I am curious if anyone has any experience installing the Clarion NAX980HD Navigation unit? I need to know where the speed sensor wire is to tap into. Can I use the speed wire from the factory wire harness? It also has a reverse sensor wire, can this be the back-up light wire? I am putting this into a 2004 F150 Supercrew and am mating it up to a Max685BT.

 

What vehicle do you drive?

Reverse = Back up light.

 

This is going into a 2004 Supercrew.
