Just wondering if anyone could perhaps get me a copy of the 4.56 NAV disk? My unit scracthed mine and Acura is not wanting to warranty because "The nav unit wouldnt scratch the disk..." but yet there is a perfect circle engraved into it...i just need a copy for a quick fix...pm me if you could help out plz...

 

theres a TSB on this, It was in mid to late 2006 or in 2007.

 

here it is page 2, it applies to MDX's but it should show them that the disks to get scratched in the player.
