Hello, I have used the help or search function but found nothing useful. My problem is that Navi reports “Navigation not available at the moment”. As if the Navi-DVD was not readable or not inserted. I tried to remove the DVD, but the player doesn’t jump out the DVD anymore!!! Does anyone know this problem? How do I get out the DVD? Is there perhaps some kind of music lock? Does a reset at the ZAB help perhaps? Would be nice if one or the other had a little advice for me. Allen still a nice day. Greet Markus
