. Why does the multimedia screen in my Mercedes-Benz E-Class freeze o r go blank during use?

I have a Mercedes E-Class W212, and the central infotainment screen sometimes freezes o r goes black, especially during long drives o r hot weather. Sometimes it resets on its own, other times it stays unresponsive. Is this a common issue in Pakistan, and could it be related to battery voltage, heat, o r software bugs?

This is a common issue in many E-Class models especially W212 and early W213 in Pakistan and can be caused by several factors:

Common Causes:

Overheating: High cabin temperatures, especially in summers, can affect the COMAND o r infotainment unit.

Software glitches: Outdated firmware o r corrupted data may cause the system to freeze o r restart.

Weak o r fluctuating battery voltage: Common in older batteries o r with aftermarket accessories drawing excess power.

Loose wiring o r head unit failure: Dust, heat, and humidity can damage wiring connections over time.

What to Do:

Have the infotainment system software updated at a Mercedes specialist.

Ensure the car battery is strong and charging correctly.

Avoid installing unapproved accessories e.g., cheap reverse cams that draw power from the infotainment system.
