Metra AXUSB-MB USB Retention Harness

USB Retention Harness 12 Inch - Mercedes 2007-2014 Axxess AXUSB-MB is a wiring harness designed to specifically retain the functionality of your factory USB port after installing an aftermarket car stereo in select Mercedes-Benz vehicles from 2007 to 2014. The AXUSB-MB acts as a bridge between your new aftermarket car stereo and your Mercedes-Benz's factory USB port. This allows you to continue using the USB port for its original functionalities, such as Music Playback: Play music files stored on a USB flash drive through your aftermarket stereo, Device Charging: Charge your phone or other compatible devices through the USB port (depending on the port's capabilities). The AXUSB-MB is pre-wired cable with connectors on either end. One end connects to the factory USB port in your Mercedes-Benz, and the other end plugs into a designated USB input on your aftermarket car stereo. This simplifies installation by eliminating the need for manual wire splicing. The Axxess AXUSB-MB is a convenient solution for Mercedes-Benz owners upgrading their car stereo with an aftermarket model while maintaining the functionality of the factory USB port.
