How to Fix
The first step is checking for infotainment software updates and applying the latest over-the-air or dealer-installed package. If the problem persists, dealers typically inspect the infotainment control module, display connections, camera module communication, and network faults on the vehicle's Ethernet/CAN architecture. In some cases, module replacement or reprogramming is required if repeated hard resets do not resolve the issue.
