The automotive interior system is an important part of the car body. The design workload of the interior system accounts for more than 60% of the car design workload, far exceeding the car styling, and is one of the most important parts of the car body. Each OEM generally has a large car interior team that undertakes most of the interior-related engineering work.

Car interior modification is an important modification work carried out by car owners to meet personalized needs. Before modification, the following aspects need to be considered:
1. Function selection
Choose the appropriate functional module according to the car model and the actual needs of the user. This decision will directly affect the effect after modification.
2. Material and equipment selection
In order to achieve the same function, there are often a variety of different materials and equipment to choose from. For example, the leather covered by the interior can be divided into animal leather and artificial leather, and the audio system can be divided into domestic and imported. Therefore, the cost difference of different materials and equipment is as high as tens of thousands of yuan, and it needs to be selected according to personal needs.
3. Technical support
Car interior modification is similar to house interior decoration, involving many professional installation links. Some interior modification projects require professional designers to first produce design drawings, and professional modification personnel to carry out technical modifications based on the drawings. Some larger modification projects need to be completed in the factory. Therefore, technical support is a very important part.
4. Legality of interior modification
The modified model must have the MIIT RV modification announcement before it can be modified, otherwise it will be considered an illegal modification. Therefore, before modifying, please be sure to consider the legality of the modification.

When modifying the interior of a car, you need to follow the following principles:
1. Reasonable use of the original car design
During the modification process, it is necessary to retain the original car design as much as possible, and strive to maintain its overall beauty and coordination after the modification.
2. Focus on the combination of comfort, practicality and beauty
The modified interior environment should not only be more beautiful, but also more comfortable and practical. Therefore, when modifying, it is necessary to consider the combination of these three elements.
3. Pay attention to safety control
The safety performance of the vehicle is always the first factor. The modified vehicle is no exception, so special attention should be paid to safety control during the modification.
In short, car interior modification is a very complicated process that requires comprehensive consideration and planning. Only by choosing appropriate functional modules, equipment and materials, paying attention to technical support, and following the legal requirements of modification principles and regulations, can you further realize your own modification needs and make your car more unique.
