hi all, new user here.ive got a sat nav unit from an 04 prado grande that i want to put in my 04 100 series gxl. i'm guessing the connections are the same by the looks of things but there are two single wires in the harness which i have no idea where they go, white wire and brown or green(cant quite tell).does anyone have a wiring diagram of the unit? any help will be much appreciated. cheers.
