I belive the trick is to remove the radio. If its factory take a 2.5 mm allen socket or wrench to the two outside retainers, may have to use a fine flat head srew driver to pop the tabs to gain access to the allens. Once they are loose pull the radio out and lay aside, dont remove any wires unless you have the code in which youll have to call it in with the serial number. You will see a exstended lever to the left of the OBC. Simply pull the arm toward you and the OBC will side out proportioned to the arm. One note is that there is a tie strap that you must cut to release the slack on the harness. Take the flat head again and place it at the connector, behind the black tab. Pry outwards and off she comes. No coding or reseting is required. Just the time, date, year, table [ km / mile ].
