Installation
Using the Cosmetic Trim Ring
One cosmetic trim rings is packaged with the head unit for installation flexibility. This unit will fit
into most import dashes with little or no modification to the dash board/cavity. Some US domestic
vehicle dashes will accept a Double-DIN chassis, but there is usually a small gap between the
radio and dash piece after installation is complete. In this case, use the trim ring to conceal any
gaps that may be present.
Note:
For proper operation of the CD/DVD player, the chassis must be mounted within of horizontal.
