Wireless convenience can open brief windows for attackers to exploit a nearby connection, using tactics known as bluebugging or bluesnarfing. Simple adjustments to your phone and car settings cut that exposure substantially.
Switch off Bluetooth and hide your device
Turning Bluetooth off when you’re not using it is the most direct defense. It shortens the time your device is visible to others and reduces the chance of a nearby attacker establishing a connection.

When you do keep Bluetooth active, set it to hidden rather than discoverable. Hidden mode prevents unknown devices from seeing your phone, making unsolicited pairing attempts less likely.
Unpair and erase data before you hand over a vehicle
If you connect your phone to a rental car, or plan to sell or return a vehicle, remember to unpair your phone and remove any personal information stored in the infotainment system. Failing to do so can leave contacts, call logs or navigation history accessible to the next driver.
Also note that wireless Android Auto uses both Bluetooth and Wi‑Fi, which creates additional connection points an attacker could target. That combination increases the surface for potential intrusions compared with a wired connection.
To avoid automatic wireless connections, you can disable the feature inside your phone by setting “Start Android Auto Automatically“ to Never. That prevents your phone from initiating a wireless link without your explicit action.
Watch the iPhone Live Listen setting
On iPhones, the Live Listen feature streams audio from the phone’s microphone to AirPods, hearing aids, or compatible headphones. Because it operates over Bluetooth, it can create an extra avenue for the same sorts of attacks.
To be safe, check Accessibility settings and turn off Live Listen if you do not need it. That removes another potential Bluetooth-enabled entry point into your device.
