I have a 2006 Sienna. The battery was recently changed and now the navigation/dvd/backup camera is not working. The dealership told me that they do not know what is wrong with it and are not aware of anyone willing to look at it. They suggested a replacement at $6300. Crazy. I hope someone can help. The screen says "No Map DVD Insert Map DVD" I have taken the map dvd out and re-inserted it with same prompt.
Thanks
