I misunderstood their "factory installed" towing package. The wiring is factory instal led, the towing and braking system are after market and not as attractive as the Kia. After all my conversations about camping trailer, they installed a boat trailer system and I insisted they pay for 7 pin and braking.
I use a "Echo" by Curt brake controller. It is bluetooth adapted to your smart phone. Install an app on the the and you can access your controller to make brake adjustment to the trailer. Plug into the 7pin and the trailer plug is inserted into the controller.
