Item# 426101


OBDLink® MX is a budget-priced, pocket-size Bluetooth OBD-II adapter for all OBD-II compliant vehicles (except hybrid or electric vehicles). It can be used as a diagnostic scan tool, trip computer, logger, and real-time performance monitor. OBDLink® MX surpassed performance in every competing Bluetooth OBD-II adapter, delivering 300% more data samples per second. Its BatterySaver™ sleep mode allows the adapter to stay plugged in continually, without draining the vehicle’s battery.

Unlike the vast majority of Bluetooth OBD adapters, which constantly broadcast their presence and use an easy-to-guess 4-digit PIN, OBDLink® MX utilizes a unique multi-layered link security mechanism, eliminating the risk of unauthorized access. OBDLink MX’s support of the de facto standard ELM327 command set, makes it compatible with tons of third-party OBD software and mobile apps.

OBDwiz and OBDLink app, included with OBDLink® MX, allow you to:

  • Turn off the check engine light, and erase stored diagnostic information
  • Read and erase stored, pending, and permanent trouble codes (both generic and manufacturer-specific)
  • Access freeze frame information
  • Display, graph, and log 90+ real-time parameters
  • Create custom digital dashboards
  • Measure and display fuel economy
  • And much more!


  • Maximum vehicle coverage (Verify your vehicle is OBD-II compliant)
  • Supports SW-CAN & MS-CAN protocols
  • World’s fastest Bluetooth OBD-II adapter

Great scan tool!Review by Chris C. [Amazon Review]
Now that Windows 10 works on bluetooth, this is a useful device for diagnosing common auto problems with respect to the check engine light (CEL), as well as displaying what the computer is reporting on your car. I've used this to help trace down an emission issue (broken purge valve), as well as playing with the app for seeing engine load, intake CFM, etc. (android app allowed heads-up display mode)

Would definitely recommend. (Posted on 12/1/2016)
Self-Mechanic's dreamReview by Sergio Ruelas [Amazon Review]
I've had this scanner for about 2 years now. It's on the way more expensive side versus other cheap ebay scanners, but it's worth it. Considering security, this device has measures to protect itself from being hacked. It communicates much faster with my phone than the other scanners, and I have never had any problems connecting with it. I love the software that comes with it for windows, there's so much you can do. Gone are the days of you not being able to diagnose your own car. (Posted on 12/1/2016)
Good fast connection and paired up first tryReview by PrimeShopper [Amazon Review]
Good fast connection and paired up first try. I use this with Torque on a tablet on the dash all the time. Will see how this one does with fast logging and displaying gauges. This replaced a cheap adapter that Torque would report as faulty some of the time. (Posted on 12/1/2016)

This is absolutely, without-a-doubt the FASTEST OBDII adapter I've ever used. I've even used hard-wired OBDII adapters that were not nearly as fast as this one. (Posted on 11/16/2016)
Yes.Review by Sbell [Amazon Review]
This OBD reader is friggin awesome. I love that I can keep it plugged into my truck without worrying that it will slowly drain the battery. Don't worry about someone else being able to connect to this, the only way you can set it to accept other phones is by physically pressing a button on the reader; it is also only a short-range transmitter. Having the ability to simply connect to the device from my phone an monitor many different aspects of the engine while its running is very handy. Definitely recommend buying this.

Great for pulling Ford and GM Specific CodesReview by Sam24and48 [Amazon Review]
I ordered this after having some issues with our Parking Aid system. I have not used the included obdlink app but did use the Forscan app designed for Ford, Lincoln, Mercury, and Mazda vehicles. It relayed the correct error code without any problem and helped me identify the exact part that I needed to replace. I had one of the chinese elm27 obd scanners and it had no ability to pull any GM or Ford specific bus codes and at this point I consider it worthless. Very happy I purchased the MX and am sure it will come in handy in the future as my family has all GM and Ford vehicles. (Posted on 11/16/2016)
The app works great with both my 13 Subaru and 13 FordReview by HillBilly [Amazon Review]
Dealership can bugger off now that I can diagnose my own issues first time used already paid for itself. The app works great with both my 13 Subaru and 13 Ford. (Posted on 11/16/2016)
See what is going on in your carReview by Grimmace [Amazon Review]
Does what it says. Replaced an older unit with this. It is really compact and and be stored anywhere in the vehicle or on the OBD port without getting in the way of anything. Phone connected to the app quickly and showed all the data. Downloaded the PC version and was able to connect without issues either. Anything that prevents $100+ just to see what the problem is worth it. It pays for itself before you know it. Good product. (Posted on 11/16/2016)

works great. worked on my Pontiac G8 GT and Works on my 2015 Mustang GT. this basically will work on any car using a OBD II connector. this also is one of the better OBD II connector. they are not all created equally. (Posted on 11/16/2016)
A must. Best for home and mid range usage. Almost a profesional tool. Great quality, great free software.Review by DefToneR [Amazon Review]
I have 4 adapters, 1 its small handheld, 3 are BT chinese, including the Elm327. With some cars I did not have any problem until I bought my Jeep.
Non of my adapters work on my Jeep Grand Cherokee 1999. I was starting to think that the port or the ECU was damage, but I realice that non of my adapters was more expensive than 20U$ So I decided to bought a good one and give it a try. I Have torque (the android app) and from their wiki I found that one of the most recommended was this "ScanTool" So I went for it.

This one read the Jeep with no problem. Is super fast accurate data. The ELM327 take time to connect to BT... the data have some lag. Some times it disconnects. and will not work with this special protocol for ford/gm (and jeep). The prices is like 4x. But If you take 5 minutes and think about it.... you are contacting and writing your car's computer (Power Train/ECU)... so. some bad chip or soldering could take 12v to the com port. and severe dame to the ECU.... making your car useless...

A good ODB scan toolReview by Larry Sunderland [Amazon Review]
I have found this to be helpful in knowing why the check engine light is on before taking a car in for service and repairs. There is a also the option to monitor real time engine performance via my cell phone or other Bluetooth device. As long as you don't allow it to distract you from the actual task of driving, the additional info can help you better tailor your driving habits. (Posted on 11/16/2016)
This is ONE you need for a Windows 10 laptop scanner. 5+!Review by Anonymous [Amazon Review]
First I tried an Autel direct connect: Very solid, lots of features, but the software froze up the second time I used it: bye!

Then I got a Veepeak wifi scanner for Windows. It was a very tight fit (too tight), hard to connect, and then all I got with my expensive OBD Auto Doctor software was "Invalid OBD Standard"....bye.

Then I bought this. First I tried it with OBD Auto Doctor and it paired and worked just fine. !!!!

The I downloaded their OBD MX software from their site, ****SAVE THE LITTLE PIECE OF PAPER WITH THE LICENSE CODE*** that comes with the scanner. The scanner paired to my Windows 10 laptop fine, but the program itself would not connect via Bluetooth UNTIL I changed the COMMUNICATION TYPE setting to the first checkbox for USB,BluetoothRS-232 AND also changed to COM PORT 6, and then everything clicked right in.

Frankly, the OBD WIZ app was as good as the expensive OBD Auto Doctor in my opinion, for everyday drivers. I am sure there are differences that mechanics would notice and so on, but I don't understand half the stuff they scan anyway.

In short, this scanner and their FREE software is all you need for a very nice Windows 10 laptop auto code scanner. And yes it does clear Check Engine Lights -CEL- codes. Also, the dashboard gauges are quite nice. (Posted on 10/20/2016)
Works as intendedReview by Zach [Amazon Review]
I have had no issues with the device and it has already been put to work in a handful of different vehicles. The communication speed between the device and phone is blazing fast. If you use an application like Torque Pro the device will read realtime data and display it with more accuracy than the actual gauges in real time.

This device is only as good as the software that supports it. It does come with free software that works well, and other apps are available on the marketplace that may work better with your particular vehicle (Forscan is an example).

The only reason I rated 4 stars instead of 5 is that you have to forget the device every time you disconnect from it. It gives a new code when you hit the bluetooth connection button so it won't 'remember' your phone. This is a minor inconvenience but it is still an inconvenience. Perhaps ScanTool can introduce a watch battery powered memory much like how your computer remembers Bios settings when it is turned off?

Hope the review helps, I am pleased with my purchase. (Posted on 8/15/2016)
Great tool for the novice or the pro.Review by G. Thomas [Amazon Review}
I am a professional auto technician with access to several high end scan tools. I got this tool to use as a quick preliminary check tool before breaking out the slow to boot and cumbersome "big gun" tools but I find myself using this tool instead of the high end tools because of it's speed and coverage. Great tool!!!! (Posted on 8/15/2016)
GREAT, GREAT, GREATReview by Jeremiah Mauricio [Amazon Review]
I bought this with some reservations, as my wife's 2002 Subaru Forester doesn't function on some inexpensive OBD II readers. The readers don't see the car, and I don't know why some do and some don't. However this works perfect, I keep it in the car and use the software to play with the digital dash. I can read and clear codes, and leave it plugged into whatever I'm driving just to have it with me. Friends have borrowed it and it is awesome.

I also race and use other apps with this and it works perfect! This might be one of the best tools I have bought in the last 5 years. (Posted on 8/15/2016)
Top Shelf OBD-II Bluetooth ToolReview by Carlos Thomas [Amazon Review]
I've tried a few of the cheaper items before finally settling on this. The OBDLink tools are known for being good - I actually also own the SX. I wanted something to use with my phone for checking stuff on my vehicle, but the cheaper items were slow or gave issues with the electronics in the vehicle. Since I've used this there have been no problems whatsoever.

My advice would be to use this along with another tool such as Torque. While the original software gives EXCELLENT reports, third party applications seem to work faster with the dashboard items. Other than that one hiccup the tool is just that: EXCELLENT. (Posted on 8/15/2016)
Worth every pennyReview by John M. [Amazon Review]
Indispensable tool for the DIYer! Paired with a paid app that includes an engine temp alarm has saved my p38 from catastrophic overheating while working out cooling system bugs. Possible app related, but maybe 1/20 will not connect via bluetooth to my tf101 tablet and I must take the extra few minutes to resync. Worked well on 3 vehicles so far (2002 Range Rover, 2000 Jeep Wrangler, 1998 Hyundai Elantra.) (Posted on 8/15/2016)
OBDLink wins.Review by M. Cole [Amazon Review]
I had difficulty deciding between the Bluedriver, and the OBDLink. After testing both, I hope the review below may help you.

The ability to use iOS is nice, however, the OBDLink coupled with a $63 Android phablet worked better in my situation, as described below.

The layout of the included OBDLink software is excellent. I can easily see many live parameters on one screen, without jumping through hoops and dozens of clicks to display them.

With the Bluedriver, I was disappointed with the layout of the real time live data screen. It is nice to have the option to show the graphs on the main page along with the data, however, it was laid out in a semi-confusing manner, hard to tell at a glance which line the data referred to, with no obvious visual breaks between lines. As a mechanic, I prefer the capability to show many items at once on the page, with the field description at the left, and the data on the right. When the graphs always included, it really limits how many fields can be displayed at once. Some of the parameter descriptions were vague, and hard to identify when on the data viewing screen, although they were clearly labeled on the parameter selection screen. It was especially hard to identify which O2 data I was looking at, and which sensor it was for.

Being limited to the Bluedriver software was a large reason I selected the OBDLink device. I like the functionality and layout of the ODBLink software, and open compatibility nature of their setup. There are some custom written programs that work with ELM 327 that really do much more than either OBDLink or Bluedriver by themselves, and the ability to utilize those programs, like Forscan, was huge for me. I can get access to seemingly every parameter on my 2012 F350 with the OBDLink and Forscan. Really a dizzying array of data.

Since I am not set on using iOS, this OBDLink was a great solution.

One thing that would make these devices even better would be bi-directional control. (Posted on 8/15/2016)
Saved me a trip to the dealer!Review by Tom Aiken [Amazon Review]
I use this with a nexus 7 tablet for monitoring my 6.4 Powerstroke with torque pro mostly, but I was able to use the forscan app as well to diagnose an ABS light on my dash, saving myself a costly trip to the dealer. I also love that I can use it on my girlfriend's Cadillac STS as well which is a big plus because maintenance on it is just as expensive as my diesel! As always prime two day shipping was great.

Works great with LinuxReview by Abu Ari al Saba [Amazon Review]
It worked great with my 2003 Honda Accord and Odyssey and my 2001 Corvette. I am running Ubuntu 14.04 LTS Linux on a Asus laptop with Plugable Bluetooth adapter. Because I run Linux, I used OBD Auto Doctor. OBD Vehicle Diagnostic scanner is available for free on Ubuntu Software Center but I wasn't able to get it to work with Bluetooth. There are plenty of instructions on the web on how to adapt it to Bluetooth but it didn't work. Free wasn't worth the hassle. OBD Auto Doctor, at $50.00 for the mid-tier version, worked immediately with the Scan Tool. Bottom line: if you are using Linux, this hardware works great, as long as you can get Linux software that works; OBD Auto Doctor works great with Linux. The only reason that I didn't give it the fifth star is that it would have been even better had it been even lower profile. (Posted on 8/15/2016)
