When getting to the back of the nav system, I noticed an open blue plug at the top left of the system-(when looking at the rear, upper left)....Does anyone know what this is for? I'm thinking its the plug for satellite radio but if its some kind of other aux input (maybe video?) that would be fantastic.

You can see it to the left of the top row of plugs, partly hidden by a wire coil...Its the dark blue plug, not the light blue one
