Connectors 7 and 8, antenna connections
1 - Transparent connection for antenna input signal, FM from antenna module
2 - Brown connection for antenna output signal FM to antenna module (diversity, antenna selection)

The antenna signal input from connection 1 is checked in the radio and the result sent via connection 2 to the antenna module. If the antenna signal is too weak, the module then switches to another antenna (diversity). This process is not audible to the customer.
