Going back to where I started is not as easy as it sounds. Per the Seicane instructions I cut off both connectors that went into the back of the nav unit. I'm about 95% sure the wires are in the right slots for the blue connector. The other connector has three black wires, all the same, so I don't know what black wire they should be connected to. I completed the first try this evening. The nav unit comes on but nothing is on the screen. There are 5 more ways the wires could go.

I asked for clarification from Seicane for their fix. The response made no sense. They are saying the previous instructions were representative not exact. Said what wires shouldn't be connected and didn't say what wires should be connected or to where.
