I have a 2010 Enclave CXL. When I pulled into the garage today and turned the ignition off, the Nav screen opened automatically. I've never opened it before so I had to look up how to close it. When I pushed the screen back to close it, it wouldn't stay closed. It just slowly opened again. I tried again, same thing. So I called the dealer, because I didn't want to drive to tomorrow with the entire nav/entertainment screen open. I took the car in, and the service person tried to close it. It wouldn't close for him. He ejected the Nav DVD and a CD I had in the CD player. It still wouldn't close. He turned the car off and on and tried it again. Nope. He said he's never seen something like that before so he's not sure what could be wrong with it. Has anyone else experienced this? I have no idea what caused it to open. I was listening to the radio, turned off the car (my keys were still in the ignition), and the screen slowly opened. It worries me that the service guy never saw anything like this before. I hope to God they don't tell me I'm going to need an entire new nav system. Oh, the radio still played even when the screen was popped out. I could still see all the visuals on the screen too. The audio and everything still works, but the actual screen will not stay closed. Does anyone have any ideas? Thanks.
