Metra Axxess AXM50-GM1 MOST50 Bose Amplifier Retention Interface

Keep the factory Bose amplifier when replacing the radio in a compatible GM vehicle. The Metra Axxess AXM50-GM1 connects an aftermarket radio to the vehicle's MOST50 amplifier system and preserves left/right balance control.

Features

• Factory Bose amplifier retention for select GM applications
• Left/right balance control retained
• Firmware updates through a Micro-B USB connection
• Manufacturer's 1-year limited warranty

Silverado and Sierra compatibility

For Bose-equipped vehicles with a compatible MOST50 system and factory radio RPO code IO3, IO4, IO5 or IO6:

• Chevrolet Silverado: 2014-2018
• GMC Sierra: 2014-2018
• GMC Sierra 2500/3500: 2015-2018

Check the exact vehicle, factory radio RPO code and replacement radio before ordering. Bose branding alone does not establish compatibility. Metra's current product sheet does not list 2019 Silverado or Sierra applications.

Installation notes

This is an add-on amplifier interface, not a complete radio-installation kit. Additional radio integration parts may be needed. Metra recommends a compatible additional interface for easier plug-in installation. Factory rear-seat entertainment is not retained by this interface. Follow the manufacturer instructions for the vehicle's CD/DVD-drive jumper connections.

Included

MOST50 interface, T-harness, jumper harness, MOST universal harness and MOST2 adapter harness.
