Even though I'm one of the new guys, but no n00b by any stretch, I figured it wouldn't hurt to make a contribution. I know there's a few HUD installation write-ups floating around here or there for us 04 and up guys, and all are helpful in their own way. But for those of us, myself included, who cannot access the write-up over at ClubGP, I wanted to create another HUD install write up. And I've had terrible luck finding the link to the other write-ups. So I'll try to consolidate all the information that I've found into one post and give credit where credit is due along the way. Call it an 04+ HUD install for Dummies. I will update this post often, although I haven't received the HUD from Ed Morad yet. But I will take pics and give detailed installation instructions throughout the project. TIA to Scott(chethammer), Flip, duane9586, unstable, and Ryan Alan(CarDomain illustrated HUD install pics) for their hard work and contribution to this write-up! As you can see, this project is the ingenuity and courage of others, not myself, and i do not intend to take credit for their work in any way by creating another write up, just to be clear.

Thanks,
Nathan

"HUD"- Head-Up Display, capable of projecting 18 different functions onto the windshield including audio system information, speed, compass, outside air temperature, PRNDL, "Stealth" mode, intermediate gear positions, performance upshift light, high beam indicator, and warning lights such as head lights suggested. 2005 cars with Nav systems the HUD will display driving directions. -courtesy of Flip and Bleen


Owner's Manual HUD info:


HUD components:

HUD dash trim piece (GM P/N: 10354107), HUD Display unit (GM P/N: 10387483), HUD Wiring Harness (GM P/N: still searching)


HUD adjustment switch (GM P/N: 10438819)


Compass Module (GM P/N: 15236913), Outside Air Temperature Sensor (GM P/N: still searching)


Tools needed/reccomended:

Flathead screwdriver (to remove the upper dash trim piece which is held in by plastic clips)
utility knife or razor blade (for precision while cutting the dash padding)
Dremel or some sort of rotary too with a QUALITY cutting wheel (to cut through the hard plastic dash under the dash padding)
Soldering tool or electrical tape (to conceal exposed, spliced wires)
18/5 (18 gauge/5 wire) Thermostat wire to wire the HUD to the adjustment switch (it's color coded and keeps eveything bundled together neatly)
18/3 (18 gauge/3 wire) Thermostat wire to tap into the DIC if you choose to go that route rather than tap into the IP

Electrical Wiring
-I would strongly suggest taking care of the wiring first, especially if you're electrically retarded like me. I was lucky enough to obtain a wiring harness for the HUD and adjustment switch, so fortunately it was all just plug n' play after I wired everything together correctly. If you don't have a wiring harness, then definitely wire everything together first. One, to avoid any mishaps later in the project and two, you're obviously not going to able to fit your hands inside the dash to do the wiring unless you have the whole dash taken out of the interior of the vehicle.
-The wiring harness will have multiple plastic connectors or "clips" that the wires lead to, kind of like a plug at the end of an electrical cord. But instead of one fat cord, in this instance you will see many tiny electrical wires leading to a clip. Each one of these clips or plugs will have eight wires leading to it, all of which are color coded to represent the information that each individual wire sends to/from the vehicle. Duane 9586 came up with a good representation, shown below:

Top of one of these "clips"
1 2 3 4
5 6 7 8

HUD harness
Wire # color what is it?
1-brown/yellow-data
2-yellow-up control
3-brown-down control
4-black/white-ground
5-white-illumination
6-orange-12V
7-brown-switch signal
8-white-low referance

Switch harness
Wire # color what is it?
1-grey-switch illumination
2-black-ground
3-white-low referance
4-brown-down control
5-brown switch signal
6-white-illumination
7-yellow-up control
8-blank

"As you can hopefully see the HUD and switch harnesses share 5 wires minus the ground wire. These 5 (low referance, down and up controls, switch signal, and illumination) are the wires that will be directly hooked up. The two remaining wires on the switch (switch illumination and ground) I simply tapped into the traction control wires to provide the ground and red illumination. [NOTE: My GP did NOT come with Traction Control, so I will come back to this... -Nitemare_05GP]

The remaining 3 on the HUD harness (12v, ground, and data) I tapped into the IP cluster. You could use the DIC also but the IP is right there and made a logical choice.

(I have to check the following when I get home to make sure I have the correct colors matched up)
The brown/white DATA wire goes with the gray IP (Instrument Panel info) wire
The black ground remains the same color along with the orange 12v." -courtesy of duane9586

Scott(chethammer) has informed me that when Ryan did the HUD install he had the dash nearly taken apart so it was much easier for him to access the wiring in the IP area than it would be for me. So he advised me to tap into the wiring harness for the DIC, which recieves the same information as the IP. I will update this portion of the write-up as I do my own version of the HUD install, using the DIC wiring harness.

Dash Modification
Step 1: Take off both A pillar covers (L). Start at the top and pull towards the center of the car. They're held in by clips, so no tools required.

Step 2: "Take off the dash trim piece (H), commonly referred to as a 'cowl.' Start by the driver's side and work it out. Again, it's held in by clips, so just pull straight up (as possible). I had to work from both sides of the car, pulling a couple of clips at a time until everything released. There is a light sensor (J) and a theft-device LED (I) attached to the cowl. Scott recommended that I disassemble the units but, in my case, twisting the body counterclockwise from the bottom released the entire unit in both cases. A quarter turn was all it took, then the cowl was out. Pretty easy." -courtesy of unstable
This "cowl" is removed a) to prepare the area of the dash where the HUD will be housed in for cutting and b)to make room for the new HUD style cowl which you will lay down on top of the dash as template for cutting the dash.

Step 3: It is easiest to remove the clips from the new HUD dash piece before you set it on top of the dash to trace around the outer edges of it. This is is the part where you have be PRECISE: you don't want to cut too wide of a hole in your dash because you traced too wide of a line around the HUD trim piece. Tape off about a 1/4 inch inside your line on all three sides to prevent any mishaps. You only have one chance, really, and after you start cutting into your dash there's no going back so you want to be sure to do it right the first time. You can use chalk or dry erase marker, as long as it's something that easily seen and easily removable.

Before proceeding any further, it is HIGHLY recommended that you protect your windshield with duct tape or blanket, or something. Or tape cardboard up against your windshield. The area between the windshield and the dash where you will be cutting is a tight space and it would be easy to nick the glass and create a nice lil scar. "You WILL cut all the way back to the firewall near the windshield and then across. The HUD goes all the way back to the back. It doesn't look like it will but it does." As you can see in the picture below

I would love to do this, can you let me know how much all of this is costing you? did you need a new windshield as well?

same as above..only thing that worries me is the cost..

well on the 97-03 GPs you do not have to change the windshield.

lol looks like mayben and i r screwed..

sorry for the slow reply, guys. 01GPGT is correct, you do not have to have a special windshield to make this install work, but vehicles that come factory equipped with a HUD have a windshield with a much higher clarity rating than regular windshields so they can display the HUD image clearly. I have heard that there is a slight "ghosting" effect if you use a HUD on a normal windshield but it is not so bad that it affects the HUD image to the point that's it's not discernable from the windshield. I will not be getting a new windshield for this project because they cost a significant amount more than a normal windshield, and it's not really necessary



I'm gonna warn you now guys, this project can get really expensive, really fast. Especially if you prefer to use new parts. I would HIGHLY recommend going to Ed Morad for the parts, I'm sure others can chime in on his credibility. He sells everything you could ever need for the FWD 3800 platform at a reasonable, competitive price. They are used parts,but guaranteed to work. Thankfully I was able to find the HUD, dash trim piece, wiring harness, and switch as a package deal for a little over $200 but I still do not have a compass module or temperature sensor, both of which are well over $100 from a dealership. If you could find a wrecked, fully loaded GTP at a salvage yard with an intact interior, you'll be set. This may not be a cheap upgrade, but IMHO it's well worth it.

I look forward to seeing progress! Good Luck!

Why have more money than brains? Cuz RACE CAR :

if you use a temp sensor from a 02 Tahoe they are the same and a lot less cheaper
but idk about the compass module

_________________

Thanks z3ro, I was actually wondering if the temperature sensors found on many other vehicles would work just as well. It'd be great to find a cheap compass module, too. Best price I've seen so far is $90 from MonstarPartsOnline.

i know the 97-03 gtp has the outside temp sensor for the digital dual hvac and that was on the passenger side between the radiator and the fog light

_________________

So I'm guessing most temp sensors would be located between the front bumper cover and the radiator? Its just a matter of figuring out where it is and what one looks like exactly...

Its really easy to find the temp sensor. Just look down under your front bumper almost in the center behind the bumper cover and in front of the radiator. Its in a hole (not kidding) and its a little green plastic thing.

Here's a word doc on how to do the entire 5 button install. ITs a 2.2 Mbyte file though. Click on 5 button in the links on the right.

My 06 GP GT has the plug for the hud behind the i/p. It was taped to the i/p plug harness in the dash (inside the hole where the i/p plug sticks out). Also, if you have the wire harness for the hud switch all you have to do is swap the old harness inside your center console with the new hud switch harness. I ordered a new center console trim plate from monsterpartsonline.com that had the hole for the new hud switch. I tested the hud and switch to make sure it worked and it did. I'm just waiting for the dash trim piece to come in so I can cut my dash.

Great write-up. Seems like a lot more steps needed than on the 97-03. What a fun task that was wiring into my SE haha.

On a side note.... I see the myth of needing a "special" windsheild is still flying around haha.

Why buy something sensible with a RWD setup when you can build something really stupid, like this

So Im have the 04 gp with HUD but what would I have to do to get turn by turn navigation displayed on my heads up display..... That you woul d be cool if there was a write up on that.

it would be awesome to modify this to work in a 97-03 gp. both of my gp's have HUD, I installed the one on my se, but i like the look of the 04+ HUD much better. and "look" as the digital layout.
