Recently purchased a lightly used 2014 GL350 with the Factory Rear Entertainment System but there were no headsets. We verified operation via wired headsets and the system seems to work. We have ordered and received 3 headset pairs based on the factory headset part number but one of the 3 did not have the Left / Center / Right Switch. Not sure what to make of this oddball set???

We are scheduled next week at an Indie shop that has the MB Star Diagnostic System and says he can perform the pairing procedure. My question is whether this odd ball headset will pair and will it pair to the front or one of the rear sides? Any advise is appreciated.
