How to Connect a Phone to the Bluetooth in a Mercedes-Benz E300L?

First, establish a pairing relationship between the phone and the car's Bluetooth device. Turn on the Bluetooth function on both the phone and the car's Bluetooth device, and set the phone's Bluetooth to 'Visible to All'. Then, search for Bluetooth devices on the phone, and once found, select to pair and connect. After completing the above steps, the pairing password is: 0000. Once paired, the connection will be successful.
Last time I helped a friend set up Bluetooth pairing for their Mercedes-Benz E300L, I realized it requires precise step-by-step operation. First, get in the car, start the ignition to power up the center display, then press the phone icon button on the left side of the steering wheel or directly tap the screen to locate the 'Phone' function. Here's the crucial part: when entering 'Connect New Device', the phone will automatically display a pairing notification – make sure to keep your phone screen awake to confirm the authorization code. Many people fail to connect because they skip the final confirmation step after entering the password. There's a significant difference between Apple and Android devices: Apple automatically syncs contacts after connection, while Android requires manual authorization in the Mercedes system to access contact permissions. If connected but no sound, remember to check both 'Media Audio' and 'Call Audio' in the car's Bluetooth settings. For older phone models that occasionally disconnect, upgrading the vehicle's system or resetting network settings usually solves the issue.
When using Bluetooth frequently to pick up and drop off kids in the E300L, I've figured out the smoothest connection method. First, start the vehicle and wait for the infotainment system to fully load, then simply say 'Hey Mercedes, turn on Bluetooth' for convenience. Enable Bluetooth visibility on your phone first, then search for your phone model in the car's device list and tap it. At this point, the car will display a pairing code. The key point is that the passwords entered on both the phone and the car's system must match exactly—a parent in our group chat had to retry three times because of a single wrong digit. After connecting, it's recommended to set the priority to the highest in the 'Device Management' section of the car's system; otherwise, other family members' phones might automatically connect. I discovered a unique feature of Mercedes: it can connect two phones simultaneously—one for calls and the other for playing music, allowing parents to handle work calls and play children's songs without interruption while driving. After turning off the car, it usually reconnects automatically the next time you get in.
The Bluetooth connection logic of the Mercedes-Benz E300L is quite scientific. For the initial pairing, operations are required on both ends: enter the phone interface on the car's infotainment system to select 'Connect Device', and enable Bluetooth on the phone to search for the vehicle model (usually prefixed with 'Mercedes-Benz'). When a 6-digit code pops up on the car display, immediately input the exact same number on the phone. Key note: Android 12 and above often automatically blocks device permissions, requiring manual authorization of call log permissions in settings. If the connection is interrupted and cannot be re-established, resetting the car's infotainment system is faster than restarting the vehicle—press and hold the volume knob for 20 seconds. There was an instance where a firmware bug caused intermittent music playback, which was resolved by upgrading to the latest system at the dealership. It's advisable to regularly clean up old phone records in the device list.
