How to Fix Bluetooth Lag In Car – Things You Must Know

How often have you heard someone say something along these lines: “I don’t want to get into a fight over who has the better phone, I just want to talk to my friends without having to worry about Bluetooth lag.”

The issue is, Bluetooth lag is real, and it’s happening to a lot of us.
Bluetooth is a wireless communication standard that allows devices to connect wirelessly within short distances.

How to Fix Bluetooth Lag In Car – Things You Must Know

This means that you can send data from one device to another using Bluetooth.

In addition to connecting two phones or computers together, Bluetooth also enables other devices such as speakers, headsets, printers, cars, fitness trackers, smartwatches, and even refrigerators to communicate with each other.

Bluetooth is a great way to transfer files between devices, but it does come with some limitations.

If you’re experiencing Bluetooth lag, then you might want to check out our guide on how to fix Bluetooth lag in the car.
If you are not sure what Bluetooth lag really is, read on for an explanation!

What Is Bluetooth Lag?

The term Bluetooth lag refers to your inability to hear audio through your smartphone when paired with Bluetooth headphones.

The problem occurs because both the speaker and phone use Bluetooth technology for transmitting audio. However, they do this at different frequencies.

You can think of Bluetooth as a radio frequency (RF) band. When you transmit information over this band, there will be interference.

It’s like trying to listen to a song on AM radio while driving down the highway. There will be static noise, and you won’t understand any words spoken by the person next to you.

This is exactly what happens when you pair a smartphone and Bluetooth headset.

The phone uses its own RF band to transmit audio which gets mixed up with the Bluetooth signal coming from the headset.

The result is that the sound quality is reduced, and you end up hearing low-quality music.

This is why you need to make sure that you turn off Bluetooth on your phone before getting into your car. Otherwise, you will experience Bluetooth lag.

Why Does Bluetooth Lag Happen?

There are several reasons why Bluetooth lag could happen. One reason is that Bluetooth technology isn’t always ideal for transferring large amounts of data.

For example, if you were playing a game on your phone and wanted to share it with your friend, then Bluetooth would probably work fine.

But if you wanted to stream Netflix or play a video, then Bluetooth would definitely struggle.

Another possible reason is that your phone may be too far away from your car.

Even though Bluetooth works best when the distance between your phone and the transmitter is less than 10 meters, sometimes it still doesn’t work properly.

The main cause of Bluetooth lag, however, is a poor connection. If Bluetooth was working perfectly, you wouldn’t see any problems with the audio.

With poor connection, you’ll notice that you can only hear part of the conversation, and the rest of the time, you’ll just hear static.

What Causes Bluetooth Lag in Cars?

When you’re in a vehicle, Bluetooth connections tend to have more issues than those made outside the car.

A vehicle has many components all connected to one another and these components generate electromagnetic fields. These fields interfere with the Bluetooth signals.

When you start a conversation, Bluetooth becomes active and sends out a signal that tells other Bluetooth devices within range that they should connect.

This process takes place via a handshake where each device sends out a series of short pulses.

Once the handshake is complete, the two devices become “paired” and they remain connected until one of them disconnects.

However, when you enter a vehicle, the engine creates strong magnetic fields that affect the transmission of Bluetooth signals.

Because of this, you may not be able to hear anyone speaking to you through your Bluetooth headphones unless they move closer to you.

If you want to fix Bluetooth lag in cars, there are a few things you must do:

1. Turn Off Your Phone’s Bluetooth Connection Before Getting Into Your Vehicle

It’s important to note that turning off Bluetooth is different from simply switching to Airplane Mode.

When you switch over to Airplane Mode, you disable the cellular network so that no calls or texts can come through.

However, turning off Bluetooth allows your phone to communicate with your car but prevents it from communicating with other devices like your phone.
To turn off Bluetooth on your iPhone, open up the Control Center by swiping down from the top right corner of the screen. Then tap on Bluetooth and press the button next to it.

Tap Turn off Bluetooth On/Off and press the toggle button.

2. Make Sure That Your Phone Is Connected To The Transmitter

Make sure that your phone is paired with the transmitter before getting into your car. It might seem obvious, but some people forget to pair their phones with the transmitter.

You can make sure by looking at your smartphone’s Bluetooth settings. If it’s listed under that section, your phone is already paired, and you don’t need to do anything else.

3. Reset the Bluetooth Connection Between Your Device And The Transmitter

If you’ve tried everything above, and you’re still experiencing lag, try resetting the Bluetooth connection. Now, follow the instructions to connect to iTunes.

4. Check Your Audio Settings

If your audio sounds distorted, check your audio settings. Many times, lag occurs because of an issue with the audio quality.

5. Try Using Other Devices

Sometimes, the problem isn’t the Bluetooth receiver itself. Sometimes, the issue lies with how the driver is using the device.

If you have multiple people sharing the same device, everyone will experience lag at different times.

6. Clean Your Receiver

Another way to get rid of lag in a car is to clean your receiver. If you find that your receiver is dirty, wipe it down with alcohol.

Doing this will remove any dirt that could cause interference.

They also have built-in antennas that allow them to transmit better signal strength.

Frequently Asked Questions

In this section, we are going to answer some burning questions you might have concerning how you can fix Bluetooth lag in your car. So, without further ado, let us get started!

Can You Fix Bluetooth Lag?

Yes, you can. There are many things you can do to fix Bluetooth lag. But first, what exactly does Bluetooth lag mean?

Bluetooth is a wireless technology used to transfer information between two devices.

It works via radio waves rather than cables. This means there is no wire connecting your devices.

Instead, they send data back and forth via radio frequencies.

Bluetooth was developed by Ericsson and has been around since 1999. Since then, it has become popular across all industries and applications.

For example, Bluetooth is widely used in cars, smartphones, laptops, tablets, and even smartwatches.

Why is Your Bluetooth so Laggy?

There are many reasons why Bluetooth would be lagging including:

  • Network Latency
  • Data Loss
  • Radio Frequency Interference (RFI)
  • Battery Drain

It’s important to note that most drivers aren’t aware of the factors causing Bluetooth lag. They simply assume their Bluetooth is bad.

So, how do you know whether your Bluetooth is working properly?
To determine if your Bluetooth is working correctly, start by checking your smartphone’s settings.

If it’s not listed under that section, you don’t need to worry about fixing it.

However, if you see the name “Bluetooth” in your phone’s settings, but none of the options are enabled, then you should contact your phone provider regarding the matter.

How Can You Improve Your Bluetooth Connection?

If you find your connection is consistently dropping out, try one of the following methods to improve it:

1. Turn Off The Vehicle Air Conditioner

This may seem like an obvious solution, but sometimes, we forget to turn off our air conditioning before getting into the vehicle.

After turning on the engine, however, you can disconnect the power cord from the battery until the engine cools down.

2. Use A Different Antenna

Most people think that when using Bluetooth, you just plug the antenna directly into the device.

While this is true for most cases, it doesn‘t always work well with certain models.

To make sure you’re getting the best possible reception, you should change your antenna.

3. Use An External Antenna

Since there are many types of antennas available, it’s impossible to tell which one is right for you.

However, if you want to improve your connectivity, you should consider buying an external antenna.

4. Turn On The Headphones And Keep Driving

If you feel like you’re constantly losing connection while driving, you can try listening to music through headphones instead of the speakers. That way, you won’t have to deal with any interference.

5. Change Your Phone’s Settings

Although it’s recommended using a headset, some users prefer to keep the speakerphone on.

Regardless of the type, though, changing your phone’s settings could help solve the issue.


Bluetooth’s technology has been around for quite some time now. And while it does provide many advantages, it can sometimes fail us.

This is especially true in automobiles where wireless connections are used more often than anywhere else.

However, there are ways to fix Bluetooth lag in a car. Just keep in mind that not all solutions are effective.

Some fixes only delay the process until the next time you go to drive. So, when fixing your Bluetooth lag, be patient.
