What is the maximum memory capacity supported by the USB flash drive in the 2020 Mercedes-Benz GLE?
3 Answers
Mercedes-Benz 2020 GLE's in-car USB flash drive can support memory capacities of 32GB, 64GB, and 128GB. Supported formats for in-car USB flash drives: Generally, the vehicle can only recognize music files in MP3 or WMA formats. Therefore, when downloading music, it is essential to pay attention to the file format. If the format is incorrect, it must be converted to MP3 or WMA. Capacity of in-car USB flash drives: Some car infotainment systems do not support USB flash drives with excessively large capacities, especially in older models. Since the primary use of in-car USB flash drives is to store music, which does not occupy much space, it is sufficient to choose an appropriate capacity. There is no need to deliberately pursue large capacities.
When I first drove the Mercedes-Benz GLE, I always loved using a USB drive to listen to music. The 2020 model supports USB drives up to 32GB—anything larger won’t be recognized. It must be formatted in FAT32, as NTFS isn’t compatible; the system simply ignores it. I tried a 64GB Sandisk USB drive, but it wouldn’t read no matter what, while a cheaper 32GB one worked smoothly. Stick to MP3 or WAV files and avoid filling it with too many high-res audio files to save space. I recommend reliable brands like Samsung or Kingston to minimize connection issues. If storage runs low, using multiple USB drives in batches or switching to Bluetooth via your phone is more convenient than fiddling with it while driving.
From a technical perspective, the 2020 Mercedes-Benz GLE's infotainment system is based on USB interface and can only support USB drives under 32GB due to the FAT32 file system limitation, which doesn't support large-capacity devices. If exceeding 32GB, the system will automatically deny access, and even forced formatting won't work. Through my modification tests, I found MP3 or AAC are the optimal music formats—avoid FLAC as its large file size causes issues. For device compatibility, avoid low-quality USB drives prone to lagging; prioritize high-speed read/write models. Also, regularly defragment your USB drive to prevent playlist disorder affecting driving experience.
