Maestro ADS-MRR Radio Replacement Interface
The Maestro ADS-MRR module enables installation of a compatible aftermarket touchscreen receiver in select 2006-up vehicles while retaining steering wheel audio controls and factory amplifiers. It works with a required vehicle-specific harness to integrate all stereo connections. The interface also preserves factory convenience features such as OnStar, SYNC and Uconnect with select Kenwood, Alpine, Pioneer and JVC receivers. Engine performance data can be displayed on the touchscreen with supported multimedia units.
HRN-HRR-CH3 Adapter for Chrysler Vehicles
The included HRN-HRR-CH3 integration adapter extends compatibility to select Chrysler, Dodge and Jeep vehicles from 2013 and up. It connects a Maestro-compatible car stereo to the factory wiring to retain steering wheel controls and the factory amplifier. This adapter is necessary when the ADS-MRR module is installed in those specific Chrysler-group applications. Without it, the interface cannot communicate with the vehicle data bus in those models.
Sustained Operation and Data Integration
Under continuous use the module maintains communication between the aftermarket receiver and the vehicle data bus to keep steering wheel controls, factory amp output and convenience features active. It streams engine performance data to the touchscreen without interruption during long drives. Stable operation depends on a correct vehicle-specific harness connection and a supported receiver. Vehicles outside the listed model years or brands cannot be supported by this interface combination.
