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

Look at this on eBay:

GM 2006 CADILLAC STS REFURBISHED HUD - 15943543

http://bit.ly/153uLpl

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!)

Damn that is quite the price.
Likely ddalder will tell you that it will need to be enabled in the IPM configuration via the Tech 2.

Yup. Tech line is indicating I need to program the ipm and rim

Rippy I need a price on the info control switch with hud and the hvac defrost nozzle (plastic dash pad) along with connectors for the HUD and info switch. Can you work that up?

the info control switch ... that's to the left of the cluster next to the driver's side a/c vent outlet?
if so, that's
#25827229
$59.44 - list price
$42.35 - your price

and the connector
#88988295
$34.00 - list price
$21.25 - your price

the HUD connector
#88986454
$244.74 - list price
$152.96 - your price

the dash pad comes in two colors (ebony/black and cocoa/brown)
your vin might help in getting the correct color but it's possible you have an interior that the HUD option was not available with
(it was only available with RPOs 4AL, 4BF, & 4BC)
either way the price is very similar
list price ~$123
forum price ~$88

all parts still available from GM

My dash is indeed ebony (so I am assuming I need 25772897) as is the rest of the parts

Wow is the hud connector price high. What's so special about it is it a whole harness or simply the plug without any wiring?

it's probably a low demand issue due to the fact that the option was sold to a very limited number of vehicles
plus it's a premium feature

says it's 'with leads' so that leads me to think it's a pigtail

Set your expectations appropriately. HUD cars have a special polarized windshield. A standard windshield might not perform quite as well.

Illogically, that polarization is in the same axis as most sunglasses. Voila! Disappearing HUD!

Got my STS back from the shop today so I'll pull out my Tech2 and let you know for sure. I'm fairly certain it will need to be turned on. This is how the other modules know to broadcast data to it.

Thanks so much!

Checked the ipm and rim replacement info and it says you must turn on acc and HUD individually so I'm assuming ill be ok with just hud. The wiring doesn't scare me, just the programming.

Too bad your in Canada. I'd come to you and throw a couple bucks at you over the dealer just to power it on!

Vette boys have been doing it for years. Most say the difference is minimal. If it becomes an issue ill lay a small 25% tint square in the reflection area for the HUD

The window tint on my windshield has not increased or decreased the HUD visibility in my opinion.

Yeah. The entire car is tinted. 35% over OEM 70% tint on side and rear windows. 20% over the OEM moonroof tint. 50% over OEM 70% tint on windshield.

I have a medical exemption prescription from the tint laws in MN due to migraine headaches. Before tinted windshield I had roughly 2 a week now it's about 1 per month with the tint. Traded in the DTS with the same tint setup dealer didn't notice or didn't care and sold it as it was. My monte has 35% on all glass but its hardly driven and is typically only out summer daytime.

After poking around in the IPM/RIM setup configuration, it would appear that you can turn on only the HUD without having to activate ACC. The following screen shots are configurable options for the 2008 model year. I haven't looked into any other year. One point to note, anytime I've ever changed the configuration in the IPM, I've had to perform a Brake Pedal Position calibration. Since the RIM retains a backup copy of the configuration, it is automatically updated when anything in the IPM configuration is changed.

Foglamps not US/Can ... what does that do?

See anything about getting the V cluster features or did you not think to look? or are those all the options related to the IPM?

Probably has fog lamps remain in whatever state you left them in? Ie had them on shut off car restart they are on again without toggling? Or means export rear fogs.
