TruckNav is a FREE and open-source, low-latency second-screen GPS companion for Euro Truck Simulator 2 and American Truck Simulator. I built this to allow for full immersion by turning off the in-game HUD and using a real-world style navigation unit on a phone, tablet, or secondary monitor.
Key Features in v0.4.0

Overhauled Routing Engine: The core routing engine has been completely rebuilt. Not only does it now feature true turn-by-turn guidance, but the routing logic itself is significantly better generating highly accurate, correct paths everywhere on the map that now properly respect one-lane roads.
Bug fixes in v0.4.1
Connectivity Fix: Added automatic firewall inbound rules for both the TruckNav App and the Telemetry Bridge. This resolves "Could not connect" issues by automatically authorizing the app on your local network.
Note: On the first launch of this version, you will be asked for Administrator permission (UAC). Please click "Yes" to allow your phone to connect to your PC.
UI Polish: Fixed a bug where turn-based navigation text was dark and unreadable on devices using Light Mode.
Mod Compatibility: Added full navigation support for "Real Companies" mods across both ATS and ETS2.
Smarter Job Routing & Map Polish: Navigating to external jobs will now intelligently route you directly to the source company pickup location. I've also deeply optimized the global road network for cleaner visual lines.
Custom Telemetry & UI Polish: Implemented a brand-new custom telemetry system, added a desktop system tray menu, and ensured your manually entered IP addresses now successfully save upon exit.
Installation
- Launch the TruckNav Desktop app to see your IP address and for the telemetry to launch.
- Open the app on your phone and enter that IP.
- Drive!
- Local Webserver: Serve the GPS interface to any device on your local network directly from the Desktop App.
- Telemetry Refactor: Restructured core logic for improved stability and fixed persistence issues on app exit.
- Map Geometry Fixes: Improved intersection accuracy in Laredo, Brownsville, Texas, Kennewick, and Salt Lake City.
- Project Governance: Officially licensed under GNU GPL v3 with new security and contributor policies.
