No, you cannot reliably use an INPA cable for the iCarly adapter. While both devices connect to your car's OBD-II port, they are designed for fundamentally different software ecosystems and communication protocols. Using an INPA cable with iCarly will likely result in a failure to connect or severely limited functionality.
The core of the issue lies in the electronics inside the adapter. An authentic iCarly adapter is specifically engineered to communicate with the iCarly smartphone app. It translates the commands from the app into signals your car's CAN bus (Controller Area Network) can understand. An INPA cable, on the other hand, is a specialized tool primarily for and Mini vehicles, intended for use with dedicated diagnostic software like INPA or ISTA. It often uses a different chipset, like an FTDI chip, which is not recognized or supported by the iCarly application.
Attempting to use the wrong cable can lead to communication errors, an inability to read critical data like DTCs (Diagnostic Trouble Codes), or complete failure to establish a connection. For the iCarly app to function correctly—especially for advanced features like coding or long-term data logging—you must use the genuine iCarly Bluetooth or Wi-Fi adapter. Using non-certified hardware voids any support and can potentially lead to unreliable data.
| Feature | iCarly Adapter | INPA Cable (for BMW) |
|---|---|---|
| Primary Use | Consumer-level diagnostics & coding for various brands | Professional-level BMW/Mini diagnostics |
| Compatible Software | iCarly App | INPA, ISTA, NCS Expert |
| Connection Type | Bluetooth / Wi-Fi to mobile device | USB to laptop |
| Key Chipset | Custom for iCarly app compatibility | FTDI (e.g., FT232RL) |
| Vehicle Compatibility | Broad OBD-II support (e.g., VW, Audi, BMW, Mercedes) | Primarily BMW, Mini (with 20-pin adapter) |
| Risk of Incompatibility | High if used with incorrect software | High if used with incorrect software |

Nope, it won't work. Think of it like trying to use a PlayStation controller on an Xbox. Both plug into the same spot, but they speak completely different languages. The iCarly app is designed to talk only to its own specific adapter. Using a different cable, especially a specialized one for BMWs, will just give you a connection error. Save yourself the hassle and get the right tool for the job.

You'll be disappointed if you try. I looked into this myself, hoping to save a few bucks. The problem is the hardware inside the cables. The iCarly adapter has its own "brain" that communicates with the app on your . An INPA cable is built for different, more complex software on a computer. They aren't interchangeable. For simple things like reading a check engine light, a basic generic OBD2 scanner might work, but for iCarly's specific features, you need their official adapter.

It's not recommended. The main reason is compatibility. The iCarly system, both the app and the hardware, is a closed loop. The company ensures its adapter works seamlessly with its software. Introducing a third-party cable, particularly one designed for professional diagnostics, creates a point of failure. You risk getting no data or, worse, unreliable information. If you're investing in an app like iCarly for its specific functions, using the certified hardware is part of that investment for guaranteed results.

As a car enthusiast who uses both types of tools, I can confirm they are not cross-compatible. The iCarly adapter is a consumer-grade device for a wide range of cars, focusing on usability and common features. The INPA cable is a pro-grade tool for a specific brand, dealing with deep-level module coding. Their internal electronics and communication protocols are entirely different. Using the INPA cable with iCarly is like putting diesel fuel in a gasoline engine; it simply won't run correctly. Stick with the manufacturer's recommended hardware.
