First, establish a pairing relationship between the and the Mercedes-Benz GLA's in-car Bluetooth device. Turn on the Bluetooth function on both the phone and the Mercedes-Benz GLA's in-car Bluetooth device. Then, search for Bluetooth devices on the phone. Once found, select it to pair and connect. The pairing password is: 0000. After the in-car Bluetooth and phone Bluetooth are successfully paired and connected, you can make and receive calls on the Mercedes-Benz GLA's in-car Bluetooth and play music on the phone.

















I've been driving a GLA for two years, and every time I get a new phone, I have to reconnect the Bluetooth. Remember to park the car in a safe place and keep the engine running. There's a phone icon below the central control screen—tap it and select 'Connect Device.' Then, turn on your phone's Bluetooth settings, and it will pop up with a device named 'Mercedes MB.' After clicking 'Pair,' both the car and phone will display a six-digit password. Just confirm it on both sides. Here's the key point: the first time you connect, make sure to check the boxes for syncing contacts and media audio; otherwise, you can only make calls but not listen to music. Occasionally, you might encounter connection failures, but restarting both the car's system and your phone usually solves the issue. The system responds quite quickly, and once connected, it automatically reconnects when you get in and out of the car, which is super convenient.

Last week I just helped a friend connect the on his newly purchased Mercedes-Benz GLA, and the steps were actually quite simple. After starting the car, swipe the left menu bar on the main interface to find the phone function with the Bluetooth symbol. Make sure your phone's Bluetooth is turned on and discoverable at this time. The car should detect your phone model name within about ten seconds. After clicking the pairing request, both parties need to confirm the same PIN code. Finally, rename the phone in the vehicle system to a memorable alias. Don't forget to open the advanced settings and enable both SMS and audio permissions, otherwise WeChat voice messages won't have sound. The car's Bluetooth remains effective within about 10 meters and is more stable than Apple CarPlay.

Connecting in a Mercedes-Benz GLA is straightforward and can be done in five steps: Start the vehicle; Turn on your phone's Bluetooth; Navigate to the phone menu on the central display and select 'Add Device'; Find the car's device name in your phone's list; Confirm the pairing code and remember to select all permissions. If the connection fails, delete all old phone records from the system and try again. It's advisable to name your phone with your license plate number for easier management of multiple devices. Avoid pressing buttons near the gear shift during the connection process to prevent lag.

As a frequent renter of the GLA, pay special attention to the timing for pairing. After turning the key to the power-on position, wait for the dashboard to fully light up, which takes about seven to eight seconds. Then, select the Media menu on the left side of the central control screen and switch to Bluetooth settings. Only open your phone's Bluetooth when you see the scanning interface; activating it too early might prevent the device from being found. After pairing, place your phone in the front row to avoid disconnections. Additionally, Android phones require manual enabling of the file transfer protocol to prevent music playback from stuttering. Remember to delete the previous pairing record before switching users each time.

The connection logic of the MBUX system in the Mercedes-Benz GLA is quite user-friendly. First, ensure your phone's Bluetooth visibility is turned on. After starting the vehicle, simply say 'Hey Mercedes, connect Bluetooth' to activate the voice assistant. Then follow the prompts for pairing code verification—the entire process can be completed without touching the touchpad. It's recommended to set the car Bluetooth permissions on your phone to automatically allow media audio. If song playback suddenly stutters, check if your phone is simultaneously connected to headphones or a smartwatch, which may interfere with the signal. Reconnection within two hours after turning off the engine is particularly responsive.
