Hello, I'm new to the forum and just purchased a 2016 kia soul base. I would like to add the factory navigation system into this car. My question is are these cars prewired for all models or no? Has anyone done this before? I also want to add OEM fog lights and switch as my state requires fog light to work only on low beam. I just like the factory look on vehicles. I used to have a Silverado and everything was prewired and plug and play. Any help would be greatly appreciated. Thank you.
