Antenna Connectors 7 and 8
1 Transparent color connection for antenna output signal FM from antenna selection control module
2 Brown connector for antenna output signal FM to antenna selection control module (diversity)
Antenna signal input via connection 1 is tested in radio and result is output via connection 2 to antenna selection control module. Function is switched to another antenna when antenna signal is determined to be weak (diversity). This procedure is not audible to the customer.
