Well, with the gps plugged directly into the back of the empeg it works fine. So im guessing the problem is that the sled plug has pins 2 and 3 swapped. Instead of getting a new adapter or making one myself, would it be possible to just switch the connections on the docking connector itself? I know its possible to pull the little metal connectors out and put them back in. I even remember seeing a video about it on here somewhere (i think it was Mark Lord that made this?). Could I just swap the 2 wires on the connector? Would this work?
