MAIN FEATURES
Harness Extension Kit to retrofit vehicles with an OEM Mercedes Audio Gateway to a universal aftermarket head unit.
Allows you to relocate the connector of the factory fitted head unit (Audio Gateway) from the rear of the vehicle back into the dashboard where the aftermarket radio will be located.
The complete pinning of the Extension Harness including CAN-Bus and the antenna remote wire makes it easy to retrofit the head unit by using the original steering wheel remote control functions (if OEM equipped).
Retention of the OEM subwoofers (if OEM equipped) can be achieved. You can either wire the white cables for the sub-woofer to be piggy-backed into the rear speaker channels or you can fit a new amplifier to power just the subwoofer by itself. The recommendation is to fit a new amplifier for the sub and with this in mind, the wiring has prepared RCA and amplifier remote cables into the loom for simple transfer.
