VW MOST150 Optical Audio Interface

The Valse MOST150 Optical Audio Interface is a pre-amp solution for many Mercedes, Volvo, Skoda, and VW vehicles. This unit is used by Nick, the owner of ResoNix, in his personal vehicle with excellent results (2019 Volvo S60). This allows you to bypass the OEM amplifier and get SPDIF signal converted from the original MOST150 optical signal. This retains audio, blinkers, chimes, and all sensors without issue as well. This is the best solution to getting audio signal when doing a sound system in an applicable vehicle. 

Designed for cars:
. VW Tiguan (2017-2020), VW Teramont (2016-2020)
. Skoda Kodiaq (2016-2020), Skoda Octavia (2016-2020)

. Volvo (tested on S60, S90, XC90, XC60 and XC40 2018-2021)

. Mercedes Benz (2015-2020) with 5th generation NTG head units

Key Notes
& Product Specifications

I have been using this in my personal car (2019 Volvo S60 R-Design with Harman Kardon), and in another local friend’s car (2020 Volvo S90 R Design with B&W) with so far, ZERO issues. This has been the most trouble-free audio interface that I have used to date. If you have any questions regarding this interface, feel free to contact us anytime. Thanks!
