Hi,

hope somebody can help as I've googled but can't find the answer.

I have a 2013 Cooper D Convertible that half the buttons on the radio have stopped working on. Removed to replace with after market model and can't find out what three of the existing cables that are connected are.


The black one is the radio aerial which I've connected and works but don't know what the green. yellow and white ones are - anybody know please?

And was going to place the gps receiver for the after market radio on dash and run wire through to new head unit and have found this small covered circuit on the dash:

again - anybody know what this is please?

Hoping somebody can point me in the right direction for both questions :-)
