"CONCERN
ONLY WHEN REVERSE IS SELECTED, THE MAIN VOLUME CONTROL
KNOB / RADIO POWER BUTTON NEAR THE SHIFTER, DOES
NOT OPERATE. RADIO AND OR PARK DISTANCE VOLUME CANNOT
BE ADJUSTED FROM THE MAIN VOLUME CONTROL KNOB. ALSO, THE
RADIO POWER BUTTON WILL NOT SWITCH THE RADIO OFF OR ON
WHEN REVERSE IS SELECTED.
CAUSE
CURRENTLY THIS IS THE INTENDED DESIGN OPERATION, WHICH
LIMITS THE CUSTOMER FROM FULLY MUTING OR TURNING OFF THE PARK
DISTANCE VOLUME. VOLUME CONTROL FOR EITHER THE RADIO OR THE
PARK DISTANCE TONES CAN STILL BE ADJUSTED FROM THE STEERING
WHEEL VOLUME CONTROL SWITCHES TO LIMIT THE OR RAISE THE
VOLUME OF EITHER SYSTEM."
