2. Hardware Installation
The ADS-MSR module requires a vehicle-specific T-Harness (sold separately) for plug-and-play integration. This harness simplifies the wiring process by connecting directly to the vehicle's factory wiring and the aftermarket radio.

Operating Instructions
1. Radio Compatibility
The Maestro ADS-MSR is compatible with a wide range of aftermarket radios. For non-Maestro compatible radios, it connects via a standard steering wheel interface cable. For Maestro-compatible radios (from brands like Kenwood, JVC, Alpine, SONY, Pioneer), it utilizes a 4-pin serial connection for enhanced integration and features.
2. Retaining Vehicle Settings
The ADS-MSR module ensures that crucial factory vehicle settings are retained and accessible through your new aftermarket radio's touchscreen. These settings can include lighting control, door lock options, camera settings, driving modes, instrument cluster displays, parking assistance, collision avoidance systems, and TPMS settings. If using a non-Maestro compatible radio, these settings can often be accessed and controlled via the iDatalink Weblink Mobile app on your smartphone.
3. Camera Integration
The Maestro ADS-MSR retains factory reverse cameras, 360-degree cameras, and cargo cameras. It supports factory multiple viewing angles or split-screen views for reverse and 360-degree cameras, controllable via a steering wheel button. Additional accessories may be required to fully integrate the backup camera. The system works with most aftermarket radios.

4. Programmable Outputs
The ADS-MSR features two programmable outputs that can be configured to control aftermarket accessories added to the vehicle. These outputs can be set to Latch, Toggle, or follow a CAN signal (firmware dependent). You can also configure Delay On and Delay Off times for each output and assign a steering wheel control button to control them.
