The memory card slot for the 2021 Mercedes-Benz E300 (GCC-spec) dash cam is located under the front passenger footwell carpet, near the center console. You'll find a small plastic cover marked with a memory card symbol; gently pry it open to reveal the microSD slot. For reliable operation in the UAE's extreme heat, which often exceeds 45°C in summer and with constant air conditioning use, avoid generic cards. Use a high-endurance, heat-resistant microSD card with a minimum capacity of 64GB and a speed class of Class 10 or UHS-I (U1) or higher. The Roads and Transport Authority (RTA Dubai) emphasizes the importance of functional recording devices for incident documentation, and the UAE Ministry of Interior (MOI UAE) notes their utility in streamlining accident reports. A low-quality card can corrupt in high temperatures, causing crucial footage from your commute on Sheikh Zayed Road to be lost. Based on common user reports from 2023-2024, a recommended setup is a 128GB high-endurance card, which typically needs formatting every 4-6 months for optimal performance in continuous loop recording.
