Available on backorder
In the world of modern car audio, integrating into the OEM sound system is one of the most prominent challenges that we face in nearly any installation. Our ResoNix EZ B-M25 Interface seamlessly converts the MOST25 signal that is used in 2010-2019 BMW sound systems that feature the Harmon Kardon OEM sound system trim, into a usable digital output. It features an S/PDIF toslink output AND coaxial output to allow you to have a clean digital signal that features none of the OEM processing for an easy, straightforward, and clean sounding car audio system design and installation. This is much preferred over having to do high-level signal integration, which will have you battling distortion, bass roll-off, equalization, crossovers, all pass filters, upmixers, limiters, variable volume equalization, and more.Â
    The ResoNix EZ Interfaces retain all OEM features, including backup sensors, door chimes, navigation prompts, Bluetooth calls, and more, unless specific otherwise. Please note that SOS systems are usually separate from the audio system and are left alone.Â
We strive to bring you the cutting edge in automotive technology.Â
Works with any BMW that is equipt with the a MOST25 Fiber Optic system from the factory head unit to factory amplifier. Usually, these are the OEM Harmon Kardon systems. If you need help determining if this is right for your vehicle, feel free to reach out any time.
Please note, this does NOT have RCA outputs. It only features S/PDIF digital output via toslink and coaxial, and must be used with a Digital Signal Processor that features a digital input.
