There are a total of three USB ports in the GLC, with two located inside the center armrest and one at the rear air conditioning vents. More details about car USB ports are as follows: Location of USB ports: The position of USB ports may vary depending on the vehicle model. Generally, car USB ports are located on the central dashboard, inside the center armrest, or near the rear air vents. Owners can refer to the vehicle's user manual to locate the USB ports inside the car. Functions of USB ports: USB ports can be used to connect a USB drive to the car, allowing the vehicle's multimedia entertainment system to play songs from the drive. They can also connect external devices like smartphones for screen mirroring or connectivity purposes. Additionally, USB ports can provide power to car dash cams.

















From my experience helping friends with car issues, I've noticed that the USB ports in the GLC are mainly located inside the center console. Open the compartment between the driver and front passenger seats, and you'll find them at the very back—some are Type-C. Rear passengers have USB ports conveniently placed below the air vents, perfect for child seats or charging phones. Post-2022 models even include a wireless charging pad up front; I tested it, and phones fit just right. These spots can be tricky to locate while driving, as seats might block the view, so it's best to handle this when parked. For older models with different port placements, the owner's manual is your best bet—some imported versions hide USB ports on the side of the glove box.

Last time I drove my friend's GLC, I specifically noticed the interface layout. The front USB ports are deep inside the center console—you'll need to move aside the clutter to see them, so remember to bring a Type-C adapter. There's also a 12V power socket in the storage compartment below the AC panel, not a USB port, so don't get them confused. The rear USB ports are definitely easy to find, located right below the rear AC vents in the middle between the two seats. During long drives, rear passengers can charge their devices without squeezing to the front, and in my test, the charging speed was faster than using a cigarette lighter adapter. The ports in the center console can also connect to CarPlay—just plug in the cable and the Apple interface pops up automatically.

As an owner who has driven three different GLC models, I'm very familiar with the USB port locations. The most frequently used one is inside the front armrest compartment - it's deeply hidden but essential for CarPlay connection. The rear USB ports are positioned right below the air vents, which makes charging tablets for kids during trips super convenient. Since the 2020 model year, the armrest compartment has been equipped with two Type-C ports, completely replacing the old round connectors. When installing my dashcam, I discovered a spare port along the windshield's upper edge - perfect for clean wiring without visible cables. There's actually a 12V power outlet on the left side of the trunk too, which proves extremely useful for powering fridges during camping trips.

Remember when the salesperson demonstrated during pickup, the GLC's USB ports are mainly in three locations. The deepest port inside the front armrest supports data transfer – this is the one to use for mirroring. The two ports under the rear AC panel are for charging only, don't plug into the wrong ones. In older models, the center console storage had regular USB ports, but the 2022 version has all been upgraded to Type-C. When installing upgraded audio, the technician mentioned there's a pre-wired port location on the left side of the trunk, and adding a USB expansion box isn't difficult. Note that some ports will power off after engine shutdown, so remember to unplug devices promptly.

Tips for locating GLC charging ports while helping neighbors: The front row port is the most hidden, situated at the innermost part of the center console, with the newer models featuring flat Type-C ports. For the rear, crouch down and check below the air vents behind the center armrest to find it. There's also a power source near the LATCH anchors for child safety seats, though it's not USB-standard. It's advisable to purchase a multi-port car charger for the cigarette lighter, which charges three times faster than the factory option. A friend at a modification shop mentioned that there are pre-wired lines in the A-pillar, used when installing a HUD. Mercedes designs these port locations to be quite concealed, so it's normal not to find them on the first try.
