Can Dynamic Reversing Trajectory Be Installed as an Aftermarket Feature?

Dynamic reversing trajectory can be installed as an aftermarket feature. To add dynamic reversing guide lines, it's necessary to obtain the steering angle data of the front wheels, which requires installing a steering angle sensor. Only then can the guide lines on the central control screen's reversing camera become dynamic. These dynamic guide lines change according to the steering wheel's rotation, indicating the area the rear of the vehicle will pass through when reversing at the current wheel angle. The guide lines adjust with the wheel direction, overlapping with the positioning area when the wheels are straight. When the driver operates the vehicle in reverse, the intelligent trajectory reversing system displays two guiding lines on the DVD reversing camera function, representing the trajectory of the rear wheels.
Having driven for decades, I can confirm that rearview trajectory systems can indeed be retrofitted. Many older cars didn't come with this feature from the factory, but aftermarket installation significantly improves convenience and safety. I personally tried installing one on a van by visiting a reputable repair shop. They combined a camera and sensors mounted near the rearview mirror and connected the wiring to the central display. The whole process cost around 1,000 RMB. It was quite straightforward, but it's important to choose waterproof products to avoid short circuits on rainy days. After installation, the screen displays trajectory lines that move with the steering wheel, making it easier to judge obstacle positions and reducing the risk of scratches. I highly recommend this for middle-aged and elderly drivers, as it provides valuable assistance when reaction times slow with age. Just remember to check the wiring connections during routine maintenance to ensure everything stays secure.
