Antenna Systems, RCD 300, 500 RNS 300 and Premium 7

General Information

Antenna System.

• Vehicles without radio have no rear window antenna and a "dummy" antenna without any connections is installed on the roof.
• "RCD 300", "RCD 310" and "RCD 500" radios have a rear window antenna with a right antenna amplifier as well as a roof antenna with antenna mast. One diversity function circuit runs via the rear window antenna, the second via the roof antenna.
• If the vehicle is equipped with a radio and also telephone equipment or auxiliary heating remote control, antenna system has rear window antenna with 2 trap circuits and diversity as well as a roof antenna.
• The "RNS 300" radio navigation system has a rear window antenna with a right antenna amplifier and a roof antenna.
• Vehicles with "RNS 510" radio/navigation system always have a rear window antenna with 2 trap circuits and diversity and a roof antenna, regardless of additional equipment.

Note

• Familiarity with the function and operation of the communication systems is needed if there are customer concerns.
• Refer to the Owner's Manual.
• When the battery is reconnected, check any affected system or component (radio, clock, comfort electrical connection etc.) according to the repair manual and/or the Owner's Manual.
