The answer is simple. It’s a brand. But not just any brand. This particular company was established by forward-thinking engineers for the sole purpose of creating innovative and modern OBD scan tools for personal use.

Their apps are specifically designed to be customized. Some coding is allowed so that the adapters can also perform functions that are not intended by the company but preferred by their customers. When it comes to quality, the company strives for the best by manufacturing its own chips instead of using cheap copies.

With the use of cutting-edge technologies, they’ve been able to manufacture tools capable of producing live diagnostics of the individual ingredients within a vehicle. These tools can also help with certain programming aspects of the vehicle, such as engine noise, led headlights, and speedometer.

The company’s expertise with OBD systems has led to creating great scan tools such as OBDLink LX, MX+, and CX.

OBDLink CX Bluetooth BLE OBD2 Adapter
OBDLink CX provides a highly sophisticated platform for diagnosing BMW and Mini vehicles.

OBDLink CX is a new OBDLink system that was specially created for BimmerCode to be used with BMW, Mini cars, and Toyota. This system covers all of BimmerCode vehicles, and as a result, is endorsed by the BimmerCode team.

The App for this machine works on both iOs and Android. It is optimized to ensure that it cannot be hacked, and it also gives an uninterrupted network connection.

Another great thing about this system is that you can easily customize things like engine settings and mirror positions with the App. You can also check your vehicles’ live diagnostics to determine if everything is in great working order.

With the addition of an overvoltage protection system in the machine, OBDLink CX is safe to leave plugged in for a long period. The connection between the system and the App is through Bluetooth, and the system allows coding with the use of third-party apps to configure your vehicle. The tool also allows some expert functions.

OBDLink MX+ OBD2 Bluetooth Scanner
The OBDLink MX+ is very compatible with a lot of vehicles especially when it comes to GM and Ford cars.

This App also handles the diagnostics of your vehicle. If there’s something wrong with your car, it handles that. Part of the thing the App helps with is logging through data reading. It has a dashboard that displays the gauges, the engine temperature, the mile per hour and other things that a comprehensive dashboard has.

The great thing about OBDLink MX+ is that its diagnosis is accurate, and it can save you the stress of having to go to the repair shop to get a diagnosis for your vehicle. It can also save you money if what is wrong with your car is a minor issue.

Since both of the devices perform mainly the same functions, they have numerous similarities. Among the things, OBDLink CX and OBDLink MX+ have in common is the ability to operate them from an android and iOS device. This connection is usually maintained with the use of Bluetooth, and the line is secure without the slightest possibility of it being hacked by an external party.

Another thing they have in common is that their overvoltage protection capabilities are roughly the same. This means they have inbuilt systems that allow them to regulate currents up to 100V. Like most OBDLink products, the warranty and the money-back guarantee is also the same at 3 years and 90 days, respectively.

OBDLink CX and OBDLink MX+ can be plugged into your vehicle with the use of an OBD2 port for the sole purpose of retrieving data and giving you access to some features that may not originally come with it.

These are not the only similarities between the two. They also have really low power consumption, which makes them great for the life of your vehicle.

The last similarity between the two is that they both have the free OBDLink App, which you automatically get on buying any of the scanners. This App is free, and it helps with diagnostics and live data reading. When your vehicle is in motion, the App will give you accurate data which you can use for logging.


When it comes to design, OBDLink CX is smaller than OBDLink MX+. It is only a little less than one inch long, and it weighs a total of 20 grams, while MX+ weighs a total of 85.1 grams. With less than one inch from the port, it has the benefit of looking like a part of the vehicle instead of an intrusive part of it.

Even though the OBDLink MX+ is not that big, it is definitely bigger than the CX. Because of that, it has more processing power, operates on more platforms, has more ways of establishing the connection, has a higher operating voltage, and better specs. It can even be used with more than 3 times the number of vehicles the OBDLink CX can be used with.


Although both devices can be used for BMW and Mini cars, the specifications are very different. For example, while the OBDLink CX works for only BimmerCode Vehicles, the OBDLink MX+ covers a wider range of vehicles from those made in 1996 till date. If you have a lot of vehicles, this is certainly a better option than the CX.

Features and Functions

OBDLink CX is specially created for BimmerCode to be used in conjunction with BimmerLink for specific vehicles like BMW and Mini vehicles. The connection is maintained through Bluetooth, and it can be used on only two operating systems, iOS and Android.

The main function of the device is to check engine diagnostics, but it also performs some additional functions like automatically adjusting the side mirrors. For the purpose of adding extra functions that are not included in the free OBDLink App, which comes with the tool on the purchase, extra coding is allowed.

OBDLink MX+, on the other hand, does not have a streamlined functionality. Rather than a specific type of vehicle, the tool can perform engine diagnostics for multiple systems. It allows you to select your vehicle and access a functionality based on its model and make.

Bluetooth Connectivity

When it comes to connecting with an operating system, both tools use Bluetooth. OBDLink CX uses Bluetooth 5.1 BLE, to be exact. This model of Bluetooth uses an advanced location discovery system, which creates an impeccable accuracy in connections. Initiating connection is also faster and easier than with the other versions of OBDlink.

On the other hand, OBDLink MX+ uses version 3.0 Bluetooth, which also has a fast connection, but not as fast as the Bluetooth model 5.1. This Bluetooth model requires the user to push a connect button before the connection can be activated. So, people can’t just join an open channel willy-nilly.

For the protection and to prevent hackers from getting to your vehicle through the OBD Scanner, the Bluetooth of the device has secure 128-bit data encryption.

Supported Protocols

This is where the biggest difference is between OBDLink MX+ and OBDLink CX. While OBDLink MX+ supports a very broad range of protocols, from those popularly used in the United States to those used worldwide, OBDLink CX supports only famous people in the United States.

The protocols that are supported by OBDLink MX+ are OBD2, JOBD, GM-LAN, Ford MS-CAN and EOBD, while those that OBDLink CX supports are mostly limited to OBD2 variations like KWP2000, ISO9141, SAEJ1939 and ISO15765.


OBDLink CX is compatible with vehicles that have OBD diagnostics incorporated in them. But, it is more suitable for Mini vehicles and BMWs because of the ability to use it in conjunction with BimmerCode to carry out advanced coding, giving access to certain features and functions on these vehicles.

OBDLink MX+,on the other hand, is compatible with all vehicles that use OBD2 diagnostics. It has different systems which it gives you access to based on the make and build of your vehicle.

However, these are just basic settings. For the advanced settings and diagnostics, the device only works for Ford, GM, Mazda, Nissan, and Toyota.

Battery Saving Mode

Both devices have an in-built battery saver mode even though they vary. This technology is a signature OBDLink solution called BatterySaverTM Technology. It ensures that once you have plugged your scanner into your vehicle, it does not draw too much power from your car battery and drain it.

The moment you switch off your engine, the devices automatically go off too, and the moment you power it on, they start collecting engine diagnostics immediately.


The two devices have the same warranty, which has set OBDLink Scanners apart from other scanners. The warranty is great for three years after purchase, and there is an unconditional money-back guarantee for products within 90 days of purchase.

App and Software Updates

The OBDLink CX and MX+ have a free OBDLink app that allows you to access the diagnostics and basic settings of your vehicles. This App works well on android and iOS devices. Installing is almost automatic. The package is within Bluetooth, and all you need to do is to follow a short process.

For OBDLink MX+, an app called OBDWiz is going to be available to install on your Window OS. This App performs all the functions of an OBDLink App with the addition of a little improvement.

The interface is somewhat better, and many people love that. If you’re one of those who prefer the interface from this App, you can easily access your vehicle’s diagnostics and settings through your PC.

One important thing to note is that it is not compulsory to use these devices with the primary apps that come with them. The setup of the devices makes it easy for the users to access third-party apps for either coding or better settings.

Compared to OBDLink CX, MX+ is a great tool for the FORScan Team

For example, one popular App many users eventually make use of is FORScan. Other third-party diagnostic apps that can be used are Carista, Torque, AlfaOBD, OBD Auto Doctor, and DashCommand. OBDLink CX is designed for BimmerCode and Bimmerlink. So, it especially works with those apps.

Like FORScan, the BlueDriver app is also a great app to use in conjunction with any of the two devices because it allows the user to have access to a large number of functions, especially when it comes to the engines. Some of the engine functions they support are brake system, TPMS, SRS, and so on.

Updating the App that comes with the devices is free.

At this point, it’s obvious that both of the devices are great but for different purposes. While the OBDLink CX has a more streamlined function, the MX+ has a broad one. That is why we think OBDLink MX+ is the best choice.

Not only does it function perfectly well with more vehicles, it supports MSLAN and GMLAN protocols which makes it extremely suitable for GM vehicles and Ford vehicles. Because of its very powerful processor, it can also read data from several vehicles as long as they were made after 1996.

OBDLink CX, on the other hand, is best if you are using a BMW or a Mini vehicle. The device was created for BimmerCode which handles the settings of these cars and using it will give you access to more configurations on your vehicle. You can even include codes for things that did not originally come with the vehicle.

So, we recommend this particular device for BMW and Mini users. The connection is also secure because it makes use of the Bluetooth 5.0 BLE and it is immune to hacking. So, there’s no chance of an external body taking control of your vehicle without you accepting it.

Bottom Line

The OBDLink MX+ is very compatible with a lot of vehicles especially when it comes to GM and Ford cars. It also supports a lot of OBD2 protocols on vehicles made outside the United States.

Still, it has nothing on the capacity of OBDLink CX which provides a highly sophisticated platform for diagnosing BMW and Mini vehicles.

In all, these two are great for car owners who want to be able to quickly tell what’s wrong with their vehicles at any given time.


Using the OBDLink MX+ is very simple. All you need to do is to plug the device into the OBD port in your vehicle. Once that’s done, click the Bluetooth discovery button, and pair it with your device. Once that’s done, you should be able to access the apps that come with it.

Launch the OBDLink software, click connect on the software. Follow the instructions, input your car model and manufacturer and start using the system settings that come with it. You can also access the diagnostics of your vehicle from this App.

2. Can you drive with OBD plugged in?

The only time you can get diagnostics from your device is when it is plugged in. That is why the two devices have in-built battery saver modes, which prevent them from drawing too much power from the car battery. So, the answer is yes; you can drive with OBD plugged in.

3. How do you tell if OBD codes have been cleared?

There is no particular way to tell that the error code has been cleared except in the diagnostics on the App. Once the error code has been resolved, the App will tell you so.

OBDLink has the best scanners for OBD2. The devices manufactured by the company can work on many operating systems, and they can also read data from a wide array of vehicles. There are simple enough to pick from for your preference whether you want to use them for personal or professional purposes.

On your App, go to settings and under that, click on Firmware Updates after which you should check for updates. If there is an update, download and install it. To update on your PC, the right process is to download, extract the archive and run it.
