Most leading Chinese brands' car systems support "offline voice commands" (like adjusting temperature and opening windows). However, if recognition fails due to accent or language limitations (only standard Chinese is supported), you can always control it via the physical screen.

It's extremely difficult. Unauthorized modifications can lead to module current overload protection, resulting in a lock. In China, you need to use the factory online engineer account to reprogram it. It's basically impossible to perform online decoding overseas. We strongly warn against blind electrical modifications on modern integrated circuit vehicles.

We use a calibrated high-precision paint thickness gauge to take multiple measurements on at least 13 metal surfaces of the entire vehicle. The original paint thickness of mainstream Chinese models typically ranges from 90μm to 150μm. If any area exceeds 200μm or even reaches over 500μm, we will directly conclude that the area has undergone bodywork and filler repair.
