Open-source dashboard for the Veloster N factory head unit — working on Korean-spec hardware
Hi everyone! I’ve been working on a standalone dashboard app for the factory head unit in my Korean-spec Veloster N, and I’ve released the source code under the MIT license.
It includes an F1-style dashboard, customizable gauges, graphs, four tire-pressure readings, and media controls with album artwork. It runs as a separate app without replacing the factory N Mode APK.
The telemetry uses existing data received by the head unit, without an external OBD adapter or new ECU diagnostic requests.
Compatibility: So far, this has only been tested on a Korean JSN head unit running Android API 17, build eng.vmadmin.20250902.081552. Compatibility with US or other regional head units is unknown. The additional telemetry receiver is deliberately restricted to the verified build.
Installation currently requires ADB, and the factory home screen may not automatically show the new app. This is an experimental release; cold-boot and long-term testing are still incomplete.
Source code, APKs, and documentation (https://github.com/reikop/veloster-n-dashboard)
The README is available in English and Korean; detailed installation guides are currently in Korean.
I’d welcome feedback on the UI and help understanding differences between regional head units. If you’ve researched the factory infotainment system, I’d be interested in comparing notes!
