connecting an external amplifier
USB: a rear USB port (REAR USB)

DAB antenna: an SMB connector with 12 V phantom
power (max. 150 mA, switchable in the menu, see

FM/AM Antenna: a DIN connection
Terminal block with section A (power supply), section

MUTE: mutes the car radio by contacting ground
BATT (cl. 30): the battery

power supply for active antennas or control voltage for
external power amplifiers/subwoofers (12 V, max. 150 mA)
DIMMER/LIGHTING (cl. 58): the vehicle lighting input,
required for automatic button/display brightness switching.
The input requires 0 V/12 V. PWM signals may cause the
display to flicker and must not be used.

Tip: the car radio does not support CD changers,

pole correctly, otherwise the car radio will consume
increased current and will not shut down completely, which
can discharge the car battery!
