Using the Cosmetic Trim Ring
A cosmetic trim ring is packaged with the
head unit for installation
fexibility. This unit will ft into most import
dashes with little or no
modifcation 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 appropriate
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 30° of horizontal. Make
sure the unit is mounted within this limitation.
