Electrical system
The 7920520-XJX702SY In-Vehicle Information Terminal Display Assembly is engineered as an original-equipment (OE) grade component, exclusively tailored for Dongfeng Xinjiang’s heavy-duty truck series (including models such as the Tianlong KL, Tianlong VL, and Shengtian). Its mechanical structure, interface pinout, and mounting dimensions strictly align with Dongfeng Xinjiang’s factory specifications, ensuring seamless replacement and integration with the vehicle’s existing electronic control system—eliminating the need for additional modifications during installation

Warranty: 1 YEARS ,Part name: Display Assembly 7920520-XJX702SY
PRODUCT DESCRIPTION
High-Definition, Automotive-Grade Display Performance
Equipped with an 8-inch (or customizable size based on vehicle configuration) high-brightness LCD panel, this assembly delivers a resolution of 1280×800 pixels, supporting 16.7 million color reproduction. The display features anti-glare and anti-fingerprint coating, maintaining clear visibility even under direct sunlight (with a maximum brightness of 500 nits) and resisting smudges from frequent operation. It also supports wide viewing angles (170° horizontal/160° vertical), allowing drivers and co-drivers to read information (e.g., navigation maps, vehicle status data) without visual distortion
Rugged Durability for Harsh Automotive Environments
Compliant with strict automotive-grade standards (ISO 16750 and AEC-Q100), the 7920520-XJX702SY assembly is built to withstand extreme operating conditions. It operates reliably within a temperature range of -40°C to +85°C, resists high humidity (up to 95% non-condensing), and meets IP6K4K dust and water resistance ratings—protecting internal components from road dust, splashes, and vibration (passing 50Hz-2000Hz random vibration tests with acceleration up to 30G). The housing is made of flame-retardant ABS plastic (UL94 V-0 rating), enhancing safety in case of electrical anomalies
Integrated Multi-Functional Information Management
As a core part of the vehicle’s infotainment and telematics system, this assembly integrates multiple functional modules: it displays real-time vehicle data (engine speed, fuel consumption, tire pressure, and fault codes) via CAN bus communication, supports Bluetooth hands-free calling, USB media playback (MP3/MP4/JPEG formats), and seamless connection with smartphone mirroring (Apple CarPlay/Android Auto). It also interfaces with the vehicle’s GPS navigation system, providing turn-by-turn directions with voice prompts, and can display rearview camera feeds (when paired with an optional camera module) for enhanced parking safety
Plug-and-Play Electrical Interface & Low Power Consumption
The assembly adopts a standardized 24V automotive power supply interface (compatible with Dongfeng Xinjiang’s heavy-duty truck electrical system) and features overvoltage, overcurrent, and reverse-polarity protection to prevent damage from electrical fluctuations. Its average power consumption is less than 8W during normal operation (and less than 1W in standby mode), minimizing impact on the vehicle’s battery life. The plug-and-play design—with a dedicated wiring harness matching the model’s OE connector—enables quick installation by technicians, reducing maintenance downtime for commercial fleets
TECHNICAL SUPPORT
1. Accessories selection consultation
- Provide ** intelligent selection tools ** (such as parts matching query system), input the vehicle model VIN code or engine model to match the corresponding parts number, reducing the selection error rate.
The technical team is available online 7×12 hours to answer technical questions about accessories (such as material compatibility and installation processes).
2. Customized development support
We offer specialized R&D services for special market demands (such as heat dissipation accessories for high-temperature regions in the Middle East and dedicated suspension components for road conditions in Africa), and complete sample delivery within six weeks.
3. Training and Technical materials
Provide remote/on-site training for the customer's after-sales team (such as diagnosis of electrical control accessories and DPF regeneration operation), along with multilingual versions of the "Accessories Installation Manual" and "Troubleshooting Guide".
4. Quality Traceability and Improvement
Through the QR code traceability system (one product, one code), track the production batch of accessories and the source of raw materials, respond quickly to quality complaints and initiate improvement processes.
AFTER-SALES AND LOGISTICS SUPPORT
After-sales service
Quality Assurance Policy
-The warranty period for original factory parts is 12 months (counting from the date of signature for receipt), covering material defects, process issues, and man-made damage.
- Provide "Localized Express repair Service" : Cooperate with third-party repair networks in markets such as Southeast Asia and the Middle East, and deliver emergency parts to designated repair points within 4 hours.
Return and Exchange Process
-The customer is required to submit the test report (such as a third-party appraisal) within the warranty period. After confirmation by Dongfeng, a reissue or refund will be arranged within 5 working days.
Logistics support
