For information on installing or removing your 
radio from a vehicle, refer to the Installation 
Guide.

1 Using your thumb or forefinger, lift up one of the 

corners of the microphone grommet and firmly (but 
gently) pull that corner until the seal comes away 
from the cavity.

Notice  Remove the grommet carefully as it serves 
two important functions. Firstly, it prevents damage to 
the microphone socket due to movement of the 
microphone cord, and secondly, it ensures that the 
control head is sealed against water, dust, and other 
environmental hazards.

2 Repeat to expose another corner.
