In the vehicle's Bluetooth device, enable the Bluetooth function. Turn on the Bluetooth function on your phone and set it to 'Visible to other Bluetooth devices' in the phone's Bluetooth settings. Click 'Next', and the phone will automatically turn on Bluetooth and search for connectable Bluetooth devices. Once the vehicle's Bluetooth device is found, select it to pair and connect. You can make and receive calls on the vehicle's Bluetooth or play music from your phone.

When I first bought my GLC, I also struggled with Bluetooth. Here's my experience: The first step is to start the vehicle to turn on the central control screen, then use the touchpad on the right side of the steering wheel to select the phone icon. At the same time, remember to turn on Bluetooth in your phone settings, and your phone will automatically scan for device names like MB GLC. When pairing, pay special attention to ensure the verification codes displayed on both the car screen and your phone match, then click confirm to connect. After connecting, I usually check the auto-connect option in the system settings so I don't have to repeat the process every time I get in the car. One key point that's easily overlooked—if you've connected to other cars before, delete the old records to avoid conflicts. Additionally, the Mercedes system has Bluetooth version requirements, and older phones may experience disconnections.

As a business professional who frequently drives on business trips, Mercedes-Benz's Bluetooth connection is actually quite stable. First, ensure the vehicle is in the ignition state, navigate to the phone function in the main menu, enter the submenu, and select connect device. Keep your phone's Bluetooth turned on at this time, and within about 30 seconds, you should see your car model appear in the list of available devices. The pairing process requires dual confirmation – remember to check if the four-digit pairing code on the car's screen matches the pop-up window on your phone. A key recommendation is to immediately test call quality after pairing is complete. If you encounter intermittent issues, try placing your phone in the central console's wireless charging area to enhance signal strength. I've noticed that the new GLC even supports connecting two phones simultaneously – just enable the multiple connections option in the Bluetooth settings.

The operation is quite intuitive: After starting the engine, press the TEL button on the center console to enter the phone interface, then select Bluetooth device management. Enable Bluetooth search on your phone and tap to pair with the device starting with MB. When a six-digit pairing code appears, ensure it matches on both sides and press OK to complete the basic connection. I usually also check both media audio and call audio in the vehicle's communication settings to ensure normal music playback and phone calls. If there's no sound after connection, check if your phone's volume button is muted.

The connection logic is actually divided into three layers: at the hardware level, the infotainment system must complete its startup, and at the software level, the Bluetooth module's signal transmission needs to be activated. The specific operation involves rotating the central control knob to the phone icon and selecting 'Add New Device.' Once the phone's Bluetooth is turned on, it will receive a broadcast signal starting with MBT. It is recommended to set the pairing request pop-up reminder to 'Always Allow.' After that, each automatic connection upon entering the car requires 3-5 seconds of initialization time, during which the onboard computer verifies the digital certificate. If frequent disconnections occur, upgrading the infotainment system or resetting the network settings usually resolves the issue.
