I recently purchased an ES350 and love the car except the navigation system lockouts while driving. I have tried several hybrid discs on different brand discs, but have not been able to get them to work. I have tried disconnecting the battery to reset the nav, but this does not work. I tried to find the fuse, but it is not listed in the manual. Is it possible that by removing the fuse, it may reset itself to 5.1? If so, where and which fuse is it? I am open to any suggestions. Thanks to anyone who is willing to help.
