For car enthusiasts and those keen on vehicle diagnostics, On-Board Diagnostics II (OBD2) scanners are invaluable tools. They allow you to tap into your car’s computer system, read diagnostic trouble codes, monitor live data, and much more. Many users prefer the convenience of Bluetooth OBD2 adapters that wirelessly connect to their devices. If you’re an iPhone user, you might wonder if you can leverage this technology, especially if you’ve jailbroken your device. The short answer is yes, but there are specific considerations and costs involved.
The standard ecosystem of Apple devices, while lauded for its security and user-friendliness, imposes certain restrictions. Direct Bluetooth OBD2 connectivity isn’t natively supported in the way it is with Android devices. Apple’s iOS environment is more closed, which presents a hurdle for direct communication with OBD2 adapters via Bluetooth for diagnostic purposes. Typically, apps designed for OBD2 on iPhones might rely on Wi-Fi connections to bypass these Bluetooth limitations, or utilize specific hardware certified under Apple’s MFi (Made for iPhone/iPad/iPod) program.
However, jailbreaking your iPhone changes the game. Jailbreaking is the process of removing software restrictions imposed by iOS, granting you deeper access to the operating system. This opens up possibilities that are otherwise unavailable on a stock iPhone, including the ability to establish Bluetooth connections with devices that are not officially supported. By jailbreaking your iPhone, you can install tweaks and apps that bridge the gap, enabling Bluetooth communication with OBD2 scanners. One key component often mentioned in achieving this connectivity is RoqueBT4. This type of software acts as a bridge, allowing your jailbroken iPhone to recognize and communicate with Bluetooth OBD2 adapters.

Once you’ve jailbroken your iPhone and potentially installed necessary Bluetooth enabler software, the next step is choosing the right OBD2 application. This is where iPhone users often encounter a significant difference compared to their Android counterparts. While Android users have access to budget-friendly and highly capable apps like Torque Pro, the iOS app landscape for OBD2 diagnostics tends to lean towards the premium end. Two of the most frequently recommended and robust apps for OBD2 functionality on jailbroken iPhones are DashCommand and Rev.
DashCommand is known for its comprehensive features, user-friendly interface, and extensive customization options. It provides real-time data displays, performance monitoring, diagnostic code reading and clearing, and much more. Rev, another popular choice, offers similar functionalities with a focus on visual appeal and ease of use. Both apps are highly regarded for their performance and reliability in delivering accurate OBD2 data on iOS. However, the catch is their price point. DashCommand and Rev are significantly more expensive than many comparable Android apps. You might be looking at a cost in the range of $30-$50 for a full-featured OBD2 app on iOS, whereas a top-tier Android app like Torque Pro is a fraction of that cost.

In conclusion, using a Bluetooth OBD2 scanner with a jailbroken iPhone is indeed feasible. Jailbreaking bypasses iOS limitations, and with the right software and OBD2 app, you can access your vehicle’s diagnostic information wirelessly. However, be prepared for the higher costs associated with OBD2 apps in the Apple ecosystem. While the functionality is there, the investment is notably greater than what Android users typically encounter. If you are committed to using your iPhone for OBD2 diagnostics and are comfortable with jailbreaking, apps like DashCommand and Rev offer powerful solutions, albeit at a premium price.
