I also encountered the issue of Bluetooth not connecting to devices while driving my Lexus, which was very frustrating. It could be due to interference with the Bluetooth module or the phone not entering pairing mode. Try parking and turning off the engine for a few minutes, then restart the car's system: hold the power button for about ten seconds for a hard reset; turn the phone's Bluetooth off and on again, ensuring it's visible; clear the old pairing list in the car's system—sometimes it's full and can't add new devices. Also, check for updates to the car's software; the latest firmware can be downloaded from the official website or a 4S shop to fix some bugs. If that doesn't work, take it to a professional shop to check the hardware—they can use diagnostic tools to test if the module is faulty. Minimizing intensive Bluetooth operations while driving can extend its lifespan, so maintain good upkeep. A simple tip: regularly back up pairing information as a backup.
For friends who frequently repair cars, Bluetooth pairing failures are often caused by software conflicts or signal interference. Here are some methods: First, ensure the device is in a discoverable state, such as by turning on Bluetooth settings; second, perform a hard reset of the infotainment system—hold the volume button for 10 seconds to reset; third, clear old Bluetooth records from the vehicle; fourth, update the vehicle's software version. If it still doesn’t work after repeated attempts, it may be due to a faulty Bluetooth receiver or antenna, requiring professional tools for diagnosis. Avoid operating in high-temperature or strong electromagnetic field areas. As an additional tip, check the official website for a list of compatible devices to confirm support and prevent similar issues.
