yeap, this is it...

you see these 4 blank plugs?

the top row of plugs is used for the rear seat heating (i have to get to my other laptop to see if you are pre wired for the rear seat heating).

the bottom row is used in markets other than US, left is for AV input for TV module and the right is for TV switch button... The TV module is useless in the US as we moved to digital signal that is not compatible with the rest of the world but could be useful for the rear camera retrofit...
