Doesn't matter that it worked on older version, not all functions are migrated from older to newer versions, same was for iGO8 and iGO Primo on WinCE platform. So f you have some suggestions or aditonal questions, maybe right adress for you is to write NNG and to ask them why that function is missing in iGO Primo for Android platform.

In meantime you can use Navigon, like i suggested you for that function and connecting with calendar's events.

For say thanks, please use button LIKE, it's located on right bottom corner in every post.
