Hello. I just installed Connect Nav+ it had Master Code, so I installed 9.8 version and it works fine, just I couldnt turn off Nav+ completly so I just plug off it for night. In morning I connected it and Setup menu was showing and I can't turn it off. I pressed everything but no good. I tried to reflash 9.8 and I couldnt do it.

Can any one help my with that? How to make Nav+ work completly to my

Also if I will update system to newest version will Master Code will show up again?
