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
