Well you didn't answer the most important questions I asked about how your LEDs and horn.
In any case, if you don't want the system, you could always take a shot at removing it. If it's dealer or port installed, I'd say there is a 90% chance that you'll find tucked up in the driver side lower dash. Just remove the two bolts and snap that panel off to have a look. Look for wire taps, or zip ties. They'll lead you to any aftermarket modifications.
Alternatively, if the system was delivered with your new vehicle, try talking to the dealer service manager. It should be covered under your new car warranty. At the very least, they should know how to deactivate the thing.
