■ Install the car kit in a vehicle
This section describes how to install the car kit parts in a vehicle. The 
parts are explained in “Parts”, p. 11.
When installing the parts of the car kit, ensure that none of them 
interfere with or hinder the steering or braking systems or other controls 
or systems used in the operation of the vehicle (for example, airbags). Do 
not use screws to install the display if you mount it within the head 
impact area. Use the supplied adhesive instead.
Installation of the car kit may cause warning or other alert tones in the 
vehicle (such as reversing warning tones or lights left on alerts) to be 
muted. For further information, contact the manufacturer of the vehicle 
or its representative.
