Since updating to iOS4 Navigon has display issues with the panorama 3D mode. It now has double street names and poi's. If I turn it off and use the normal 3D, all returns to normal. Has anyone else observed this problem? I will probably try to unistall the panorama 3D add on, and then reinstall it to see if that helps. Please check it out and see if your Navigon has the same problem. Thanks.
