Removing the modem and GPS from a 2024 RAV4 hybrid

Arkadiy removed the modem and GPS from his 2024 RAV4 hybrid, cutting the vehicle’s cellular and location tracking capabilities at the hardware level [Arkadiy's Blog]. He disconnected the telematics control unit (TCU), located in the trunk, and the GPS antenna, typically mounted on the rear windshield. Both components are factory-installed for Toyota’s connected services, including emergency assistance, remote diagnostics, and navigation.

The TCU in the 2024 RAV4 runs on a Qualcomm MDM9615 chipset and connects via AT&T’s network in the U.S. [Arkadiy's Blog]. By physically removing it, Arkadiy eliminated the car’s ability to report location, speed, or system status to Toyota or third parties. The GPS antenna, a small patch unit wired to the TCU, was unhooked to prevent passive signal leakage.

This mod bypasses software limitations and disables data collection at the source. Unlike toggling privacy settings in the infotainment system, which may not fully halt transmission, hardware removal ensures no remote reactivation. The car continues to operate normally—hybrid powertrain, safety systems, and climate controls are unaffected.

Why it matters:

• Some 2024 Toyota models collect up to 1.5 GB of data per month, including trip logs and driving behavior [Arkadiy's Blog].
• The TCU retains data even after factory resets, making physical removal the only guaranteed way to stop transmission.
• Independent repair shops and privacy-focused owners are increasingly modifying embedded vehicle systems, challenging automakers’ control over hardware access.

No software update can restore connectivity without reinstalling the hardware. Arkadiy’s work shows that direct intervention is possible—and effective—for users seeking full control over their vehicle’s data footprint.
