Today after a nice drive, I came home, parked the car and turned off the engine. I had the the Bran Van cd playing, and while I reached in the back to get my bag, the music was still pumping out loud...I looked in my hand and yeah there were my keys.

I started the car and turned it off again, and repeated this five times, but to no avail..Bran Van kept singing "we go shopping",
Just to check if the other "electronics" were possesed too, I pushed the "folding mirror" button(yes the Jap. version comes with electric folding mirrors), they closed halfway, stopped and Bran also stopped....

I started the car again and shut it down several times, but the problem didn' t return...

Any ideas what may have caused this?
