This is a Motorola BTUM Module, part number 84 11 0 410 144. It was designed to fit in the factory v60 phone integration cradle and allow the factory phone system to be used via a Bluetooth connection.
This is an unused adapter, though it was verified to power up and allow a phone to pair to it. The Bluetooth Passkey is included.
From searching on the internet, this Bluetooth Puck may also work on other factory v60 phone systems - like those in Mercedes, Audi, or Jaguar vehicles, but I cannot verify that claim.
I have a mobile electronics installation business and use my Bonanza booth to sell off excess inventory. Please feel free to send a message if you have further questions about any of my items or a question about a handsfree adapter harness for your specific vehicle, many of which are available in my booth.
Thanks for looking!
