Metra 40-TY12 Antenna Adapter for 2022-2025 Toyota

Metra 40-TY12 Antenna Adapter for 2022-2025 Toyota

Vehicle-specific antenna adapter cable engineered for 2022-2025 Toyota models, connecting the factory antenna cable to an aftermarket radio via a male Motorola connector for clean, plug-and-play AM/FM signal retention during a head unit upgrade.

Product Overview

The Metra 40-TY12 is a vehicle-specific antenna adapter designed for use when replacing the factory radio in late-model Toyota vehicles with an aftermarket head unit. The factory antenna cable in these Toyota models terminates in a Toyota-specific connector that does not mate directly with the standard male Motorola DIN input used by most aftermarket radios. The 40-TY12 bridges this gap, featuring a male Motorola connector on one end to plug into the aftermarket radio and a female Toyota-style antenna connector on the other to accept the vehicle's factory antenna cable.

A blue antenna turn-on lead is attached to the adapter and connects to the antenna turn-on wire on the aftermarket radio, ensuring the factory antenna amplifier activates correctly when the radio is in use. Compatible with a range of current-generation Toyota models including the Corolla E210, Kluger XU70, LandCruiser 300 Series, LandCruiser Prado 250 Series, RAV4 XA50, and Tundra 3rd Gen. Always verify your specific vehicle's application before purchasing.

Frequently Asked Questions

What is the difference between the Metra 40-TY12 and 40-TY22?

Both adapters serve different scenarios. The 40-TY12 is used when replacing the factory radio with an aftermarket head unit — it connects the vehicle's factory Toyota antenna cable to the male Motorola DIN antenna input on the aftermarket radio. The 40-TY22 is used when adding an aftermarket antenna while retaining the factory radio, featuring a female Motorola output instead. Confirm which scenario applies to your installation before purchasing.

Why do I need an antenna adapter when installing an aftermarket head unit?

Late-model Toyota vehicles use a factory-specific antenna connector that does not physically mate with the standard male Motorola DIN antenna input on aftermarket head units. Without the 40-TY12, the factory antenna cable cannot connect to the aftermarket radio and AM/FM reception will be lost entirely. The adapter resolves this with a clean plug-and-play connection.

What does the blue wire on the 40-TY12 do?

The blue wire is an antenna turn-on lead. It connects to the antenna turn-on wire on the aftermarket head unit and signals the factory antenna amplifier to activate whenever the radio is switched on. Without this connection, the antenna amplifier may not engage, resulting in poor or no radio reception even with the adapter correctly fitted.

Is the 40-TY12 compatible with my Toyota model?

The 40-TY12 covers the Toyota Corolla E210 (2023-2025), Kluger XU70 (2023-2025), LandCruiser 300 Series (2021-2024), LandCruiser Prado 250 Series (2024-2025), RAV4 XA50 (2023-2025), and Tundra 3rd Gen (2021-2025). Always confirm your vehicle's build year and model variant against the application guide before purchasing.

Do I need any other adapters or accessories for a complete head unit installation?

The 40-TY12 covers the antenna connection only. A complete aftermarket head unit installation for these Toyota models will also typically require a vehicle-specific wiring harness, steering wheel control interface, and may require a reverse camera retention harness depending on factory equipment. We recommend consulting a qualified car audio installer to identify all required accessories for your specific vehicle.
