The Axxess AXEU-MOST25 is an add-on amplifier interface that keeps the factory Harman Kardon amplifier working when you replace the radio in select 2001-2020 BMW and Mercedes-Benz vehicles with the MOST25 fibre optic audio system. Your new radio plays through the factory amplifier and speakers, and balance control is retained.

Important: this is an add-on

The AXEU-MOST25 does not work on its own. It must be used together with a compatible Axxess radio replacement interface, sold separately. Call us on 647-439-4485 with your vehicle and we'll confirm the right pairing before you order.
