Scott Posted November 9, 2016 Report Share Posted November 9, 2016 The bottom PCB (the bigger board) should have a version number printed on it. Select the base-map to match the version you have.Changes that I can see are to do with the Air Conditioning switch inputs and also some additional engine fan outputs.Scott Quote Link to comment Share on other sites More sharing options...
