The weirdest thing has been happening to me the past few months. Currently, I live in Columbus, OH but a couple times of month I'll drive to Michigan (Metro Detroit) for the weekend. While in Michigan, I would occasionally return to my vehicle find find the truck open. Now I've read this was a common occurrence with the 2004 e60's (which I have) and can be fixed with a software upgrade. What puzzles me is that this only happens when I'm in Michigan and not Ohio. Could I be picking up a frequency that is the same as the trunk button on the remote? Very Weird

Thanks,
Will
