What is the reason why the Bluetooth in the 2011 Tiguan cannot be turned on?

It may be due to instability in the car's Bluetooth module or unstable signal connection. Here is relevant information: Function: The car Bluetooth automatically identifies mobile phones, allowing connection without cables or phone holders; the owner can control the phone without touching it, even keeping both hands on the steering wheel, using voice commands to answer or make calls. Working Principle: Bluetooth technology is an open global standard for wireless data and voice communication. Its essence is to establish a universal radio air interface for communication environments between fixed or mobile devices, further integrating communication technology with computer technology, enabling various 3C devices to communicate or operate within a short range without wires or cables.
For the 2011 Tiguan's Bluetooth not turning on, I think it might be due to the aging system of older models, similar to issues I've encountered with my old car. The causes are often software bugs or hardware module failures, such as poor contact in the Bluetooth control unit's circuits after prolonged use, or outdated firmware leading to poor compatibility with phones. First, try restarting the car's multimedia system by turning off the engine and waiting a few minutes before trying again. If that doesn't work, check if the phone settings are correctly paired or try with a different phone. The Bluetooth in a 2011 car isn't very advanced, so software updates might be crucial. Taking it to a 4S shop for a computer diagnosis can confirm if a module replacement is needed, costing a few hundred dollars. Don't delay this, as it could affect the convenience of listening to music or using navigation while driving. Regular maintenance checks on the electronic systems can help prevent such issues.
