To address the issue of the infotainment system freezing in your 2020 Toyota Corolla E210, follow these detailed steps. This issue can manifest as the screen becoming unresponsive, slow to respond to inputs, or completely freezing. Here’s how you can diagnose and potentially fix the problem:

Symptoms:
