I was gonna let my friend install a new touch screen on my car but he was taking it out he messed up the wires an they fell out of the plastic piece took it to a shop an they told me they would have rewire the whole car an would take about 4 hours I do have the boss an nav do I really have to rewire the whole car or I just buy a new wiring for those to pieces? Or like a new wiring harness or somthing idk I'm lost. Thanks for the help

 

Didnt you post this exact same thing a couple days ago?

 

No, that was his twin brother.

 

Yes, but I posted it in the wrong thing.

 

You don't have to rewire the whole car. They were just trying to bank off you.
