I try to hook up a Bluetooth to the radio system and somehow the wires get short and some of the radio pulse was blow , I replace the pulse everything the radio working but the navigation still not display .. I check the navigation unit under the seat and still hear cd spinning but no navigation display at all .. I check all the pulse but still not work .. pls help

 

try ejecting the nav disc then put it back in are you sure you connected everything back. if there is a short, need to locate it and repair it. how did you short it out???? was the truck on? were you tapping into something????

 

I was hot some of the wires to find out which one is power etc that what make it short .. I will try to eject the disc and put it back hope it will work .. I willl let you know if it will work again .. thank for your time

 

Well, what happened? Not being a D*%^ but they have wiring diagrams available here and other places if you look.
