I did both, as two separate installs - a Pioneer 1-DIN head unit that drives the speakers and sub, and a rooted, degoogled tablet that handles navigation and shows the live dashboard from the OBD Pi. The fiddly part of the radio is one connector; the fiddly part of the tablet is making Android behave like an appliance.https://archworks.co/posts/clio-obd-telemetry-pi/Sat, 30 May 2026 00:00:00 +0000https://archworks.co/posts/clio-obd-telemetry-pi/A Raspberry Pi 4 in the car reads ~20 sensors off the OBD-II port over a Bluetooth dongle, logs them to a local time-series database, and shows them on a custom touch HUD and Grafana. The interesting parts: estimating which gear you are in with no gear sensor, and surviving the fact that turning the key off is a hard power cut.
