Thread: 04+ HUD Install

I bought a console off eBay that had the switch and switch-to-IP wiring already in it. I wanted to replace my console anyway because the prior owner had gotten cig burns around the ashtray and it bothered the **** out of me. It was like $75 and the console I bought was like brand new. So it all kinda worked out.

You have your wiring connectors? If not I have a HUD connector and an IP connector I pulled out of a car at a junkyard that you're more than welcome to. Pulled 2 sets because its nice to have extra in case I ****ed something up, but now I don't need the extra set.

Figured I'd give a wrap up on my situation as it is now solved. Background is that my GP is an 05 GT that had OEM nav from the factory but no HUD. I installed the HUD but wasn't getting radio and nav signal to display on the HUD. After a lot of failed attempts at solving it, I went to the dealer. Asked them to program the RPO for the HUD (UV6) so the PCM would see the signal from the radio and send it to the HUD. They pushed back and said they wouldn't do it because according to them the 05 doesn't get nav directions on the HUD, which I knew was bull**** because it states it in the service manual but it doesn't say how to program it. So I had them check the build sheet to make sure the nav was factory installed, and it was. That means the signal is there but the PCM doesn't know to send it to the HUD because it doesn't know the HUD is there. Went to another dealership, asked them to reprogram, they did, and it worked.

So, if you have nav and add HUD, you have to get a reprogram to get HUD online and accepting the nav signal to display turn by turn directions and radio station data . And vice versa, if you have HUD and decide to add factory nav, you'll have to get a reprogram to get the nav online too.
