I can't start navigon 5.2.0, nor 5.1.0.
I read from threads here about it's earlier versions, and some others had same kind of problems with it before, but no answers.
when starting prog:
it first tries to 'check' registration, then 'to do' registr., and fails to 'error has occurred', check your network and/or internet connection, though my wlan and sim are working ok.
I tried LP auto, inverse and extreme to remove license check, but it did not help.
Any suggestions? I guess it works well in your phones...
