Brand: BMW OEM GENUINE E46 3 Series SAT NAV MK3 MK4 bracket Racks Holder GPS Wiring BMW Navigator IV | Adventure Rider The docking unit with my BMW Navigator IV does not include documentation for the wiring / connectors. I have emailed Garmin, but they say this is a BMW product and they can not help me. I am trying to connect it to my 2007 BMW F650 Dakar. The harness that came in with the unit was the older Navigator III. Anyone have a schematic or documentation?
