What is the method for car navigation modification?

The method for car navigation modification is: 1. Pry up the decorative strip and pull up the clips of the decorative strip; 2. Remove the screws of the panel and the center console base, then lift the tail of the center console base upwards; 3. Pull the center console base panel backward to separate it from the vehicle audio; 4. Disconnect the power cord of the vehicle panel and remove the head unit; 5. Connect the GPS antenna and power tail wire behind the TFT screen; 6. Install the panel and storage box. Car navigation consists of a chip, antenna, processor, memory, display screen, speaker, buttons, expansion function slots, and map navigation software. The function of car navigation is positioning, monitoring, and navigation.
I used to find it quite interesting to modify the navigation system, and there are usually three mainstream methods. The first is to directly replace the original car's central control screen by finding a compatible navigation host such as Pioneer or Alpine brands, purchasing it, and having it professionally installed to ensure correct wiring connections without affecting the safety system. The second method is to add a modular navigation box connected to the OBD port. This option is more cost-effective and controlled via a mobile app, but requires regular map updates. The third and simplest and cheapest way is to use a smartphone holder with an app, but make sure it's securely fixed to avoid distractions while driving. I chose the screen replacement option, which I modified ten years ago, and it still serves me well on long trips with updated traffic conditions. An extra tip: check your car model's compatibility before modification to avoid warranty issues, and always prioritize safety—don’t block your view for a smoother driving experience.
