GPS Plus — Auto Steering Mod for Farming Simulator 25

GPS Plus is a precision auto-steering script for Farming Simulator 25 that equips tractors, harvesters, and sprayers with centimeter-accurate guidance. The mod eliminates overlapping passes, skipped rows, and wasted seed, fertilizer, and fuel. It is designed to boost farm efficiency without requiring manual alignment of machinery. The system supports both straight AB lines and recorded curved paths for complex fields.

• Straight AB Lines: mark Point A and Point B to create perfectly parallel tracks across your field.
• Instant Heading Mode: a single keypress creates a guidance track along your vehicle's current direction.
• Fine Angle Snapping (0.5°): rotate guidance lines in 0.5° increments for alignment with roads, fences, and field boundaries.
• Lateral Track Nudge: shift the active lane left or right by 10 cm on the fly without resetting your track.
• Smooth Curve Recording (Curved AB Mode): record irregular contours, terraced hillsides, or riverbanks with cubic spline smoothing.
• Automatic Implement Width Detection: one click scans attached planters, cultivators, sprayers, or headers and sets the exact working width.
• Automatic Headland Turns: press the turn shortcut and your machine executes a clean 180° turn directly into the next swath.
• Speed and equipment management remain in your hands while automated steering handles the vehicle.

The mod also includes keyboard shortcuts for quick setup, such as Right Shift + ; for AB lines, Left Alt + W for auto pilot, and Left Alt + A/D for headland turns. It is compatible with most base-game and modded vehicles, and its smoothing algorithms ensure stable operation even on challenging terrain.
