I have been trying to gat all the doors to unlock as well so will try all the suggestions but may it seems be a dealer only fix, the windows opening on one touch would be good as well ,My Landrover does all this straight out of the box I'm astounded that its so difficult for Subaru !!
Oh and I'm also amazed at the size of the manual that's seems to tell you very little - maybe get a UK based technical authour !!
