I am thinking about installing a factory delphi nav into my 2004 yukon, will i have to replace the wiring harness?

if you say it is a oem nav then you should not have to but you will have to buy several addons such as the dvd player for the nav cd the antenna and w/e else you will need to make the factory nav work

I have the d 3 installed in my ride now, i want to replace it with a factory nav.

PLEASE HELP

Theftlock will prevent you from putting in a different factory deck than what the car originally came with.

factory lock can be reset by a dealer. its called "flashing" so that wnt be a problem. but about the stock nav, your yukon should have premium bose sound from factory in order to connect a stock nav..............other wise, no go

The factory nav that i1m getting is plug and play, my question is that i have the d 3 installed now , will i have to change the wire harness to install the factory nav?

you basically answered your own question. You said the unit was plug and play your yukon has a factory connector still(unless you didnt buy the extra harness and hardwired the d3 harness in to the car) Then you would have to put your stock harness back in.

ok i lost the factory harness, would the dealer have one?

the dealercan get very expensive because they will charge you for an entire audio harness they wont just sell you a cut off peice. Your best bet would be to buyone off of ebay.

i dont know which year your car is.

But to make sure that you actually need this harness did you cut off the connector on the car and hardwire your d3 in?
