The Metra AXHN-1 Data Interface with Data Signal Turn-on is a vehicle-specific integration module engineered for select Honda vehicles from 2012 to 2014. This interface supplies the required data-based turn-on signal and accessory power needed when installing an aftermarket head unit in vehicles that do not provide a traditional ignition or remote turn-on lead. It also retains important factory features such as clock setting, balance and fade control, and the OEM AUX input. Designed for professional installers, the AXHN-1 ensures a clean and reliable OEM-to-aftermarket radio integration.
