Looks like I may have to do the same on our 2007 Nav. The fuse has blown twice now, and the steps are in, thankfully. I may just replace all the tracks if I have to do any. Did you have a parts list or anything to reference, or did you just keep pulling bolts until it came down? Any other tips you'd care to share. Thanks!
