I'm selling one of my two snap-in adapters, part number: 220.127.116.11.682.
It has been used only once or twice and is in Like New condition. It will come in it's original box w/ the instruction book and packaging material. This was purchased from a BMW dealership.
This adapter has the following features:
1. The ability to charge the phone battery
2. Secure and stable docking system
3. Increases network reception via the car's extrernal aerial
The phone looks fantastic docked and I would never go back to not using one.
Price is $100 shipped within the US.
