EONON V0056 Bluetooth OBD2 Adapter for Android Stereos — Live Engine Data & Fault Code Reader

The Eonon V0056 is a Bluetooth OBD2 adapter that connects to compatible Android head units to read real-time engine data, pull fault codes, and stream vehicle parameters into apps like Torque.

Plug-and-play with EONON Android stereos, the V0056 turns your car radio into a live diagnostic display. It translates the vehicle’s OBDII bus into Bluetooth data that automotive apps can present as gauges, code definitions, and logging. This device supports standard PID metrics and manufacturer-specific trouble codes, helping you monitor performance and troubleshoot issues without needing a laptop-based reader.

Which vehicle data can the V0056 show on my Android head unit?

The adapter exposes a wide range of engine and sensor parameters so you can watch how the vehicle behaves in real time. Once paired and used with an app such as Torque, you’ll see live telemetry and historical readings for common diagnostics.

• Engine RPM, vehicle speed, and throttle position
• Coolant and intake air temperatures, intake manifold pressure
• Short- and long-term fuel trim, fuel system status, fuel pressure
• Oxygen sensor voltages, timing advance, mass air flow

How does the V0056 read and explain fault codes?

The V0056 communicates with the vehicle’s OBDII system to request Diagnostic Trouble Codes (DTCs). It returns generic and many manufacturer-specific codes; the connected Android app can then display code definitions from its database so you understand each fault’s meaning.

• Reads stored and pending diagnostic trouble codes
• Displays over 3,000 code definitions inside the app
• Requires an Android app (e.g., Torque) to view code text and freeze-frame data

What Android units and apps are compatible with this Bluetooth adapter?

The V0056 is made to work with EONON Android head units and most apps that support standard Bluetooth OBD2 protocols. Before use, install a compatible application from Google Play to visualize data, create dashboards, and log sessions.

• Compatible with EONON Android car radios and many other Android head units
• Works with Torque and other OBD2-capable apps available in Google Play
• Requires Bluetooth pairing between the adapter and the head unit

How easy is installation and what should I expect?

Installation is simple: plug the adapter into the vehicle OBDII port, pair it with your Android stereo, then open your chosen diagnostic app. No complex wiring is needed, but app setup (selecting protocol and PID lists) may be required for full functionality.

• Plug into the vehicle’s standard OBDII port — no tools needed
• Pair with the Android head unit over Bluetooth like any wireless device
• Open the diagnostic app and configure connection settings if prompted

Who is this for? The Eonon V0056 suits DIY car owners, enthusiasts, and technicians who want affordable on-board diagnostics displayed on an Android stereo. It’s especially useful for drivers with EONON head units who want live gauges, code reading, and logging without carrying a separate scan tool.
