I recently ordered the navtool 2.0... with a Boyo VTK350 backup cam..

I already have an isimple connected on the cabin..

the NavTool user guide says that i have to install the Navtool in the trunk which is plug and play.. not big deal.. just uninstall dvd-rom unit plug the cable and reinstall it.. but my question is about the wiring..

The seller told that it is just plug and play but.. reading the instruction i can tell that he mention Black, Orange, Yellow, Red and Grey wires.. but my question is... after i plug the navtool on to the unit.. what i have to do with the wiring colors cables??

My question comes after i read this post:

DIY: Backup Camera with Dom's TVandNav2Go PNP Install

 

It should come with a wiring diagram, either in a paper manual or a sticker attached to the side.
Red and black are power and ground. The others will connect to either ground (grey) or the camera.
If you plan to use the secondary input for anything, you'll need to extend the switch wires to the cabin.
