📙 Introduction
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.
🚀 Core Features
– Real-Time Navigation: Live GPS tracking powered by in-game telemetry.
-Second-Screen Experience: Use your phone, tablet, or browser as a dedicated GPS unit.
– Turn-by-Turn Guidance: Clear routing instructions designed for immersive driving without the in-game HUD.
– Custom Routing Engine: Built from game data to generate accurate and realistic routes.
– Cross-Platform Support: Available as desktop (.exe), mobile (.apk), and web app.
– Telemetry Integration: Direct communication with the game for position, speed, and heading.
– Mod-Aware Navigation: Designed to support company mods.
🆕 What’s New (v0.4.2)
– New UI Features
– Custom Text Colors: Added a new setting to toggle between Light/Dark text on colored components. This ensures readability regardless of your background map style.
– Reset to Defaults: Added a “Reset to Defaults” button in the settings panel to quickly revert all navigation and UI changes on the certain profile.
– Compact Maneuver Cards: Refactored the maneuver card components to be more compact, saving valuable screen space on smaller mobile devices.
– Map & Navigation Improvements
– City Logic: Improved city name detection and destination logic.
– Quality of Life: Improved the ETA and the distance of the trip to be more accurate.
– Installation Clarity: Updated the documentation with clearer steps for installing the required telemetry plugin in case is missing.
– Community & Support
– Official Discord: We now have a dedicated Discord server for bug reports and community chat.
– SCS Forums: Follow the project on the official SCS Software forums.
– Improved Reporting: The Readme.md file has been replaced so it follows the current TruckNav version with clearer steps and compatibilties.

The app works great until there’s a deviation in the route; then the app isn’t able to change the route like the game’s built-in GPS. It works very well, but I’ve had this problem. I don’t know if I’m not configuring it correctly or if it’s an app issue.
