"Mystery" MOST Component
MY 2007 XC90
Does anyone know what the function of this component is, found in the rear cargo area near the REM? It appears to be a just loop of fibre optic cable, protected by enclosing it within a fibrous matting pouch. My supposition is that it is exactly that, a terminator for the MOST network. If that is so, is it the point of connection for a sub-woofer module? ie. just unplug the terminating loop and plug-in the Subwoofer input? TIA |

The function of that fiber "loop" is simply to bridge-out the non-fitted optional device at that location, which is the subwoofer
The MOST ring is a uni-directional fiber ring When the car is built, the fiber is laid out for all optional devices where necessary Example: the fiber runs to the sub location If the sub is not fitted, then a "bridge" must be fitted to bridge the fibers together and ensure the fiber ring is intact What you see is the fiber "bridge" - it brides the fiber together to keep the ring intact When fitted a sub, you remove the fiber bridge.
