Project HUD

So I saw this on eBay and the price was too good to pass up...

Look at this on eBay:


Won it and its being shipped here and once the weather clears so I can drive the Camaro this is another little project to add to the car along with finalizing my brembo upgrade and egx body kit.

I'm hoping I can just cut the dash (it's hollow) buy the HUD defrost nozzle and wire it up with the HUD dash switch and it'll be a go.

Don't want nor need acc so that removes most of the headache however does anyone know if there's any special programming needed to activate this once I hook everything up or once wired up will it just work (highly unlikely).

Any assist guys? Especially looking for insight from the other gurus (this means you ddadler!)

Once turned on in the RIM/IPM will the Nav directions display on the HUD? Or is there some programming needed in the Nav module (radio) to enable that?

Also for my own amusement dealer said it couldnt be done but can you go under the tech2 manually as an 05 build and see if you can turn on the secure car feature?

Subject: Windows Will Not Express Up Using the Secure Car Feature

Models: 2005-2006 Cadillac STS

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

The 2005 Cadillac STS owner's manual pages 2-5 and 2-19 incorrectly state that the vehicle is equipped with a "secure car feature" that would allow the customer to express up the vehicles windows by pressing and holding the lock button on the keyless entry transmitter. This feature is not available for 2005 model year.
For 2006 model year vehicles the feature is available, however, some vehicles were built with the feature disabled. To enable the Secure Car feature on 2006 model year vehicles, perform the following:
****•* D
****•* STS
****•* RCDLR

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

I think you need to get a RCDLR from the 06 or newer car in order to do it.
I show them as being the same part number though. 07 is different thn 08-09 and then 10+. No idea why.
The 'secure car feature' has been discussed many times on the forum. The conclusion has always ended that only the very latest build 2005's could enjoy this nice feature.

On the original topic, it does make sense that HUD can be enabled without ACC. HUD was available on its own in many later-model STS but only V8's had ACC.
Yes but there is no difference in parts to explain why. Only a difference in programming which should be able to be overridden by a tech 2.
Sorry I couldn't respond sooner, but work was getting in the way :)

I believe when turned on, the HUD will display navigation information without further programming of the radio. Of course to try will determine this for sure. It makes sense though base on my past experiences. Personally, I would connect the HUD in a test configuration before taking your dash apart. From a person who's had his dash out twice, it is a fair amount of work if it turns out this is not going to work.

In regards to the configuration change, it has been my experience that changing an option setting in the IPM is automatically mirrored in the RIM and requires no direct interaction with the RIM. The BPP calibration is a separate procedure, also completed through the IPM menu options.

I suspect the 'V' series cluster will have different firmware as it is a different part number and is for a different application. It would make sense that information broadcast to it will be based upon the engine option selected through the IPM configuration.

I believe the Fog Lights not US/Can is for the rear fog lights. Even though I have enabled this, my car does not retain the last state selected during the previous ignition cycle.

As far as the "Secure Car" feature, while the module part number may be the same, the software loaded into the module when installed or replaced is different. This is not as simple as changing a setting with the Tech2. I had looked for a past member a long time back. This requires the use of GM's SPS (Service Programming System). You may be able to get a module from an '06 with a newer calibration already loaded to work, however the RCDLR is an integral part of several other systems in the vehicle and you may inherit a whole new set of problems. This component plays a key role in lock/unlock status, remote start, TPMS, etc.

Makes sense except if my rcdlr were to fail they would replace it. It would come as a blank slate no programming. Since an 05 and 06 is the same part they would be flashed with the tech 2 and programmed with whatever options are applicable and then sync it with the vtd so why can't my current 05 rcdlr have the ability for it?

That's down the road though

Will be hard to test the HUD if I need it turned on and a tech 2 to do it unless without the option turn on it still gets some data. Could you test turning off your hud in the rim and see if it has any functionality?
I understand what you're saying about the RCDLR. My guess is there are incompatibilities with software in other modules within the car. GM doesn't use a Tech2 for programming anymore, they use an MDI. With this, there have been changes to how this takes place. Just last week we had a problem with a radio I installed in one of our fleet vehicles a few years back. It had to be replaced and the dealership was unable to program it. They ordered the same part number I had installed. Back then, I was able to use a Tech2 for the programming and I was able to select a calibration of my choice. This allowed me to "trick" the system into letting me program it. Since I don't subscribe to SPS access anymore I can't try many of the things I used to be able to do. Working with the dealer we tried to install the new radio using my past method unsuccessfully. When you use an MDI for programming, it verifies VIN's and part numbers so this is where you'll be stuck.

I will try changing the option setting in the IPM but I won't get to it tonight. Tomorrow is my Friday so I'll try to get to it over the weekend.

I appreciate all the help/advice!

Just worried if that could end up being the case here with adding the HUD now....

Already found a good used HUD carrier for 250, was going to pick it up this weekend, replacing that doesnt bother me, I rebuilt an XLR and did a heater core on my old Seville both required removal of the dash carrier.

You can see my STS back when it had the Platnium grille in the last pic

Well it seems you are quite capable for sure. I really can't see why this won't work, but it is a PITA if it doesn't. When the dealer replaced my HUD under warranty, they broke away pieces of my carrier instead of removing the steering column the way they should have. If you take out the column, you may be able to clear the shifter. This is another area they broke to save a little work.

BTW, there is a problem with the link in your last photo. It isn't displaying properly.
retried it!

i agree i would rather not waste my time or money if this proves to be fruitless but I think it will work (in theory on paper it looks legit!)


Lets hope the RCDLR pans out...

07 module should have everything SET, we shall try this....

i think i take on too many projects at once... this is why my Camaro never gets done...

Give it a shot. Hopefully it will work for you.
Worst case for that one Ill need to reprogram my keys back to my OE RCDLR and I wasted $25 bucks if it doesn't work, or if it does Ill need to have the dealer clear it with the VTD...

The HUD is what I really want though hahaha

Ill wait till I head the status on the RIM once you shut off the HUD to decide if I wait to pick this HUD carrier up (pointless to waste money)

I may have them turn on the HUD in the RIM program the brake pedal and clear the VTD for the new RCDLR all at once, maybe Ill get away with just an hours diagnostic hahaha
If you have a look at the Hollander information on that eBay listing, it says "STS 07-08 Theft/Locking; w/o keyless entry". Hopefully this doesn't create a problem. I'm not aware of an STS without keyless entry, but for an 07-08 part, it does have a different part number on the case than mine.
All of them say that if you dig into it. No idea why. Maybe because our cars technically don't have keyless entry. It's called passive proximity or something special since you only need the fob on your person and not to actually press the unlock for access. I forget the exact name for it.
with regards to MDI/SPS programming vs the TechII if you want to flash a module or option that a vehicle doesn't have you have to call GM TechLine and get them to add that option to the VIN so when you program it with the MDI using the VIN the option is there

we ran into this recently turning on cruise control for a chevy cruze
(oh the irony of a cruze that didnt' have cruise)

the customer didn't explain themselves clearly to us and the tech and I worked for about a half hour trying to figure out why the customer would say that cruise wasn't working when the car clearly didn't come with the cruise control option

when we went back to the customer they explained better that they wanted us to turn cruise on... that was news to me
so my tech called techline and they said that this is the new normal - lots of simple options will no longer require new parts but just new software
so techline added the option and my tech reflashed with the MDI and all was good

So can I mail you this rcdlr rippy and have you turn on the secure car feature?

Also ever find out if the headlamp switch has a pigtail?
@1BadCadSTS - what is on your bumper on the STS in the last pic with the XLR (next to passenger headlight)?

Also, as you apparently have intimate relations with the XLR are there any parts for the XLR that could or should or that someone might want to be used on the STS?
Not really sure of all its features.
