Don’t connect to rental cars

If you hire vehicles when traveling — for leisure or business — avoid using the connectivity features in the car. Whether it’s Bluetooth for your phone or music, or synced GPS maps, you’re opening up your personal device to exchange data with an unknown entity that has been used by an unknown number of strangers. If you want to use your own device for music or navigation while driving, invest in a standard AUX lead and a removable phone mount so you can keep your phone functional, but safe.
