What is the reason why Bluetooth cannot be found on BMW 3 Series?
2 Answers
Due to compatibility issues with Bluetooth devices. In this case, it is recommended to delete the pairing and reconnect. Below is the relevant introduction: 1. Bluetooth: It enables wireless information exchange between numerous devices including mobile phones, PDAs, wireless headphones, laptops, and related peripherals. Utilizing "Bluetooth" technology, it can effectively simplify communication between mobile communication terminal devices and also successfully simplify communication between devices and the Internet, making data transmission faster and more efficient, thereby broadening the path for wireless communication. 2. Wireless connection technology: As a small-range wireless connection technology, Bluetooth enables convenient, fast, flexible, secure, low-cost, and low-power data and voice communication between devices, making it one of the mainstream technologies for wireless personal area network communication.
My old BMW 3 Series also had Bluetooth connection issues before, took several attempts to figure it out. The Bluetooth function in the infotainment system might have been accidentally disabled—you'll need to check its status in the settings menu on the center display. If your phone's discoverable mode isn't activated or location permissions aren't granted, the car's system won't detect it. Another common issue is when the car's Bluetooth pairing list is full; you'll have to delete some old devices before adding a new phone. System freezes can also occur—usually holding down the volume button to reboot the head unit does the trick. By the way, Android and Apple connect differently; iPhones require selecting 'New Device' in iDrive for re-pairing. If none of these steps work, it might indicate a hardware failure in the Bluetooth module, necessitating dealership repair.
