PRODUCT INFORMATION
CTSBM017.2
The CTSBM017.2 aids the installation of an aftermarket stereo into an OEM dashboard. It helps retain
steering wheel control presets as well as retaining vital features and functions which include parking
sensor audio and phone button functionality (if applicable). Our interface also allows for the retention of the
original head unit for the purpose of retaining key vehicle settings menus via the original display.
Please note: this product is for non-amplied vehicles only. Although the interface works to retain most settings,
some will remain “grey”. For these settings, the use of a MOST extension harness is needed (sold separately).
