Hi lads, just bought my ATS 2015 2.0T performance, the issue is that there is a HUD projector, but there is no button on to switch it on. So i was wondering if its possible to some how install the HUD add, like add these buttons for HUD or there is missing more to it?? Anyone tried?

The HUD would not be an easy retrofit. The projector sits behind the gauge cluster on a bunch of mounting hardware that isn't there if you don't have the feature. The gauge cowl is also different since it has a big rectangular cutout on top. The HUD controls would have to be added along with their wires. HUD equipped ATSes also have different windshields that properly reflect and refract the light coming up from the projector. Finally, there's no telling if the non-HUD DIC unit will just work if you connect in the HUD hardware. I'd like to believe that they wrote the software in such a way that it will just work in any car, but Cadillac has made a lot of inter-trim incompatibilities, so I wouldn't be surprised if they didn't work.

Everytime i turn the ignition, i see a red reflection on the window.. attached a photo of it... is that the projector??
I don't see the attached picture, but as SaveTheManuals said this is probably just the collision warning lights.

What you show in the photo is not HUD. As previously noted, probably projects the red collision warning icon.

I have added a HUD projector to my 2015 Performance edition, the tricky part is getting another instrument cluster that is HUD enabled and programmed to your car. You have to change the hood over cluster, bracket under the hood, different knee bolster panel with HUD controls, I have pics on my IG: CrakaLac337

How was the wiring aspect of adding this?

Really simple, 3 wires on cluster harness need to be spliced into. The cluster to hud is a mini-usb, 2 wires run from HUD to HUD switch. The lane-assist and parking sensor switch is different so you have to splice it.

Again the trickiest part is getting the proper cluster with HUD port and having it programmed to the car. I can make harness to do the conversion

Hmm alright. And how did you know the correct cluster to buy? This sounds doable once you have the parts.

You need the cluster from a similar model year car with RPO UV6, that’s the code for HUD display option. I do not know anyone to program clusters currently, I am looking into getting the hardware/software to try out

Don't you need the specific HUD capable windshield glass too? Or will it work with non HUD glass but just not as well or something?

I plan on swapping later, I am just using one of those HUD vinyl cutouts you see on amazon or eBay, otherwise it is slightly out of focus

The cluster for HUD has a second port on the back, that’s how you can tell if it is correct or not. It is a mini-usb connector

I am getting my windshield replaced due to a rock chip that turned into a giant crack, maybe I should consider getting the HUD version. hah
