GMOS-05
INSTALLATION INSTRUCTIONS
The GMOS-05 is designed to be used in Onstar equipped vehicles
with the “Dock and Lock” style harness, the radio harness that
stays mounted in the dash when the radio is removed. The radio
itself is held in by two spring loaded clips, one on each side.
Besides retaining Onstar, the GMOS-05 retains the warning chimes
that will be lost when the factory radio is removed. The GMOS-05
will also provide a 12 volt switched accessory wire for proper radio
operation.
*Note:
This interface will also work in vehicles listed below that are
not equipped with Onstar
