ADS HRN-AR-TO1

The ADS / iDatalink Maestro HRN-AR-TO1 (a-TO1) is a vehicle-specific Amplifier Replacement T-Harness engineered to streamline replacing the factory amplifier with an aftermarket amplifier or digital signal processor (DSP) in select Toyota and Lexus vehicles equipped with premium amplified sound systems (such as factory JBL systems).

Key Features

• Plug-and-Play Amplifier Integration: Plugs directly into the factory amplifier harness connectors, eliminating the need to cut, splice, or run new speaker wiring throughout the vehicle.

• Maestro AR & DSP Compatibility: Engineered to connect factory source units to the iDatalink Maestro AR (ADS-MAR), Maestro AR2 (ADS-MAR2), or Rockford Fosgate DSR1 processor.

• Factory Feature Retention: Retains crucial factory audio settings, system chimes, alerts, navigation voice prompts, hands-free phone calling, and steering wheel audio controls when paired with the compatible DSP/interface module.

• Speaker Line Access: Provides direct access to OEM speaker lines so your aftermarket amplifier can drive the factory speakers without running new wires into the doors.
