Just an FYI. I recently had issues with my dvd changer in my 2010 LR4. It would only play certain DVD's. I had read on a forum that if you got one of those cleaner disks it would likely do the trick. That didnt work. I ended up tearing out the trim and removing the DVD. After I got it out I thought i would try one more thing so I went and bought a bottle of isopropyl alchohol and a q tip and manually cleaned the optic eye. I put it all back together and low and behold it now plays all DVD's. just a $2.00 bottle of alchohol and a little work getting the player out was well worth it.
