Hi there, The SGW is located behind the radio screen. The radio is held in place by screws behind the gear selector buttons which you press down firmly to release them. After removing the screws there are 4 clips holding the radio in place (tough to unclip). Unfortunately it is not equipped with the same 12 and 8 pin connectors as you would normally find. 670222587 is the SGW part number. I am currently in the same position needing to reset the service interval. I can not seem to find a bypass for that specific unit.
