A CarPlay-inspired navigation companion for the Royal Enfield Tripper Dash (Guerrilla 450, Himalayan 450, and compatible round TFT displays). Recon Dash streams offline turn-by-turn navigation and a live map to the bike's cluster over Wi-Fi, and turns the phone into the setup/companion screen so the rider keeps their eyes on the road.

- Offline-first navigation — on-device routing (Valhalla) and pre-cached vector map tiles (PMTiles); no data connection needed during a ride.
- Dash projection — streams a live navigation map to the bike's display over the K1G protocol (H.264 over Wi-Fi), or sends turn-by-turn only in analogue mode.
- CarPlay-style UI — dark, glanceable, single-purpose screens with a gold accent.
- Search — Photon (OSM) with an optional Google Places layer for local POIs.
- Ride history, favorites, wallpapers, and a telemetry lab for decoding the dash's instrument data.
Kotlin · Jetpack Compose · Hilt · Room · Coroutines · MapLibre GL · Valhalla (on-device, JNI) · a C++/NDK geo hot path.
./gradlew :app:assembleDebug # debug APK
./gradlew :app:testDebugUnitTest # unit testsRequires the Android SDK (set sdk.dir in local.properties) and, for the native geo layer, the NDK + CMake. The prebuilt Valhalla routing library is not committed — see valhalla/README.md for how to fetch it.
local.properties (git-ignored) may hold an optional GOOGLE_PLACES_KEY to enable the Google Places search layer; without it the app falls back to Photon.
Under active development. Navigation reliability is the current focus. Hardware-validated on Guerrilla 450 and Himalayan 450 (firmware 11.63).
