Description:

I have TWO Bovee Tune2Air Bluetooth devices to sell; "WMA3000A". I sold GLK, so selling these. One is brand new still in the box, the other has been used for about 3 years 35,000 miles. It has lived in the center console doing its job drama free. This is truly a set and forget item, unlike many of the 'solutions' out there. You plug it into the MMI plug, and forget about it. It powers on and off by itself with the vehicle, will connect with your phone automatically each time.

I have two because if one happened to break I wanted to have another in case they went out of production. This was used with 2012 GLK with MMI connector. I would expect C class to be similar. In the 2012-ish vehicles your phone could use Bluetooth but it isn't able to stream music or interact with your music library through the car. This device seamlessly integrates your phone, music, music library, and calls into the vehicle just as you would expect from the factory directly through the stock interface.

Selling each one separately.

the one that is NIB $75
the one that is used $65
