Why Can't My Phone Find the Bluetooth of My Buick Car?
3 Answers
The reasons why the Bluetooth of a Buick Envision cannot be found by a phone include the car's Bluetooth not being turned on or the call audio not being selected. Below are the solutions for when the Bluetooth of a Buick Envision cannot be found by a phone: Car Bluetooth Not Turned On: Check if the car's Bluetooth switch is turned on. If the car's Bluetooth is not turned on, simply turn it on. Restart the phone and search for the connection again. Call Audio Not Selected on Car Bluetooth: Sometimes, the car's Bluetooth cannot connect because the call audio is not selected. If the call audio is not selected on the car's Bluetooth, you can turn on the car's Bluetooth and select the call audio. After the car's Bluetooth is successfully paired and connected with the phone's Bluetooth, you can make and receive calls; play music on the phone, and enjoy it on the car's Bluetooth device.
I've also encountered situations where the Bluetooth in a Buick car couldn't be detected. There are usually several common reasons to consider. The vehicle's Bluetooth settings might not be in discoverable mode, so you need to check the Bluetooth settings page on the central control screen to see if the pairing function is turned on. Sometimes, the Bluetooth cache on the phone can cause issues—try deleting all saved vehicle records in the phone's settings and then restart the phone. Some Buick models have distance limitations for the Bluetooth module, so it's best to operate within 1 meter of the car. If the vehicle's battery voltage is low, the Bluetooth function might fail; check the dashboard for any warnings. Older Android phones might have protocol compatibility issues, so it's advisable to update the phone's system version. If all else fails, disconnect the negative terminal of the car battery for five minutes with the vehicle turned off, which essentially forces a reboot of the car's computer.
As an enthusiast who frequently interacts with in-car systems, I believe the inability to find Bluetooth depends on the situation. Buick's in-car Bluetooth has a pairing limit, and it may have already connected to 8 devices, preventing the discovery of new ones. In hot weather, electronic devices can overheat, causing intermittent malfunctions—try again after the car interior cools down. If the in-car multimedia system version is outdated, it needs an update; just visit a 4S shop to connect to a computer and upgrade the TCU module. I've also noticed that having both a mobile hotspot and Bluetooth enabled on a phone can cause conflicts—try turning off the personal hotspot. Additionally, note that activation methods vary across Buick models: the Envision requires shifting to P gear, while the Excelle needs the brake pedal pressed to start before Bluetooth can be detected.
