I understand your confusion and frustration. Let me help a little bit. But first, I was a participant/bought one, I am not involved other than promoting or bragging about it.
The evappliques.com site is now
ev-acc.com Check it out.
What I was bragging about is the front mounted rear camera. If you look under Products Coming Soon, you can help by making a reservation to indicate you want one too. This idea was the brainchild of artsci, so was the lighted T and Lighted Rear Applique and dozens of other mods. Artsci is a Model S Mod Genius. Look for his thread that nothing but a running list of his mods to his car. Its an all day read itself. Back to the front cam kit. Those first Model S did not have parking sensors. May of us were breaking parts or tearing stuff off our cars when we pulled to close to curbs. Artsci started looking for a way to stop the problem. It was not good enough to simply put a camera and another screen in the car. He demanded from himself that it integrate into the center console. It took more than a year and during that time others joined his project and they created the very best mod we can do to the car.
Its a rearview/backup camera mounted on the front of the Model S (both classic and refreshed) so you can see where the front of your car is as you pull forward, not just to a curb, but also in your garage or a wall or even in traffic to another car. The best part is you see it on your center console AND you don't give up access to your backup camera/view when you need it. The solution even included it automatically swapped the view from the front to the rear when you put the car in reverse. And when you put it back in park or drive, it moved back to the front camera. You weren't stuck with having to leave the front cam or rear cam on the center console all the time either. Want some other screen up, do it.
Back when artsci started working on this, there were only about 3-4000 Model S in existence. By the time it was ready/done for installation there were about 22,000. But only 100 of the printed circuit board switch were in the first production run. These are not Tesla items. If you were not part of the first 100, you were out of luck. I would guess than 50% of those first 100 have been resold and resold on ebay and panjo over the last few years. I've had a couple. I moved mine from my '13 classic to my '17 refresh and its still the best mod e-v-e-r, and I have several mods on mine as well.
If enough people sign up for a reservation, you might be lucky enough to get the switch. Its the hardest component of the kit to collect. You folks have the easy part. All you have to do is put your name on the list and pay for it when its got all the items done and tested. Artsci won't release a product unless its right - it works. So think about it. I could be wrong, but it looks like the "team" is working on the Model X and Model S Lighted Rear Applique and Model X lighted T right now. I hope for each of you that he wraps up work on those and gets back to the front cam kit switch. There's my two cents on the subject.
