Once the car system (especially in a closed ecosystem) undergoes a major version upgrade, its bootloader is usually locked, preventing downgrades. If this happens, there is basically no solution in an overseas environment. Therefore, we strongly warn: do not blindly insert a USB drive to upgrade while offline.

Do not use a high-pressure water gun directly! The high-pressure water can instantly damage the fragile aluminum fins of the condenser, leading to a permanent decrease in cooling efficiency. We can only use a low-pressure air gun or a soft brush for surface cleaning.

Both are common, and the right choice depends on budget and destination: 1. Container shipping (20ft/40ft): The car is sealed inside a container, offering better protection and allowing you to load spare parts inside the car. Typical cost from Shanghai to major world ports: $1,500-$3,000 per car. Best for long distances and high-value vehicles. 2. RoRo (roll-on/roll-off): The car is driven onto the ship and secured on deck. Cheaper ($800-$1,800 to most ports) and faster to load, but exposed to weather and port handling. Not all routes offer RoRo service. Transit time examples: to the Gulf 15-25 days, to West Africa 30-45 days, to Latin America 25-40 days, to Europe 20-35 days. Ask your exporter which option serves your destination port, and always insure the shipment for full value.
