ETS2 Tunnel Radio — realistic radio signal loss in tunnels for Euro Truck Simulator 2

Description
Versions 1

Ever noticed the in-game radio plays at perfect quality inside tunnels? In real life it would drop to static. Tunnel Radio fixes that.

Drive into a tunnel and your radio fades into crackling static — drive out and the music returns. One click makes ALL your existing in-game stations tunnel-aware (names, order, and the radio UI stay exactly as they are); one click restores your original list.

FEATURES

- +500 tunnels detected automatically from the game's own covered-space map data

- Works through the real in-game radio — volume and UI behave as always

- 10 different procedurally-generated static sounds, a different one every tunnel

- Realistic: short bridges and underpasses do NOT cut the signal, only real tunnels (200 m+)

- Manual tunnel tagging for map mods (Tag Entry / Tag Exit)

- Shows your game version vs. database version and warns on mismatch

- Lives in the system tray while you play

Supported Game Versions: 1.57 15

🚇 Automatic tunnel detection — a database of every tunnel in the map, built from the game's own "covered space" zone data (the same data the game uses to stop rain and add reverb inside tunnels). No manual setup for known tunnels.
📻 Works with the real in-game radio — one click reroutes your existing station list through the local tunnel engine. You keep your stations, names and order; the in-game radio UI and volume behave exactly as before.
🎚️ 10 different static flavors — FM hiss, AM crackle, storm static, a distant station bleeding through, and more. A different one every tunnel, so it never gets repetitive. All procedurally generated (no copyrighted samples).
🏷️ Manual tunnel tagging — for map mods or missed tunnels: press Tag Entry at the portal, Tag Exit at the other end. Saved forever, survives updates.
📏 Realistic threshold — short underpasses and bridges do NOT kill the signal; only genuinely long covered stretches (200 m+) do, like real life.
✅ Version aware — the app shows your game version, the tunnel-database version, and the telemetry plugin revision, and warns clearly if they don't match.
