. Once connected, you can play music wirelessly, answer calls, and even use voice commands — all through your car’s speakers.

Here’s how to do it:

1. Buy a Bluetooth Receiver: Choose a good-quality receiver (like Portronics, Boat, or Ambrane) from trusted online stores such as SK Gadgets.
2. Plug into AUX or USB Port: Connect the receiver to the AUX port (if available) or use a USB-powered model.
3. Pair with Your Phone: Turn on Bluetooth on your smartphone and connect to the receiver.
4. Play Music Wirelessly: Once paired, enjoy wireless streaming directly through your car’s sound system.

It’s a quick and easy fix — no complicated wiring or installation required.

2. How Do I Make My Old Music System Bluetooth Enabled?

For older systems that don’t have an AUX port, you can still make them Bluetooth-enabled with FM transmitters.

An FM transmitter plugs into your car’s cigarette lighter socket and connects to your phone via Bluetooth. It then broadcasts your music to a specific FM frequency on your car’s radio.

Here’s how:

1. Plug the FM transmitter into the car’s charging port.
2. Pair it with your smartphone via Bluetooth.
3. Set a free FM frequency on both your transmitter and car stereo.
4. Enjoy wireless streaming and hands-free calling.

FM transmitters are an excellent option for older cars without AUX input. Many modern transmitters even include USB ports for phone charging and microSD card support for offline music playback.

3. How to Convert Non-Bluetooth Music System to Bluetooth?

There are three main ways to convert a non-Bluetooth music system to a Bluetooth-enabled one:

1. Bluetooth AUX Adapter: Perfect for cars with an AUX input.
2. Bluetooth FM Transmitter: Ideal for cars without AUX ports.
3. Bluetooth Cassette Adapter: If your car still has a cassette deck, you can use a Bluetooth cassette adapter that fits right into the slot and connects wirelessly to your phone.

Each of these methods is simple, affordable, and reversible — meaning you can easily remove the device whenever you want.

4. Can I Convert My Old Stereo to Bluetooth?

Absolutely! You don’t have to replace your old stereo system to get Bluetooth functionality.

If your stereo has RCA (red and white) input jacks, you can use a Bluetooth RCA receiver. These small devices plug directly into the audio input ports and connect to your phone wirelessly.

For home stereos, devices like the Portronics Auto 12 Bluetooth Receiver work perfectly — giving you wireless audio streaming on any legacy system.

So yes, even your old stereo can enjoy modern wireless convenience with a small Bluetooth adapter.

5. Can I Add Bluetooth to an Old Car Stereo?

Yes, adding Bluetooth to an old car stereo is easier than you think. Depending on your car’s setup, you can choose:

• AUX-based Bluetooth Adapter – If your stereo has a 3.5mm AUX input.
• FM Transmitter Bluetooth Adapter – If your stereo only supports FM.
• USB Bluetooth Dongle – If your system has a USB input (though this works only with certain models).

Once installed, you can make hands-free calls, play music from Spotify or YouTube, and even use your phone’s voice assistant — all through your existing speakers.

6. Can I Install Bluetooth in My Car?

If you’re looking for a more permanent and integrated solution, yes — you can install Bluetooth directly into your car through a professional audio shop.

Modern Bluetooth car kits can be hardwired into your vehicle’s audio system, giving you a factory-like experience. These kits often include features like:

• Steering wheel control integration
• Built-in microphone for clear calls
• Automatic pairing when you start the car

However, for most users, simple plug-and-play solutions like Bluetooth receivers and FM transmitters are more than enough. They’re affordable, quick to install, and offer great sound quality without needing technical expertise.

Converting your normal car music system to Bluetooth is one of the easiest upgrades you can make to improve your driving experience. Whether you choose a Bluetooth receiver, FM transmitter, or a permanent Bluetooth kit, you can enjoy wireless music, calls, and convenience within minutes.

You don’t need to spend thousands replacing your stereo — just pick the right adapter and give your old system a smart, modern touch.
