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 🙂

    Excellent customer service!

    I gotta tell you I have not received customer service from anyone in a long time. Product worked as described and was perfect for my satellite radio.Upon having some issues troubleshooting they helped me through with quick response time. I would fully recommend this vendor. He went twice the extra mile and was willing to look up parts for me online if I needed any. Thank you very much.

    Great product. Trustworthy seller

    Had audio issue with my bmw e92 and they helped get to the bottom of it. Either the product plug and play solves your issue. Or you reach out to seller and they will assist you further. Not too many sellers willing to go that extra mile!

    Even came with the zip tie.

    Hardest part was taking the trunk apart. Great product, I paid more and so should you. No cutting of the most connector and having it fit right in and then having the correct zip tie. Nice. Plugged it in and sound came right back. Ty

    Easy Fix

    I used this for bypassing Sirius module on BMW E60 that had gone bad causing an SOS light and radio rebooting. Perfect for troubleshooting MOST systems.
