Why can't older Mercedes models play music via Bluetooth?

If the Bluetooth music connection is not producing sound, it may be because the multimedia volume on the phone is not turned on. Here is some relevant information about car Bluetooth: Function: After successfully pairing the Bluetooth function, you can use your phone to play audio files or answer calls, which is very convenient. While driving, it ensures road safety. Once the car's infotainment system is connected to the Bluetooth system, you can make calls directly through the infotainment system in hands-free mode. Automatic connection: Once the phone and car system are connected, they will automatically reconnect the next time you use them, provided the phone's Bluetooth is turned on. This eliminates the need for frequent reconnections, saving time and adding convenience to vehicle use. However, when using Bluetooth calls, be mindful of privacy.
As someone who often drives an older Mercedes, I find it quite common for Bluetooth to not play music. Many older models have limited Bluetooth functionality, possibly only supporting the HSP protocol for calls without the A2DP compatibility for audio streaming. Try checking your phone settings to ensure media audio output is selected during pairing; if it's accidentally set to call mode only, music won't play. It could also be that the car's system software is too outdated to upgrade, or the module is aging with poor contact. I suggest first testing with another phone to rule out device issues. If that doesn't work, adding a Bluetooth adapter plugged into the cigarette lighter can solve the problem for just a few dozen bucks. Don’t rush into major repairs to avoid unnecessary expenses. Last month, I added one of these, and now I can play music freely—it’s quite convenient. In short, start with simple troubleshooting methods to avoid over-intervention.
