I'm wondering if anyone can help me, in navigation map screen while selecting end point there are two choices, tap on screen or contacts,when I select contacts it prompts me to open menu,settings,contacts,two options, import/export, I select import and it searches, here's the problem, it says no vcard file found, 1, what does this mean? 2, how do I get contacts to load to nav end points? Is this user error or software problem? Any help is greatly appreciated,
