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 🙂

    The one that fits!

    The only one that fits. I bought one of the others that comes with a male and female connector, but the connector did not fit my BMW (e64). This loop fit perfectly.I was able to determine that the XM module was not functioning and was the “burned out bulb in the line of Christmas tree lights”. Because of the faulty XM module, the amplifier was not working. There were no sounds from anything, not even the back up sensor. I disconnected the fiber optic cable from the XM module and plugged in this loop, thus bypassing the XM module and everything else came back to life. I will keep the loop in place until I replace the XM tuner.

    Great Service

    Fits fine and if my battery stays up for the next week, I’ll know that it worked.

    This solved the SOS light on the dash and fixed the popping noise coming from the speakers. I installed it on the satellite module and all the problems instantly stopped. Highly recommend!

    Excellent Product and Customer Service

    I received the dreaded SOS error on my 2007 BMW after which I had no sound for 3 months. After doing some research I learned that it was likely to be the XM radio loop. I purchased the product to bypass it. Unfortunately, during that install I had difficulty locating the amp. However, I used the QR code on the package to locate a chat to have customer service support me with locating it. They sent over labeled pics! I now have sound and was able to save about 1200 bucks! Don’t hesitate to buy this product or lean on customer service for support!

    Saved my $1900.00

    This worked perfectly. Mercedes was going to charge $1895.00 to replace the module located behind the glovebox. After an hour of work we had sound. I highly recommend it!!!

    Tried the cheaper ones first...

    But ended up getting this one because it just fits, without needing to be trimmed or fiddled with.
