I have a 2007 ESV with only 30K miles. Not sure why but all of a sudden I have an annoying rattle that sounds like it's coming from the Radio/Nav area. I took it in twice and they still can't fix it. The last time I had this experience was with a 2000 Honda Odyssey. After 2 attempts with the dealer I just removed the stereo myself, secured the entire area with tape and foam and the rattles were gone. I figured out the Honda easily but this is another story. I had a 2007 Denali and that was easy to negotiate as well but this has stumped me. Anyone have a clue?

If you go to the sticky above and download the $5.00 Nav unlock it details removal of trim and radio stack . Hope you get it !! One of Winters gifts is the amount of rattles that surface when it gets cold out.:banghead:

I did this to install the factory nav. It was real easy. Good luck man.
