Introduction: The Car, This Black Box on Wheels
Modern cars are no longer just means of transportation. They have become true computers on wheels, equipped with sensors that continuously collect data. This data includes your location, speed, fuel level, and much more. For many, this raises critical questions about security and privacy. So, how do you protect this sensitive data? For my part, I decided to remove the modem and GPS from my 2024 RAV4 Hybrid. Here's why and how.
Why Remove the Modem and GPS?
Privacy Risks
Car manufacturers collect data that can be shared with third parties, including insurers or data brokers like LexisNexis. In 2025, Subaru faced vulnerabilities that allowed remote unlocking of cars and access to real-time GPS history. Tesla had similar issues, with employees sharing videos of customers.
Data Security
In 2015, hackers took full control of a Jeep Cherokee. These incidents show that sometimes onboard technology increases risks rather than reducing them. By removing the modem and GPS, we minimize these risks.
How to Remove the Modem and GPS
Impact on Car Functionality
Removing the modem and GPS can affect certain functionalities, such as OTA updates and cloud services. However, the car remains fully functional for daily driving.
Removal Steps
- Identify the DCM (Data Communication Module): In the RAV4, it is usually located behind the dashboard.
- Remove the DCM: Carefully disconnect the cables to avoid damaging other systems.
- Remove the Built-in GPS: It may be necessary to disassemble parts of the dashboard to access the GPS antenna.
Conclusion: A Personal Choice
Ultimately, removing the modem and GPS is a personal choice motivated by the desire to protect personal data. It requires a certain level of technical expertise, but it is a step that can bring significant peace of mind.
