I have MB Bluetooth pucks B67876131 ($170) and B67875878 ($120) for sale. All prices include shipping within CONUS and PP fees. I prefer local sale in San Gabriel CA, and if so, knock off $10 from listed price. These are newer than the model ending with "839", but make sure the model will work with your vehicle before purchasing.

I will replace any DOA pucks upon receiving the original unit back.

I have excellent feedback on Ebay and Calguns.net under the same handle. As evidenced, I don't frequent this forum much since my wife's MB was sold a while back. Please IM me if interested or for pics (provide your number or email so I can send from my phone).

All units are sold. Thank you MBWorld.
