AUDI SAMSUNG PHONE ADAPTER

[curlylad]

Just purchased a used Audi TT with a mobile phone mounting unit on the dashboard.
I need to get an adapter for my Samsung phone, anyone know if I have to buy direct from Audi or do other companies make an alternative ?

Many thanks in advance.

Here's the mounting...is this an original Audi type and can I get a Samsung adapter for this ?
