$20 · Mercedes Bluetooth Stereo Adapter

***I am super unclear why people keep thinking that this is a Bluetooth stereo adapter. It very-much not. This is the hardwire adapter to run iPhones or iPods in your Mercedes. ~TO BE REALLY CLEAR~ To use this will Lightning port devices; you would need to add the 30-pin to Lightning adapter, which if I can find mine; I will include it. As pictured. Not entirely sure which models in works in. We had 2010 era ML350 Works great. I imagine that it works in many MB models. Thanks! *It is Mercedes audio port connection to Bluetooth.
