I moved from a 2001 to a 2004 gauge and had my "Porsche Zentrum" activate the OBC.
Works as intended. I did all the wiring myself.
As you mentioned all the parameters are shown in the 3rd line.
But this is very interesting, that the display can function in different settings, like yours showing the selected parameter in the 2nd line.
A picture would be nice, to see how that looks.
Does that imply, that it MIGHT be possible to mod the OBC display? I really would like to see the speed in the 3rd line...but that might never happen
