About the Crux CS-AXMO Auxiliary Input Adapter for MOST Systems

Done with discs? Add an aux input adapter to your factory radio

Crux's CS-AXMO adapter lets you add an auxiliary audio input to the factory radio of select 2003-2016 Audi, BMW, Mercedes-Benz, and Porsche models featuring the fiber optic MOST audio system. If you've moved on from CDs to media players or other similar devices, this is a great way to listen to your favorite music without changing out the radio entirely. In most cases (except for Audi radios), you'll need to remove the factory CD changer to incorporate the aux input. Audi owners can keep the factory CD changer, or one of the factory CD changers if they have more than one installed.

Done with discs? Add an aux input adapter to your factory radio

Crux's CS-AXMO adapter lets you add an auxiliary audio input to the factory radio of select 2003-2016 Audi, BMW, Mercedes-Benz, and Porsche models featuring the fiber optic MOST audio system. If you've moved on from CDs to media players or other similar devices, this is a great way to listen to your favorite music without changing out the radio entirely. In most cases (except for Audi radios), you'll need to remove the factory CD changer to incorporate the aux input. Audi owners can keep the factory CD changer, or one of the factory CD changers if they have more than one installed.

Use your phone or other device as a wired source

Crux's kit includes a wiring harness and a small black box containing the stereo auxiliary input with 2 RCA jacks. For most installations, you'll just need to swap out the factory CD changer for the black box and replace the factory MOST wiring connection with the included harness. The CS-AXMO emulates the factory CD changer, so you'll be able to hear the audio through the aux input by using "CD-1" as the source on your radio's touchscreen. Audi owners with the factory CD changer still installed can use "CD-7" as the source to hear the aux input audio.

Note: This adapter only works in vehicles with fiber optic MOST audio systems. Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this interface is compatible with your vehicle.
