Thank you both for your replies. Let me state that I have a Limited edition. It has all the side sensors and all, and I believe even the top 360 cam, just not accessible for me to press a button to view. I have the blind spot sensors and everything on the mirrors and when backing up, it notifies me when and from which direction cars are coming from. So that stuff is there. Whether there is more to it from that, which no doubt there is, I don't know. I know when you order the package on a new vehicle it is a $1,000 package. I figure it would at least possibly be that much to add it on. Just didn't know if it was possible. Figured possibly cheaper being as some of the electronics might already exist. Regardless, didn't know if anyone knew. Appreciate the replies.
The DAP gets you:
• Adaptive Cruise Control with Stop-and-Go
• Auto High-Beam Headlamp
• Lane-Keeping System (Includes Lane-Keeping Assist, Lane-Keeping Alert and Driver Alert)
• Pre-Collision Assist with Pedestrian Detection and Forward Collision Warning
Those things are almost completely handled through a pair of sensors in the front of the vehicle (one is in the rear view mirror housing and the other is in the front bumper area
The systems you describe your vehicle already having on-board (proximity sensors, BLIS, 360 camera, etc) are separate systems. I'll bet your vehicle is equipped with either the Special Edition Package (which includes 22" wheels, the 360 camera, HD Tow, enhanced park assist, and LED lighting) or the 302A package...neither of which include the DAP package components.
There are a number of places online you can lookup your window sticker using your VIN (or at least there used to be)...I'd do that to see what the vehicle was ordered with.
Point being, I don't think you have the sensors in the rear view housing or the bumper which are required for the DAP systems.
