• Please check your connector before ordering. This bypass is for older (~1998-2003) “Domestic Digital Bus” (D2B) components ONLY (see photos). For newer Mercedes vehicles please check out our other listing for universal “Media Oriented System Transport” (MOST) protocol fiber-optic bypass loops.
• Use our D2B fiber-optic bypass loop to bypass Mercedes’ fiber-optic components to easily troubleshoot bad components or for removal of a component from the optical network.
• Easily remove / bypass your glove compartment CD changer to free up valuable space in your glove compartment!
• Proudly made AND supported in the USA! We are here to help you diagnose your vehicle.  Covered by our LIFETIME Warranty Replacement Guarantee.
• OEM style sealed connection guarantees durability & longevity.
  

  Mercedes – Checking Vehicle Compatibility:

  Mercedes: Our fiber optic loop is compatible with most Mercedes models from 1998-2003. 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 .

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.

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
