Why can't the car connect to the phone?

[StGianna]

The reasons why the car Bluetooth cannot connect to the phone include Bluetooth being in an invisible state, excessive distance, changed Bluetooth name, and hardware issues. Bluetooth being in an invisible state: If either the car Bluetooth or the phone Bluetooth is in an invisible state, neither device can scan the other, making it impossible to pair and connect. Solution: Set the car Bluetooth or phone Bluetooth to a discoverable state. Excessive distance: Due to the limited transmission range of Bluetooth, excessive distance between devices can prevent connection. If the phone Bluetooth and car Bluetooth are too far apart, the Bluetooth device may not be detected, or even if detected, the connection may be unstable. Solution: Bring the phone Bluetooth as close as possible to the car Bluetooth. Changed Bluetooth name: If the Bluetooth name has been changed, previously saved devices under the old name will not connect. Solution: Reconnect the new Bluetooth device on the other device. Hardware issues: If none of the above scenarios apply, hardware issues may be the cause. Solution: Visit a 4S store for a warranty claim.
