Hi Brown Dog and others,
I can now confirm that this iGo version works 110% and is stable on my Note2. Finally succes after many attempts. iGo remains my favourite navigation software so I'm happy it worked out this way.
For me the trick was to install the downloaded version without changing language and voice files at first. Choose English for language and voice and don't delete any other lang or voice file. Then run the program and exit after everything tests OK. Now add (in my case) the Dutch lang and voice files and change to those in settings. Next add maps, buildings, POI as needed and navigate away...
Thanks for your help!
