A separate antenna belongs to the telephone. This antenna contains a telephone antenna and, for vehicles prepared for Volvo On Call, a GPS-antenna as well.

The phone antenna is directly connected to the phone module (PHM).

For vehicles equipped with Volvo On Call-functionality, the GPS-antenna is directly connected to Phone Module (PHM). This is due to the GPS-position not being available from other control modules in the vehicle.

The antenna is installed on the roof.

Telephone and GPS-antennas can be diagnosed.
