Choosing the right OBDII scanner can be overwhelming, especially when you’re trying to balance cost and compatibility, particularly with iPhones. Many car owners are looking for affordable tools to read diagnostic codes, but iPhone users often face extra hurdles due to Bluetooth connectivity issues with some budget scanners. Let’s break down your options for effectively using OBDII tools with your iOS device.
Low-Cost OBDII Readers and iPhone Compatibility
If you’re on a tight budget, ELM327-based OBDII readers are often recommended as a starting point. These are readily available and inexpensive, but they typically come without dedicated software. While they can read basic codes, their compatibility with iPhones via Bluetooth can be problematic.

As discussed in forums like this thread on bobistheoilguy.com, finding reliable iPhone apps for Bluetooth ELM327 readers can be challenging. While some apps exist, they may not offer the seamless experience or advanced features you might need. It’s worth noting that Wi-Fi versions of ELM327 readers are generally more compatible with iPhones, as detailed in articles like this one from medium.com. However, Wi-Fi connections can sometimes be less convenient than Bluetooth.
Enhanced Features with BlueDriver and OBDLink MX+
For users seeking more comprehensive diagnostics and better iPhone integration, tools like BlueDriver and OBDLink MX+ offer significant advantages, though at a higher price point.
BlueDriver stands out for its user-friendly app (iOS compatible) and its ability to not only read codes but also provide specific repair recommendations tailored to your vehicle’s make and model.

While the BlueDriver scanner is designed to work exclusively with its own app, some users have found that you might be able to get repair reports by manually inputting your vehicle details and error codes into the BlueDriver app, even without their specific scanner. You can see an example of a BlueDriver repair report here.
OBDLink MX+ is another excellent option, especially for real-time data monitoring and enhanced diagnostics. It also boasts free enhanced code scanning that accesses manufacturer-specific error codes. While the user interface for accessing these enhanced features might feel a bit like an online store where you “purchase” support for specific car years, the functionality is now included for free. OBDLink MX+ is also compatible with iOS and is known for its fast data polling speed, which is beneficial for live data monitoring. You can see a review of the OBDLink MX+ in videos like this YouTube review.

Understanding OBDII Readers vs. Tools that Change Parameters
It’s crucial to understand that these OBDII tools are primarily readers. They excel at diagnosing issues by reading error codes and monitoring data. While they can reset error codes, they generally do not change vehicle parameters or delve into functions like unlocking a theft-locked radio. If you’re facing a situation where your car radio is locked after a battery issue or potential theft-related electrical problem, an OBDII scanner can help diagnose related electrical faults but likely won’t directly unlock the radio itself. Radio theft locks often require specific codes or procedures from the manufacturer or specialized tools beyond the scope of standard OBDII scanners.
Choosing the Right Tool for Your Needs
Both BlueDriver and OBDLink MX+ represent a step up in terms of features and reliability compared to basic ELM327 readers, and both offer ongoing support and updates, making them valuable investments for car owners. While they are more expensive than budget options, their comprehensive capabilities and iPhone compatibility can justify the cost, especially considering they often pay for themselves by helping you accurately diagnose and address car issues.
Remember that the OBDII scanner market is constantly evolving, and online reviews can sometimes be outdated. It’s always a good idea to check recent reviews and specifications before making a purchase to ensure the tool meets your current needs and iPhone compatibility requirements.
