| t
| Vehicles with radio “R100” only have a rear window aerial. |
| t

| t
| If the vehicle is equipped with a radio unit and telephone equipment or auxiliary heater remote control have also been ordered, the rear window aerial with 2 blocking circuits and diversity plus a roof aerial are fitted. |
| t
| Vehicles with radio navigation system “RNS 300” are fitted with the rear window aerial without diversity and with a roof aerial. |
| t

| The aerial system with diversity function optimises and improves reception in the vehicle. |
| The radio unit checks the aerial input signals and puts out the result via an additional aerial connection. The information from the test result then reaches the aerial selection control unit. If the aerial signal being received is too weak, this then switches to a different aerial (diversity). The customer will not be able to perceive this procedure audibly. |
