Can the 2019 Haval F7 Be Upgraded to the 2021 Model's Infotainment System?
3 Answers
It can be upgraded to the 2021 model. Below is the relevant introduction to the 2021 Haval infotainment system: 1. UI Upgrade: The new Great Wall infotainment system features a unified design language, making it highly recognizable. The screen quality is excellent, with resolution and color performance comparable to smartphone screens, and it also offers excellent touch response. 2. Configuration Upgrade: The media system uses Android 8.0 Automotive, a version of Android specialized for in-car multimedia hosts by Google, with 4GB of RAM and 32GB of storage memory, providing more extended functionalities and smoother operation. The telematics system has been upgraded from Bosch's third generation to Valeo's fourth generation, featuring an independent T-BOX that supports 4G communication and FOTA online upgrades.
I've noticed many owners want to upgrade their 2019 model head unit to the 2021 version, but it's actually quite complicated. The key is whether the hardware interfaces are compatible—things like the screen ribbon cable and main unit slot must match. The 2021 head unit's panel might be slightly larger, requiring dashboard disassembly and bracket modification for proper fitment. Software flashing is also necessary, especially for steering wheel button mapping and reversing camera calibration—mistakes here could cause malfunctions. I'd recommend against DIY attempts; instead, find a Haval-specialized workshop. They have proper tools, extensive experience, and can test compatibility thoroughly. The whole process takes about half a day, with parts and labor costing around 2,000 RMB—justifiable given the intensive wiring work. After installation, remember to test Bluetooth connection stability and voice control response speed.
This modification depends on the specific situation. The 2021 model's infotainment system has an upgraded processor, making it much faster, but the 19 model's older circuitry may not be compatible. Focus on checking three key areas: whether the main unit's power supply voltage matches, if the USB interface protocols are compatible, and whether there are extra interface slots on the back of the infotainment system. You'll need to prepare adapter wiring harnesses for the modification, otherwise, the steering wheel's volume buttons and track skip functions may stop working. Also, the built-in map navigation on the new infotainment system might require reactivation, and there's a risk of crashes if software cracking is involved. It's recommended to first compare the data manuals of both infotainment systems using a computer or join a Haval car owners' group to ask about actual modification cases.
