Automatic reconnects with clear adapter/ECU diagnostics. DTC codes persist across reboots.
- **Real GPS tracking** — Waveshare SIM868 GNSS HAT with GPIO PWRKEY auto-power-on. Live position
plotted on an offline Leaflet map (pre-cached tiles, no internet needed).
- **WiFi hotspot** — auto-switches between home WiFi and a self-hosted AP for in-car phone access
at `http://yaris.local` (no port number). Phone hotspot uplink supported for on-the-road sync.
- **WiFi hotspot** — fast 5GHz in-car AP on the T3U (wlan1), internet uplink (home WiFi +
phone hotspot) on the onboard radio (wlan0). SSID/password configurable from the Settings page.
- **Dashcam workflow** — auto-detects any USB dashcam, mounts read-only, browses files before
importing. Import one, selected, or all files. Delete individual or all files directly from the
dashcam. Verified against real 28GB/87-file hardware.
