Many modern rental cars offer sophisticated “infotainment” systems that can link up to your smartphone via Bluetooth, allowing you to make hands-free calls, stream your music through the vehicle’s speakers and use your favorite map app for navigation. But these systems can pose a security risk by storing your personal data, including contacts, call logs, text messages and the places you visit during your rental.
“Unless you delete that data before you return the car, other people may view it, including future renters and rental car employees or even hackers,” cautions the Federal Trade Commission (FTC).
So how can you enjoy the convenience of your car’s infotainment system without compromising your security? Collin Ikim of Magrenta, a Romanian car rental company, says he always shows clients how to wipe their data from the system before returning their vehicles. “Most people return [their] rental car at the last moment, when they’re already in a hurry,” he says. “You should give yourself time to remove the personal data stored in the car. It’s a matter of minutes.”
Ikim recommends going into the settings menu of the infotainment system. “There you’ll find a list of devices that have been paired: locate yours and follow the prompts to delete it. If you used the car’s navigation system, clear your location history.”
If all you need is to charge your phone, both Ikim and the FTC recommend using an adapter to power the device via the car’s cigarette lighter rather than connecting via USB to the infotainment system, which might capture your data automatically.
If you do decide to use the system, you can usually choose which data you want to share. Keep your permissions as limited as possible to avoid putting information unnecessarily at risk.
For those renting a car in their own local area, Ikim offers one final suggestion: “Consider setting your home address to a nearby intersection. If strangers get … access to your car, they won’t know the precise directions to your specific home address.”
