OBDLink MX+ Review: Is This OBD2 Scanner Worth It?
The OBDLink MX+ is not a bargain-bin Bluetooth code reader. It is a compact OBD-II adapter aimed at owners who want fast live data, broad app support, and deeper access than a basic check-engine-light scanner can provide. Its strongest case is flexibility: it works with iOS, Android, and Windows, supports Ford MS-CAN and GM SW-CAN networks, and can pair with specialized apps instead of locking you into one software ecosystem. That versatility comes at a premium price, so the real question is whether you will use the extra capability.

First Impressions
The MX+ feels purpose-built rather than generic. It is small enough to leave in many under-dash ports without becoming a knee hazard, and pairing requires pressing the physical Connect button, which is a useful security measure compared with adapters that constantly advertise themselves. OBDLink says typical installation takes only a few minutes, and buyer feedback consistently praises quick pairing and stable connections.
It is also important to understand what this device is. The MX+ is an interface between the vehicle and your software, not a self-contained handheld scanner. If you are still deciding what level of tool you need, this OBD2 scanner vs. code reader guide explains why an app-based adapter offers different strengths from a simple plug-in reader.
Performance and Feel
Live-data speed is where the MX+ separates itself from many inexpensive ELM327-style adapters. OBDLink advertises sampling rates up to 100 samples per second under its test conditions, which matters when graphing fast-changing values or displaying several gauges at once. The company’s own comparison testing reported materially faster PID refresh than BlueDriver. That is manufacturer testing rather than an independent lab result, but the hardware’s reputation for responsive live data is also reflected in user feedback.
For users who watch transmission temperature, fuel trims, oxygen-sensor behavior, boost, or multiple manufacturer PIDs while driving, that refresh headroom is more useful than it sounds: slower adapters can make multi-gauge dashboards feel delayed. The MX+ is therefore better suited to continuous monitoring and logging than readers intended only for occasional fault-code checks.
In practical use, the experience depends on the app. The included OBDLink app handles code reading, clearing, dashboards, logging, readiness information, and supported OEM data. Windows users also receive OBDwiz. More advanced tasks may require a third-party app matched to the vehicle, so buyers should check both adapter and software compatibility before assuming a particular function is available.
App Compatibility and Enhanced Diagnostics
This is the MX+’s most important secondary performance dimension. OBDLink lists support for apps including FORScan Lite, Torque, OBD Fusion, Car Scanner, BimmerCode, Carista, OBD JScan, AlfaOBD, Hybrid Assistant, and others. That makes the same adapter useful for very different jobs, from Ford-specific diagnostics to custom dashboards or hybrid monitoring. For a broader look at software choices, see these OBD2 app alternatives to Carly.
The built-in support for Ford MS-CAN and GM SW-CAN is especially significant because those networks can expose manufacturer-specific modules and parameters that ordinary generic OBD-II access misses. However, enhanced coverage still varies by year, make, model, module, and app. iPhone and Android owners should also review Android vs. iPhone OBD2 app compatibility before choosing their software stack.
Durability and Leave-In Protection
The MX+ has unusually detailed electrical-protection specifications for a consumer adapter. OBDLink rates it for 8–18V operation, up to 100V overvoltage protection, and temperatures from -4°F to 131°F. Its BatterySaver mode drops consumption to roughly 2 mA, allowing the device to sleep and wake automatically instead of remaining fully active after the ignition is off.
That design is reassuring for owners who want a permanent dashboard or logging setup. Still, any accessory creates some parasitic draw, so vehicles stored for long periods deserve normal battery-maintenance caution. The three-year warranty is also longer than what many low-cost dongles provide.
Value for Money
At OBDLink’s current direct price of $139.95, the MX+ is firmly premium. It is poor value if you only want to read an occasional P-code and clear a check-engine light; a much cheaper adapter can do that. Its value improves when you need iPhone support, Windows access, fast logging, free MX+ OEM add-ons, Ford/GM network access, or compatibility with several specialized apps. There is no mandatory OBDLink subscription, although some third-party apps and their advanced functions can cost extra.
Comparison to Similar Competing Products
| Model | Where It Differs |
|---|---|
| BlueDriver Pro | More guided, closed-app experience with built-in repair reports; MX+ offers broader third-party app support, Windows compatibility, and Ford/GM proprietary network access. |
| Veepeak OBDCheck BLE+ Plus | Far cheaper and supports iOS/Android plus many apps, but Veepeak states it does not support MS-CAN or SW-CAN and includes no OBD app of its own. |
| OBDLink LX | Cheaper OBDLink option with the same 2 mA sleep mode, but it is Android/Windows focused and lacks the MX+’s iOS support and advanced Ford/GM networks. |

Who Should Buy This?
Buy the OBDLink MX+ if you are an enthusiast, DIY mechanic, fleet owner, data logger, FORScan user, or someone who owns multiple vehicles and wants one flexible adapter. It makes particular sense for Ford and GM owners who can benefit from the extra network access. It is less compelling for someone who simply wants a low-cost code reader or expects a phone adapter to replace a full professional bidirectional scan tool. This OBD2 scanner vs. dealer diagnostic tool guide is useful for understanding that boundary.
Extended FAQ
Does the OBDLink MX+ work with iPhone?
Yes. The MX+ officially supports iOS, Android, and Windows. App compatibility still varies, so confirm that your preferred diagnostic app supports both your phone and vehicle.
Can I leave the MX+ plugged in all the time?
It is designed for that use case, with automatic sleep/wake behavior and a rated 2 mA low-power mode. For vehicles parked for weeks, normal battery-maintenance precautions still apply.
Can the MX+ program key fobs?
The adapter itself does not guarantee key programming. That capability depends on the vehicle, security access, and compatible software. Many immobilizer and key-learning jobs still require locksmith or dealer-grade tools.
Does it require a subscription?
No mandatory OBDLink subscription is required. The included OBDLink app and OBDwiz are available to owners, and MX+ OEM add-ons are free, but some third-party apps may charge purchase or subscription fees.
Is OBDLink MX+ better than BlueDriver?
They prioritize different workflows. MX+ emphasizes open app compatibility, fast data, Windows support, and added Ford/GM network access; BlueDriver emphasizes a simpler proprietary app with integrated repair guidance.
Will it work with every 1996-and-newer vehicle?
It supports legislated OBD-II protocols used by 1996+ U.S. cars and light trucks, but manufacturer-specific modules and advanced functions vary. Non-U.S., hybrid, and EV use may require specific apps and vehicle support.
Final Verdict
The OBDLink MX+ is one of the most capable phone-based OBD-II adapters for buyers who value flexibility more than simplicity. Its combination of broad platform support, fast live data, Ford and GM network access, secure pairing, low-power sleep behavior, and deep third-party app compatibility gives it a wider ceiling than most inexpensive dongles. The price only makes sense if you will use those advantages; for basic code reading, it is overkill. For enthusiasts and serious DIY users who want one adaptable scanner interface, however, the MX+ remains a strong long-term tool.
