I bought this radio with intentions of putting it in my BMW x5 but I sold the car. 

Its a non-branded android radio made to fit BMW 5 E39 E53 X5
It comes with a bunch of connectors and an external mic. 

This unit has navigation and I believe it is 4G compatible if you want to put a sim card in it and use the internet wherever you drive.( cant confirm but there is a connector for a 4g antenna on the back of the unit. Came with limited instructions. The second photo shows the features from the site I got it from. 

Paid $350 selling for $250 - spring cleaning. Box is open but its never been used.

Feel free to reach out with any questions
