Universal Fiber Optic Loop Female Bypass Adapter Compatible With BMW, Mercedes & More
Universal Female Bypass Connector
The M&P USA (Mods and Projects) fiber optic loop features a unique, universal, female style connector that ensures proper fitment!
You may have noticed that our bypass loop looks different than other bypass loops out there – That’s because we modified it to universally fit the connector for every component in your vehicle including, but not limited to:
· Satellite receivers
· Power amplifiers
· TCUs (Bluetooth) module
· MULF units
· CD changers
· COM Boxes
· MMI Modules
USA Made, USA Standards!
The M&P USA (Mods and Projects) fiber optic loop is made in the USA and we follow USA standards you can trust.
Please take the time to read some of our reviews. Sometimes, correcting the fault in your vehicle requires additional troubleshooting. If you continue to have problems correcting your audio or SOS light issue after installation of the loop we will work with you to troubleshoot your unique scenario to resolve the problem as quickly and cheaply as possible regardless of the issue.
Compatible with BMW, Mercedes & Many More
Our Fiber Optic Loop is universally compatible with BMW, Mercedes & any other automotive manufacture’s multimedia components that utilize MOST (Media Oriented Systems Transport) technology.
Our fiber optic loops are pre-modified to FIT every multimedia component connecter, every time!
Please scroll down and check the compatibility list below for detailed vehicle compatibility information.
No Gimmicks, No Waste!
When you test or bypass a multimedia component, you ONLY use the “Female” style fiberoptic bypass loop!
Don’t be fooled by “pairs” or “2PC sets” of Male & Female fiber optic loops.
The “Male” loop included in these “sets” is absolutely useless to anyone troubleshooting sound and SOS errors with their vehicle, we promise, it will wind up in a landfill! To make things worse, the “Female” loop in these “sets” often requires modification & cutting by the user to make it fit the plug on your multimedia component.
Our Universal Female Fiber Optic Loop fits every time. No Frustration, No Waste!
BMW – Checking Vehicle Compatibility:
BMW: Our fiber optic loop is compatible with all BMW models from 2006-2011. (keep reading below for newer models) In BMWs, components with fiber-optic connections are identified by their green optical cables. The image on the left shows a typical component layout with the male MOST connector cable disconnected from a component. In BMWs, multimedia components are typically located in the trunk near the driver-side tail light, or in the bottom center area underneath the cover panel. Components and locations will vary based on your make, model and vehicle options (we will help you find them as needed).
2012+ BMW models utilize a consolidated communication module (com box) replacing the older, separate components used in previous years. Our fiber optic bypass is compatible for testing purposes, however, 2012+ BMWs will likely require further troubleshooting (we are happy to help).
Mercedes – Checking Vehicle Compatibility:
Mercedes: Our fiber optic loop is compatible with most Mercedes models from 2004-2011. Mercedes vehicles generally have more components connected to the fiber-optic network than BMWs. In Mercedes, components with fiber-optic connections generally can be identified by their orange optical cables.
The image on the left shows a typical Mercedes component layout. In Mercedes, vehicles’ multimedia components are typically located in the trunk near the driver side tail light, or in the bottom center area underneath the carpeting panel. Component locations will vary based on make and model, we will help you find them as needed. Once the component you wish to test is located, our fiber optic bypass will fit .
Other Vehicle Manufacturers – Checking Vehicle Compatibility:
Other Vehicles: Countless other vehicle manufacturers utilize MOST (Media Oriented Systems Transport) technology. To check compatibility simply locate one of the components in the trunk area and look for a fiber-optic cable connection; they are typically either orange or green cables. Once located, disconnect the connector from the component to check and see if it looks like a male MOST connector (reference the two male plug examples in the image on the left). Either style of male optical connectors loop shown in the photo are compatible with our fiber optic loop.
Note: There are additional styles of fiber-optic connectors out there, as long as the spacing and diameter of the two on the connector match, our loop will work. If you’re not sure, you can always order one of our fiber optic bypass units, give it a try, and return it if it does not fit.. We promise, we wont be offended 🙂
Our UNIVERSAL Female Fiber Optic Loop is Plug & Play & fits ALL BMW and Mercedes fiber optic multimedia component connectors. (Other Amazon seller’s standard adapters WILL NOT fit many multimedia components without modification)
