iDatalink Maestro HRN-SR-GM2 Interface Harness

iDatalink's HRN-SR-GM2 wiring adapter works in conjunction with iDatalink's Maestro ADS-MSR module, allowing you to connect a new car stereo in select 2010-up GM vehicles. Once connected, you'll retain the use of your steering wheel audio controls and factory amp in these vehicles. The package includes connectors that plug in between the Maestro module and your factory radio's wiring plugs. You'll keep factory features in select vehicles including warning and park assist chimes (external chime module included) and Retained Accessory Power (RAP). The adapter also provides 12V accessory power, an illumination output, and the parking brake, reverse, Vehicle Speed Sense [VSS) outputs required for navigation-ready receivers. The optional CAM-SR-GM2 adapter (sold separately) allows you retain your vehicle's factory backup camera when used with the iDatalink Maestro SR interface module and HRN-SR-GM2 installation harness. This harness features an in-line head-unit connector harness, which will plug into iDatalink's new "Head-unit direct" harnesses for select radio brands. If you're installing a radio that doesn't work with a "Head-unit direct" harness, you simply cut off the plug and connect the wires to the harness included with your new radio.
