They've got this really big machine out in back of the service center. I've seen it. The machine is like a big chicken rotisserie on a barbque. They take these really soft moving pads and put them on the front and back of the car. They spin the car around and use shrink wrap to secure the pads. Once they get it wrapped, they pull the two pieces of the big machine apart and slide it over to the front and back of the car. They use the really big flat bungee cords to hold the front and back machine piece on the car. Just before they turn it on, they use the car's GPS to align it so its front points true north The turn it on. This shakes the car up and down and back and forth while its turning it like a pig on a spit. Not only does it calibrate the AP1 radar, it cleans the golf clubs in the trunk and knocks the loose screws and nuts stuck inside the doors. The last action done before they shut it down is turn the car upside down to let the stuff in the doors fall out, and the dirt loose from the clubs. The tricky part of this is, the true north only works on the first and last week of each month.
