If you want to buy an OBD-II Bluetooth device you should know what you shook look after in one. Read the following buying guide to find out all there is to know about scanning tools and read our OBD2 Bluetooth reviews to find the right fit for you.

The Top Things to Consider When Buying an OBD2 Bluetooth Adapter

You can use the OBD-II for extra performance. Even though most OBD-II systems are sealed and won’t allow any kind of chip replacement, they provide valuable real-time data very useful for tuners. Some power loaders will actually be able to reprogram the parameters of the OBD-II system to increase the performance options. The only thing you should keep in mind is that your car must be able to pass the emission standards after the tuning.


Not only does the scan tool be compatible with your car model, but it also has to be compatible with your device, as well. All the scanning tools will work with most car models manufactured after 1996, so chances are your vehicle will be among them. But not all devices are compatible with all the operating systems.

  1. Android Operating System
    android-for-obd2-bluetoothMost scanning devices are compatible with the Android Operating System. Some of them are developed with specific Android apps you have to use to get the right reading, while others can be used with third-party apps. If you get a model that has a specific app, you’ll be able to use it for free, since it’s price is included in the cost of the device. If it uses a third party app, you will be able to download one from Google Play Store. The price for these apps varies greatly, so you’ll be able to download some for free, while others might cost over 50$. This price is usually set by the performance. Some apps will be able to show you only a part of the car functions, while others will show all of them. The best Android-based apps will be able to make easy to follow graphics on all the functions.
  2. Windows Operating System
    Windows-for-obd2-bluetoothNot many manufacturers decide to make their devices compatible with Windows-based devices. A small fraction of these manufacturers will make the tool work on the mobile version of Windows, though, so you need to check before buying one if you intend to use it with a mobile device. The software needed to make the tool compatible with your device can be downloaded for free or for a small fee.
  3. IOS
    ios-for-obd2-bluetoothThis might come as a surprise, but IOS, the operating system used by Apple on all their devices, including their laptops is the least compatible with scanning tools. The reason behind it is the fact that it’s more difficult and more expensive to develop IOS compatible devices and apps. Even though this is the case, you can still find enough models which will be compatible with your devices. The apps you need to run can be found on iTunes, usually free or for a small fee.obd2-bluetooth-adapter-operating-systems

Device Price

The ObD2 scan tools market is a very large one. Similar to the other markets, you will find all sorts of models that come at different prices. They might seem to do the same thing, but that’s not necessarily true. Just like any other product, you might think that the more expensive products will be able to perform better than the cheaper ones, but that might not necessarily be true.

  1. Cheap Models
    Cheap models will most likely be able to connect to a singular operating system, so that might be a problem if you intend to change your reading device in the future. After connecting and installing them you will be able to use them through third-party apps. They will be able to read and clear all the basic codes, and some of them might even be able to read the manufacturer specific codes. One of the problems you might encounter with cheap models is that they can consume a lot of power, so leaving them plugged might damage your battery.
  2. Medium-priced Models
    Most medium-priced models will most likely connect to two operating systems. After connecting and installing them, you will be able to control them through a third party app which might cost you, but some of them will be delivered alongside a specific app. They will be able to read basic and specific codes, and some of them might even read and clear enhanced codes, such as ABS, Transmission, and Airbags. You can leave most of them connected at all times, they will not damage your battery.
  3. Expensive Models
    Expensive models are compatible with all the operating systems. This might not be an advantage for most people since the regular user doesn’t usually have devices with more than two different operating systems. After connecting and installing them you will be able to control them through a specific app, which will provide increased an increased accuracy for the reading. Even though the specific apps are really accurate, some third-party apps are superior. They allow you to check more functions and develop easy to read graphics. Most models are able to read and clear enhanced codes and provide valuable data. You can leave all of them plugged in and they won’t damage your battery.

Specific or Third-Party Apps

obd2-bluetooth-appsEven though the scan tool is the working device, the app is responsible for the interpretation of the data. Without the app, you couldn’t see the results. Many manufacturers don’t bother with developing a specific app for their device, but some do. Which is the better one?

  1. Specific Apps
    Specific Apps are specially designed to work with a single tool. This makes the app’s accuracy extremely high. It will generally pick up data third-party apps will most likely miss or exclude from their reports. But a developer that specializes in scanning tools production might not be the best company to develop software as well. That’s why some of the specific apps are accurate but don’t have as many features as the third party ones.
  2. Third-party Apps
    Third-party apps are developed to be compatible with many scan tools. They will install rather quickly and make pretty accurate readings. The readings they make on the same vehicle will be different if they are used with different devices, but still accurate enough for you to find out the car’s problems.

Free or Paid Apps

Choosing which app to use is always difficult, even though there are some renowned companies on the market. You should choose the right app for your device, no matter the cost.

  1. Free Apps
    Free Apps will allow you to interpret the basic readings. Some will even allow you to read and clear your “Check Engine” light. But why would you decide to use this kind of app if you purchased a device that’s able to read and clear enhanced codes? It will only stop it from doing its job properly.
  2. Paid Apps
    There are many types of paid apps. Some cost 5$, while others cost over 50$. The price difference is determined by their features. The 5$ app might allow your device to read and clear basic and manufacturer specific codes, but the 50$ one will definitely allow you to read all the enhanced codes, as well. You should check out the apps that are able to do the same things as your device. There’s no point in spending extra money on features you won’t use, but there’s no point in saving some money from the app, but not allowing your device to function properly, either.


obd2-bluetooth-warrantyIf you have the possibility of purchasing a model with warranty over one without at a similar price, don’t waste your time thinking too much about it, just get the one that comes with one. We’ll explain why this is important.

  1. Limited Warranty
    Many producers offer a limited warranty for their product. The duration of it might be different from one producer to another, but it’s better to have one. These Bluetooth scanners are usually very durable, so you’ll be able to use them for a long time. If, however, a model is defective, you should be able to change it.
  2. Lifetime Warranty
    If you have the possibility to buy a model that comes with a lifetime warranty, do it. Keep in mind that these devices are diagnostic tools you should be able to use for a long time. If you have a garage or a used car dealership, these devices will prove invaluable, so you should have the possibility to get them repaired at all times.

Frequently Asked Questions – OBD2 Bluetooth Adapter

What Is The OBD2 Port And What Is It Used For?

OBD-II is the second set of standards and practices of the On-Board Diagnostic System. This system was first developed in the USA to make sure all the cars passed the emission standards and requirements for the maintenance of cars for extended periods of time. To make sure every manufacturer followed these practices, the law demanded that sensors should measure engine performance and the pollution level. At first, every manufacturer designed their own systems and signals, but soon there was a standard they needed to follow. OBD-II is the latest set of standards developed and implemented in 1996.

Why You Should Own an OBD2 Bluetooth Adapter

This set of standards is used to make sure the car manufacturers build vehicles which meet the increasing emission standards. OBD-II serves as a universal diagnosis and inspection method to make sure the vehicle is performing according to those standards.

Does My Car Have OBD-II?

If your car is built after the 1st of January 1996, it should have the OBD-II standard system. Manufacturers first started to incorporate the system since 1994, but some of the early models were not 100% compliant.

There are several protocols in use at the moment but the scan tools are able to read all of them.

How do we measure OBD-II output?

All OBD-II cars have an easily accessible connector. You should be able to access it from the driver’s seat. Look under the dash or near the ashtray.

What good does it do to measure OBD-II output?

If the “Check Engine Light” is turned on, or the car has some driveability problems, the OBD-II signals should be able to provide enough data to pinpoint the component that isn’t working properly, allowing you to save both time and money. Scanning these signals can offer valuable information when you intend to purchase a used car.

OBD-II and Your Car’s Health

Not so long ago, buying an OBD-II scanning device was not cheap. The high prices restricted home mechanics and small car shops from working with one, so the shops that could afford one charged a fee for reading the signals. With the new, more economical scanning devices are easy for anyone to access and interpret OBD-II signals, so you can make your own repairs.
