Walking out to the truck the other evening at the grocery store. It was 96 degrees. Lady pulled up next to the Yukon in a Navigator and checked out the interior of the Yukon as she got out, I hit the remote start and fired up the truck and the AC. She kinda jumped. Then as she went around the back of the truck to go into the store I hit the remote hatch and walked up to the truck. She stops and watches the whole deal and then I hit the door button and it closed as I put the grocery cart in the rack. She comes over and asks all sorts of questions... I think she's trading her Navigator. I never thought I'd use these features but they are mondo cool.
