Mine went pear shaped as well. Tried all the usual, dvd cleaners as well. Nothing worked. Then when cleaning my glasses with Boots Lens Cleaner, I thought why not? Nothing to loose. So I cleaned the dvd with the lens cleaner, then sprayed the cleaner onto the glasses cloth, got a plastic spoon and put it on the handle. Slowly and carefully, I placed it in the crv dvd aperture, wiggled it about back and forth, left and right several times. Another spray and repeated. Then I put the dvd in and it loaded! I did a force download and it is now back to normal, better than it was in the first place. Not sure how long it will last though - and I still prefer my tomtom, but at least I have the proper display on my CRV now as it was, rather than that stupid bl**dy message dvd error which was really getting to me. Has to be worth a go if nothing else works. I think the motto for this cr*ppy satnav system has to be Quando Omni Flunkus Moritati.
